Abstract
Background and Aims Acne vulgaris remains one of the most common and problematic dermatological conditions. Recently, a fractional 1927 nm thulium laser has been developed with specific water absorption characteristics which may be of interest in the treatment of acne. Subjects and Methods Nine consecutive Korean subjects, 6 females and 3 males, ages ranging from 13 to 33 yr, presented with a mixture of inflammatory and noninflammatory acne. Baseline clinical photography, image analysis and lesion counts were performed. A fractional 1927 nm thulium laser (FTL) delivered 6 treatment sessions in 5 subjects and 5 sessions in 4 subjects, 4 weeks between sessions. Pain during treatment was assessed. At 32 weeks after the last treatment session, an independent Investigator Global Assessment (IGA) performed lesion counts and graded the severity of the acne at baseline and the final assessment on a quintile scale. Data were analyzed statistically. Results All 9 subjects completed the study with significant reductions in the inflammatory and noninflammatory lesions (P values 0.0012 and 0.0081, respectively) with overall lesion counts at the final assessment ranging from 60% to 97.1%, and acne grades in the IGA dropping by an average of 1.67 (range 1 to 3 grades). There was no significant difference in lesion counts or acne grades between the subjects who had 6 treatments and those who had 5 (P = 0.7695). Mild pain was reported during treatment, and no adverse events were reported by either the subjects or investigator. Conclusions The FTL at the parameters used in the present study caused disruption to the upper portion of the affected follicles and sebaceous glands under an intact stratum corneum, thereby destroying or damaging the causative Cutibacterium acnes. The superficial controlled coagulation additionally induced follicular remodeling and tissue regeneration, potentially contributing to the noticeable results in inflammatory and noninflammatory acne lesions.

Abstract
Acne vulgaris, a prevalent dermatological disorder, frequently affects individuals' self-perception and general psychosocial functioning. The growing demand for home-based light therapy devices prompted a systematic review to assess the efficacy of visible light in acne treatment. Overall, 35 studies were included, representing 1185 cases of acne vulgaris (mean age: 23.7 years; sex: 63% female). A total of 69% of the included studies were level 2 evidence. Overall, 92% of patients achieved partial remission of their acne lesions using visible light therapy. Among the patients who experienced a partial remission of their acne, 46% experienced a reduction of 0% to 50% in their acne lesions, while 33% and 12% experienced reductions of 51% to 74% and 75% to 99%, respectively. Notably, blue light emerged as the predominant treatment modality in this context, used in around 64% of the cases. A total of 95% of the patients who were treated with blue light experienced a partial clearance of acne lesions; 44% experienced a reduction of 0% to 50% in their acne lesions, while 42% and 9% experienced reductions of 51% to 74% and 75% to 99%, respectively. Overall, the average total lesion count improved by 43% at week 4 compared to the baseline. The average number of treatment sessions was 22 (range 1-112 sessions). On average, treated patients responded within a period of 4 weeks. Commonly reported side effects included skin irritation and erythema. This review highlights the potential of visible light therapy in acne treatment. Head-to-head studies are needed to compare the efficacy of visible light compared to existing therapies for the treatment of acne.

Soliman J, Elsanadi R, Messele F, Kelly KM. The effect of combined red, blue, and near-infrared light-emitting diode (LED) photobiomodulation therapy on speed of wound healing after superficial ablative fractional resurfacing. Lasers Med Sci 2024; 39:94. [PMID: 38532146 DOI: 10.1007/s10103-024-04042-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Accepted: 03/14/2024] [Indexed: 03/28/2024]
Abstract
Objective of the study is to assess the effects of wound healing with a commercially available light emitting diode (LED) photo biomodulation (PBM) device that emits three wavelengths (465, 640 and 880nm) after ablative fractional laser (AFL) treatment to healthy skin on the bilateral inner biceps. We conducted a prospective intraindividual randomized controlled study with 25 volunteers. AFL treatment was performed on healthy skin of the bilateral inner biceps. Subjects applied the LED light device for 30 min to the assigned bicep 3 times a week over 4 weeks, beginning on day 0. Subjects were followed up on days 2, 4, 6, 9, 13, 20 and 27 for treatment with the PBM device, clinical digital photography of the test and control sites, and in-person subject assessment, with follow ups on days 34 and 55 for clinical photography and assessment. Three blinded evaluators were asked to determine which bicep healed faster between day 0 to day 13. Pain, discomfort, and itch were also assessed. The three blinded evaluators chose the treatment arm as the faster healed arm in greater than 50% of the images, although the results were not statistically significant. There was no statistically significant difference between test and control arms in terms of pain, discomfort and itch. In conclusion, PBM therapy has the potential to improve wound healing. In this study, a three wavelength PBM device resulted in some subjects achieving faster healing after AFL but the results were not statistically significant.

Abstract
Electromagnetic radiation, notably visible light (VL), has complicated effects on human skin, particularly pigmentation, which have been largely overlooked. In this review, we discuss the photobiological mechanisms, pathological effects, clinical applications and therapeutic strategies of VL at varying wavelengths on melanocyte biology and skin pigmentary disorders. Different VL wavelengths may impose positive or negative effects, depending on their interactions with specific chromophores, photoaging, ROS production, circadian rhythm and other photon-mediated reactions. Further in vivo and in vitro studies are required to establish the pathologic mechanisms and application principles of VL in pigmentary disorders, as well as optimal photoprotection with coverage against VL wavelengths.

Abstract
The aim of this study was to examine the inhibitory effect of blue light (BL) on the proliferation of metastatic cancer cells and synergistic properties with chemo-drugs. BL significantly inhibited the proliferation of B cell lymphoma (A20 and RAMOS) cells in a dose-dependent manner. Anti-proliferative effect of BL irradiation was identified to be associated with the inhibition of proliferating-cell nuclear antigen expression and cell cycle by decreasing S-phase cells. Consistent with its inhibitory effects, BL irradiation at 20 J/cm2 daily for 10 days inhibited metastasis of cancer cells which were distributed and invaded to other organs including bone marrow, liver, kidney, etc., and induced paraplegia, thereby leading to an increased survival rate of tumor-bearing mice. Anti-proliferative activity of BL was expanded in solid tumor cells including pancreatic carcinoma (Mia PaCa-2, PANC-1), lung carcinoma A549 and colorectal carcinoma HCT116 cells. Additionally, combination with chemo-drugs such as 5-FU and gemcitabine resulted in an increase in the anti-proliferative activity after BL irradiation accompanied by regulating mRNA translational process via inhibition of p70S6K, 4EBP-1 and eIF4E phosphorylation during cellular proliferation. These results indicate the anti-metastatic and photo-biogoverning abilities of BL irradiation as a potent therapeutic potential for repressing the progression of tumor cells.

Abstract
The efficacy of blue light therapy in dermatology relies on numerous clinical studies. The safety remains a topic of controversy, where potentially deleterious effects were derived from in vitro rather than in vivo experiments. The objectives of this work were (1) to highlight the nuances behind "colors" of blue light, light propagation in tissue and the plurality of modes of action; and (2) to rigorously analyze studies on humans reporting both clinical and histological data from skin biopsies with focus on DNA damage, proliferation, apoptosis, oxidative stress, impact on collagen, elastin, immune cells, and pigmentation. We conclude that blue light therapy is safe for human skin. It induces intriguing skin pigmentation, in part mediated by photoreceptor Opsin-3, which might have a photoprotective effect against ultraviolet irradiation. Future research needs to unravel photochemical reactions and the most effective and safe parameters of blue light in dermatology.

Abstract
Melasma is a common refractory acquired pigmentary skin disease that mainly affects middle-aged women. The pathogenesis of melasma is still uncertain, while abnormal vascular endothelial cells may play a role. We previously demonstrated the yellow light of light-emitting diodes (LED) could inhibit melanogenesis through the photobiomodulation (PBM) of melanocytes and keratinocytes. In the current study, we investigated the effect of 590 nm LED on the function of human microvascular endothelial cells (HMEC-1). We revealed 0-40 J/cm2 590 nm LED had no toxic effect on HMEC-1 in vitro. 590 nm LED irradiation significantly reduced cell migration, tube formation, as well as the expression of vascular endothelial growth factor (VEGF) and stem cell factor (SCF), a pro-melanogenic factor. Moreover, we illustrated that 590 nm LED inhibited the phosphorylation of the AKT/PI3K/mTOR signaling pathway, and the inhibitory effect on HMEC-1 could be partially reversed by insulin-like growth factor 1 (IGF-1), an AKT/PI3K/mTOR pathway agonist. Besides, we conducted a pilot clinical study and observed a marked improvement on facial erythema and pigmentation in melasma patients after amber LED phototherapy. Taken together, 590 nm LED inhibited HMEC-1 migration, tube formation and the secretion of VEGF and SCF, predominantly through the inhibition of the AKT/PI3K/mTOR pathway, which may serve as a novel therapeutic option for melasma.

Abstract
Visible red light (RL) therapy is a rapidly expanding treatment option for dermatological conditions, including acne, psoriasis and chronic wounds. It is currently unknown if high fluences of RL induce DNA damage via reactive oxygen species (ROS) stress or other pathways. Our lab previously demonstrated that RL generates ROS in human dermal fibroblasts (HDFs). Other studies show that UV and blue light generate ROS and DNA damage in fibroblasts. This study aims to determine if RL induces DNA damage in HDFs. We found that 320 J/cm2 , 640 J/cm2 and 1280 J/cm2 RL (633 ± 6 nm) did not measurably increase DNA damage in the form of cyclobutane pyrimidine dimers (CPD) or 6-4 photoproducts (6-4PP) immediately, 3 hours and 24 hours following irradiation. Our study further supports that RL therapy is safe in human skin fibroblasts.

Abstract
Photodynamic therapy (PDT), as the name suggests is a light-based, non-invasive therapeutic treatment method that has garnered immense interest in the recent past for its efficacy in treating several pathological conditions. PDT has prominent use in the treatment of several dermatological conditions, which consequently have cosmetic benefits associated with it as PDT improves the overall appearance of the affected area. PDT is commonly used for repairing sun-damaged skin, providing skin rejuvenation, curbing pre-cancerous cells, treating conditions like acne, keratosis, skin-microbial infections, and cutaneous warts, etc. PDT mediates its action by generating oxygen species that are involved in bringing about immunomodulation, suppression of microbial load, wound-healing, lightening of scarring, etc. Although there are several challenges associated with PDT, the prominent ones being pain, erythema, insufficient delivery of the photosensitizing agent, and poor clinical outcomes, still PDT stands to be a promising approach with continuous efforts towards maximizing clinical efficacy while being cautious of the side effects and working towards lessening them. This article discusses the major skin-related conditions which can be treated or managed by employing PDT as a better or comparable alternative to conventional treatment approaches such that it also brings about aesthetic improvements thereof.

Abstract
Acne is a chronic inflammatory skin disease of the sebaceous glands of the hair follicles, caused by a variety of factors and tends to recur, causing skin damage and psychological stress to patients. Blue light (415nm) is a popular physical therapy for acne, however, studies on the effects of blue light on skin surface lipids (SSL) have not been exhaustively reported. So, we want to investigate the difference in SSL before and after acne treatment with blue light and to reveal the potential mechanism of acne treatment with blue light from the lipid level. SSL samples were collected and physiological indicators (moisture content, transepidermal water loss (TEWL), sebum content and pH) were measured. By using ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) with multivariate data analysis methods to obtain specific information on the lipid composition. Analysis of the physiological index data showed a significant increase in moisture content (p = 0.042), pH (p = 0.000) and a significant decrease in sebum content(p = 0.008) in the after treatment area (AT group), while there was no significant change in TEWL values. A total of 2398 lipids were detected by lipidomics analysis and 25 differential lipids were screened. Triradylglycerols (TGs), isoprenoids and hopanoids being the potential differential lipids. Among the lipids associated with the skin barrier, only monounsaturated fatty acids (MUFA) (p = 0.045) were significantly increased. This study revealed significant changes in SSL after blue light treatment for acne, suggesting that blue light exposure may cause changes in the relative lipid content and redistribution of lipid components, and that whether it damages the skin barrier requires further study.

Abstract
Simple Summary Photobiomodulation studies have reported that blue light irradiation induces the production of reactive oxygen species. We examined the effect of blue laser (405 nm) irradiation on ATP level in the skin and measured the types of reactive oxygen species and reactive nitrogen species. The decrease in the skin ATP level due to blue light irradiation may be caused by oxidative stress due to the generation of reactive oxygen species. These findings highlight the need to consider the effects on the skin when performing photobiomodulation treatment using blue light. Abstract Photobiomodulation studies have reported that blue light irradiation induces the production of reactive oxygen species. We investigated the effect of blue laser (405 nm) irradiation on the ATP levels in mouse skin and determined the types of reactive oxygen species and reactive nitrogen species using cultured mouse fibroblasts. Blue laser irradiation caused a decrease in the ATP level in the mouse skin and triggered the generation of superoxide anion and hypochlorous acid, whereas nitric oxide and peroxynitrite were not detected. Moreover, blue laser irradiation resulted in reduced cell viability. It is believed that the decrease in the skin ATP level due to blue light irradiation results from the increased levels of oxidative stress due to the generation of reactive oxygen species. This method of systematically measuring the levels of reactive oxygen species and reactive nitrogen species may be useful for understanding the effects of irradiation conditions.

[PMID: 34981580 DOI: 10.1111/phpp.12769] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 12/10/2021] [Accepted: 12/27/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Red and blue light therapies are safe and effective treatments for mild-to-moderate acne vulgaris. However, very few previous studies have directly compared the characteristics of these two methods. OBJECTIVE To compare the efficacy and side effects of red light (RL) and blue light (BL) for acne vulgaris and to assess these two therapies in different types of lesions. MATERIALS AND METHODS A total of 28 subjects with mild-to-moderate acne vulgaris were randomized into the RL group or the BL group. Subjects in each group received different light treatments, and they were followed up regularly until 2 weeks after the last treatment. The improvement rates of different types of acne lesions were compared between the 2 groups, as well as the incidence of adverse reactions. RESULTS At the 2-week follow-up, the average improvement rate of total acne lesions was 36.2% in the RL group and 30.7% in the BL group (p > .05). The average improvement rate of inflammatory and non-inflammatory lesions was 51.5% and 17.3% in the RL group, compared with 26.4% and 10.0% in the BL group (all p > .05). Treatment-related adverse reactions were observed distinctly in the BL group. CONCLUSIONS Red light and BL therapies have similar efficacy in mild-to-moderate acne vulgaris, especially for inflammatory lesions. RL had advantages with fewer adverse reactions compared with BL.

Abstract
Most modern sunscreens contain physical filters, which scatter the sunlight, increasing the photons' pathway in the upper stratum corneum. This effect can lead to a better efficacy of the UV filters and improve the diffuse reflection. However, the addition of nanosized inorganic UV filters reduces the antioxidant capacity of sunscreen formulations. Two cream formulations (F1, F2) which differ in the ingredient PEG75 Lanolin (F2), have been characterized for their radical protection factor (RPF) and their optical properties in vitro using electron paramagnetic resonance (EPR) spectroscopy and UV/VIS spectrometry. The RPF for PEG-75 Lanolin was also determined. Furthermore, their radical protection properties were analyzed on porcine skin ex vivo after visible light irradiation by EPR. The structure of each formulation in the skin surface was determined by reflectance confocal microscopy in vivo. The addition of lanolin increased the reflectance and reduced the transmittance for visible light, improving the scattering drastically. Besides, the antioxidant capacity was also increased for F2, something unpublished until now. F1 presented a lower scattering provided by starches. The sunscreens showed high scattering properties and antioxidant capacity, especially for F2, which presented the lowest radical formation in the skin model. These results are consistent with the RPF measurements where F2 has a higher RPF value (193 ± 3 × 1014 radicals/mg) than F1 (155 ± 4 × 1014 radicals/mg) and for PEG-75 Lanolin (37 ± 1 × 1014 radicals/mg). The combination of starches and PEG-75 Lanolin is the first solution to provide both, light scattering and antioxidant capacity, in sunscreens.

Abstract
Background: One of the most common dermatological conditions affecting most teenagers is acne. Phototherapy was described as a therapeutic modality with low-side effects of acne vulgaris (AV). Hence, we examined the effects of narrow band ultraviolet B (NBUVB) versus red light-emitting diodes (LEDs) on facial AV. Methods: Forty-five subjects suffering from facial AV mild to a moderate degree were randomly assigned into three groups, 15 subjects within every group. Group A was equipped to NBUVB with 311-313 nm and an initial dose of 250 mJ/cm2, thrice a week for 8 weeks, Group B was equipped red LED with wavelengths 633 ± 6 nm and power density of 80 mW/cm2, thrice a week for 8 weeks, whereas group C had received the only erythromycin as a control group. Outcome measures included measurement of acne lesion count and degree of severity. Measures at three-time intervals were assessed: baseline, 4 weeks (post I), and 8 weeks (post II). Results: Acne numeral findings revealed a significant variance among groups A, B, and C in favor of group A (p < 0.001). Notable improvements were observed across all three groups (p < 0.001). The degree of adjustment effects indicated a greater increase in group A in comparison with group B (p < 0.01), whereas no statistical variance was detected between group B and group C (p > 0.05). Conclusions: Both NBUVB and red LED were effective in acne treatment; NBUVB, however, revealed a highly efficient treatment than red LED in decreasing the acne lesions count and the improved degree of AV severity as measured by the global investigator's assessment scale. Clinical Trial Registration No. NCT04254601.

Abstract
BACKGROUND Low-level light therapy (LLLT) is a recent addition to the pantheon of light-based therapeutic interventions. The absorption of red/near-infrared light energy, a process termed "photobiomodulation," enhances mitochondrial ATP production, cell signaling, and growth factor synthesis, and attenuates oxidative stress. Photobiomodulation is now highly commercialized with devices marketed directly to the consumer. In the gray area between the commercial and therapeutic sectors, harnessing the clinical potential in reproducible and scientifically measurable ways remains challenging. OBJECTIVES The aim of this article was to summarize the clinical evidence for photobiomodulation and discuss the regulatory framework for this therapy. METHODS A review of the clinical literature pertaining to the use of LLLT for skin rejuvenation (facial rhytids and dyschromias), acne vulgaris, wound healing, body contouring, and androgenic alopecia was performed. RESULTS A reasonable body of clinical trial evidence exists to support the role of low-energy red/near-infrared light as a safe and effective method of skin rejuvenation, treatment of acne vulgaris and alopecia, and, especially, body contouring. Methodologic flaws, small patient cohorts, and industry funding mean there is ample scope to improve the quality of evidence. It remains unclear if light-emitting diode sources induce physiologic effects of compararable nature and magnitude to those of the laser-based systems used in most of the higher-quality studies. CONCLUSIONS LLLT is here to stay. However, its ubiquity and commercial success have outpaced empirical approaches on which solid clinical evidence is established. Thus, the challenge is to prove its therapeutic utility in retrospect. Well-designed, adequately powered, independent clinical trials will help us answer some of the unresolved questions and enable the potential of this therapy to be realized.

Abstract
Intense pulsed light (IPL) devices have been used in acne treatment in combination with conventional topical and oral medications. This study aimed to evaluate the efficacy and safety of IPL treatment using a dual-band filter (400-600 nm and 800-1200 nm) in facial acne vulgaris treatment. Twenty-three acne vulgaris patients were enrolled in this study. The patients were treated on both sides of the face. The treatments were performed in 2-week intervals for a total of five sessions. The final visit for the clinical evaluation was 2 weeks after the fifth treatment session. The mean number of papules, pustules, and comedones, and the melanin index, was significantly decreased at the final visit. However, sebum production and the erythema index showed no statistically significant differences after treatment. IPL treatment using a dual-band filter can be an alternative for patients who are unfit for systemic acne medication. It can also be used with conventional acne treatment for better treatment results.

Abstract
BACKGROUND AND OBJECTIVE Phototherapy for acne with a combination of blue and red light-emitting diodes (LEDs) appears to have excellent potential in treating inflammatory acne. However, a standard twice-weekly protocol administered 3 days apart may not be practical for patients. This study aims to seek the efficacy of LED treatment in moderate to severe acne, comparing between once and alternating twice-weekly regimens. STUDY DESIGN/MATERIALS AND METHODS Thirty subjects with moderate to severe acne, as defined by Burton's grading score, were recruited in the study. The subjects were randomly divided into two groups- one group received alternating blue (470 nm) and red (640 nm) light in two visits per week for 4 consecutive weeks, while the other group got blue and red light treatments consecutively on the same visit for 4 consecutive weeks. During the study period, conventional treatments were prohibited. Clinical assessments were performed by lesion counts and blinded comparative photographs before treatment and at 1, 4, and 8 weeks after the final treatment. RESULTS There was no statistically significant difference between once- and alternating twice-weekly regimens. Both regimens provided marked improvement only for inflammatory lesions. The median percentage of acne reduction was significantly demonstrated for 1 week after finishing the course of treatment and was sustained until the end of the study. There were no side effects noted throughout the study period. CONCLUSION LED therapy is safe and effective for treatment of inflammatory acne. The treatment outcomes of once and alternating twice-weekly regimens were comparable, hence, once-weekly treatment could be considered as an alternative choice for patient's convenience. Lasers Surg.

Abstract
BACKGROUND Rosacea is a chronic inflammatory disease of the skin, relatively more frequent in women over 30 with a low phototype and proven genetic predisposition. Although its etiology is unknown and possibly multifactorial, the immunological abnormality, associated with neurovascular dysregulation and triggering factors, are important elements in its pathophysiology, which lead to the main changes of inflammation, vasodilation, and angiogenesis that are responsible for the clinical manifestations. Despite the lack of cure, numerous therapeutic options are available for the different clinical presentations of the disease, with satisfactory responses. OBJECTIVE To reach a consensus, with recommendations from experts, on the therapeutic management of rosacea suitable to the Brazilian setting. METHODS The study was conducted by five specialized dermatologists from university centers, representatives of the different Brazilian regions, with experience in rosacea, who were appointed by the Brazilian Society of Dermatology. Based on the adapted DELPHI methodology, the experts contributed through an updated bibliographic review of the scientific evidence, combined with personal experiences. RESULTS The group of experts reached a consensus on the relevant aspects in the therapeutic management of rosacea, providing information on epidemiology, pathophysiology, triggering factors, clinical condition, classification, quality of life, and comorbidities. Consensus was defined as approval by at least 90% of the panel. CONCLUSION Despite the impossibility of cure, there are several therapeutic alternatives specific to each patient that provide excellent results, with chances of total improvement and long periods of remission, promoting a positive impact on quality of life. This consensus provides detailed guidance for clinical practice and therapeutic decisions in rosacea.

Abstract
BACKGROUND The purpose of this study was to elucidate why some potentially damaging and beneficial effects were obtained following blue light exposures on skin. MATERIALS AND METHODS Light-emitting diode (LED) devices containing 415 and 470 nm bulbs were used on normal human keratinocytes, skin biopsies and subjects with acne. Reactive oxygen species (ROS) evaluation was performed after a course of blue LED light exposures. A comparison between very small bandwidth centered at 415 nm and a combination of (415 + 470 nm) wavelengths was also carried out regarding the effects on ROS production. The effects on other targets such as opsin1 short wavelength (OPN1 SW) photoreceptor, fibrillin-1 dermal component, LL37 antimicrobial peptide and interleukin-8 (IL-8) proinflammatory cytokine were then explored. Finally, clinical pictures of acne signs were also investigated after blue LED exposures. RESULTS Dose dependent increases of ROS production were obtained on keratinocytes exposed to increasing 415 nm LED exposures. However, a ROS decreasing first phase was observed on keratinocytes exposed to 415 + 470 nm LED exposures. Moreover, comparing the same doses of 415 nm wavelength and (415 + 470 nm) wavelength combination, 415 nm alone is more damaging than the 415 + 470 nm exposures. In case of increase in ROS, decrease in OPN1 SW photoreceptor and fragmentation of fibrillin-1 dermal fiber were observed. When conditions of ROS decrease were experienced, an increase in LL37 antimicrobial peptide and a modulation of IL-8 inflammatory response were noted, suggesting improvement in acne signs. Clinical results confirmed the benefits on inflammatory lesions on subjects with acne. CONCLUSION Blue lights can induce beneficial and adverse effects, depending on the dose and on the spectrum width of the exposure.

Abstract
BACKGROUND The use of light-emitting diode (LED) in combination wavelength for facial rejuvenation has been previously reported. Nowadays, there has been a growing market for home-use cosmetic devices because of its low cost and convenience. AIMS To evaluate the efficacy and safety of home-use LED device on facial rejuvenation. METHODS This was a prospective split-face clinical trial with a total of 24 subjects, who presented with photo aging skin. All subjects were treated with the home-use LED device on the left side of their face, twice a week for 8 weeks. Primary outcomes measured in the study were the changes in the biophysical properties of the skin assessed with the following parameters: skin elasticity, skin hydration, texture, and wrinkles. Evaluations were done at baseline, 2-, 4-, 6-, and 8-week follow-up. Subjects' self-improvement scores and adverse reactions were also recorded. RESULTS All 24 subjects completed the study and attended all follow-up. Skin elasticity was significantly higher in the LED group compared to the control during the 6- and 8-week follow-up (P < .05). In the LED group, an image of the treated skin captured using Visioscan® showed improvement of the skin texture at 8-week follow-up. Majority of the subjects in the LED group scored good improvement on all follow-ups (37.5%, 41.7%, 58.3%, and 62.5%) when compared to the baseline. No adverse reactions or pain were recorded in the study. CONCLUSION The home-use LED device, with a combination wavelength of 637 and 854 nm, is safe and can be used as an adjunctive treatment for self-administered facial rejuvenation.

BACKGROUND 585 nm light-emitting diodes have been proven to suppress melanogenesis in melanocytes. However, whether LEDs will influence normal human epidermal keratinocytes (NHEKs) and paracrine effect of LEDs-irradiated NHEKs in melanogenesis remains unknown. OBJECTIVE To elucidate the possible mechanisms in vitro of anti-melanogenic activity of 585 nm LEDs on paracrine effect of NHEKs and its exosomes. METHODS NHEKs irradiated with different fluences of 585 nm LEDs were evaluated the cell viability by CCK8 assay. Irradiated medium of NHEKs was co-cultured with melanocytes. Melanin content, tyrosinase activity and melanogenic enzymes activities were detected. Exosomes from NHEKs medium were isolated and characterized by electron microscopy and nanoparticle tracking analysis. The expression changes of H19 and its encoded exosomal miR-675 were analyzed. RESULTS Irradiation with 585 nm LEDs from 0 J/cm2 to 20 J/cm2 had no cytotoxic effect on NHEKs. After co-cultured with irradiated medium of NHEKs, melanin content and tyrosinase activity were reduced and the melanogenic activities were downregulated on both mRNA and protein levels of microphthalmia-associated transcription factor (MITF), tyrosinase (TYR) and tyrosinase-related protein 1 (TRP-1). H19 and its derived exosomal miR-675 from NHEKs, which has been proven relevant to melanogenesis, were significantly upregulated after irradiation. Furthermore, H19 knockdown and miR-675 inhibition in NHEKs could attenuate the inhibition effect of 585 nm LEDs on melanogenesis. CONCLUSIONS This study demonstrated that 585 nm LEDs could inhibit melanogenesis via the up-regulation of H19 and its derived exosomal miR-675 from NHEKs, which was considered as a novel paracrine factor in regulating melanogenesis.

Abstract
Background Rosacea is a common inflammatory skin condition affecting approximately 5% of the world population. Therapeutic approaches to rosacea are focused on symptom suppression by means of anti-inflammatory agents. More recently, photodynamic therapy, especially light-emitting diodes, has been introduced as a valid alternative to conventional therapy. Case presentation In the present work, we reported the efficacy and safety of light-emitting diodes therapy combining blue (480 nm) and red (650 nm) light for the treatment of two patients with papulopustular rosacea: a 22-year-old Caucasian woman and a 68-year-old Caucasian man. Conclusions This kind of treatment could represent an effective, safer, and well-tolerated approach for the treatment of such conditions.

Abstract
Effective methods for managing the oral microbiome are necessary to ensure not only the oral but also the systemic health of a human body. The purpose of this study was to determine the sensitivity of four photosensitizers (PSs) to blue light in six representative oral bacterial species that cause intraoral diseases. The following six strains were investigated: Actinomyces israelii, Enterococcus faecium, Fusobacterium nucleatum, Lactobacillus gasseri, Streptococcus mutans, Veillonella parvula. PS stock solutions (1 mg/ml) were prepared by dissolving curcumin and protoporphyrin-IX in dimethyl sulfoxide, and resazurin and riboflavin in distilled water. The inoculation of 20 ml of a bacterial suspension cultured for 24 hours was mixed with 1,980 ml of each test solution, and then a light source was placed in front of the mixture. The irradiation wavelength was 405 nm and its applied energy was 25.3 J. The independent-samples t-test and one-way analysis of variance within groups were performed to compare the antibacterial effects in the four PSs. The antibacterial susceptibility when using different PSs and visible blue-light irradiation differed between the bacterial strains. Antibacterial photodynamic therapy that includes light exposure and PSs can be used to control the oral bacteria strains related to oral disease.

Abstract
PURPOSE OF REVIEW The goal of this review is to summarize the field to date and to discuss strengths and limitations of low-level laser (light) therapy (LLLT) for the future investigation as a treatment of inflammatory disease. RECENT FINDINGS LLLT is a promising therapeutic, particularly for those diseases of skin and joints because they are most accessible to treatment. Indeed, the known mechanisms of LLLT support its use for anti-inflammatory purposes, as well as stimulation of tissue growth and repair. Although the standard of care for the majority of inflammatory diseases is immunosuppressive agents such as corticosteroids with undesirable toxicities, LLLT offers a unique approach by being non-invasive and incurring minimal side effects. It is also relatively inexpensive and accessible and even has the possibility to be patient directed at home. There is evidence that LLLT is able to modulate the immune system at the skin and joint, and it has been shown to be efficacious in humans by affecting bacterial colonization as it may pertain to chronic rhinosinusitis. However, there is variability in the methods of laser application as well as a lack of evidence for laser type, dose-ranging studies, and wavelength selection that create barriers to the implementation of LLLT without further more rigorous and standardized study. The heterogeneity makes it difficult to draw strong conclusions about the efficacy of LLLT and its mechanisms.

Abstract
Background: Antirrhinum majus contains aurone with excellent antibacterial and antifungal activities. In addition, visible light activates the endogenous porphyrins of Propionibacterium acne, which results in bacterial death. Therefore, considering the above-mentioned facts, the aim of the present study was to prepare a topical herbal gel of A. majus hydroalcoholic extract and to evaluate its antiacne effects with or without blue light combination as an activator of the porphyrins. Materials and Methods: Antibacterial activity of the shoot or petal extracts was evaluated by disc diffusion method and the minimum inhibitory concentration (MIC) was calculated. Various gel formulations were developed by the Experimental Design software. The obtained gel formulations were prepared and tested for pharmaceutical parameters including organoleptic features, pH, viscosity, drug content, and release studies. Finally, the antibacterial activity was evaluated against (P. acnes) with or without blue light. Results: The MIC of the extracts showed to be 0.25 μg/ml. Evaluation of the gel formulation showed acceptable properties of the best formulation in comparison to a gel in the market. Pharmaceutical parameters were also in accordance with the standard parameters of the marketed gel. Furthermore, statistical analyses showed significant antibacterial effect for gel when compared to negative control. However, combination of blue light with gel did not show any significant difference on the observed antibacterial effect. Conclusion: Because of the statistically significant in vitro antiacne effects of the formulated gel, further clinical studies for evaluation of the healing effects of the prepared gel formulation on acne lesions must be performed.

Abstract
The purpose of the present scientific study was to analyze the effects of combined pulsed wave Photobiomodulation (PW PBM) and Curcumin on the microbial flora; in addition, the tensiometrical wounds properties for type one diabetes mellitus (TIDM) in an experimental animal model. TIDM induction was performed in thirty rats. In the entire animals, one full-thickness excision was implemented on their backs. Randomly, the divisions of rats into 5 groups took place. The primary group was considered as the control group and did not receive any treatment. The secondary group (placebo) received sesame oil by gastric gavage. The third group received PWPBM (890 nm, 80 Hz, 0.2 J/cm2). The fourth group received curcumin (40 mg/kg, which was dissolved in sesame oil) by gastric gavage. Eventually, the fifth group received PW PBM + curcumin. Precisely, on day 7, microbiological examinations, and on the 15th day microbiological and tensiometrical examinations were conducted. The data were analyzed by statistical tests. PW PBM, significantly exacerbated tensiometrical properties of the TIDM repairing wound. PW PBM, curcumin, and PWPBM + curcumin significantly decreased colony forming units compared to the control and the placebo groups indeed. It was remarkably attained that PW PBM significantly accelerated the process of wound healing in the STZ-induced TIDM. The PW PBM was statistically more compelling compared to the curcumin and PWPBM + curcumin. PW PBM, curcumin, and PWPBM + curcumin significantly decreased colony forming units compared to the control and placebo groups.

Abstract
BACKGROUND Melasma is a common hyperpigmentation skin disease on face. Light-emitting diode (LED) photomodulation (585nm) is reported to be effective for the treatment of melasma. However, whether and how LED photomodulation would influence melanogenesis of human epidermal melanocytes (HEMs) is unknown. OBJECTIVE To evaluate the effects of LED photomodulation (585nm) on melanogenesis in HEMs. METHODS HEMs were irradiated with fluences of 0, 5, 10 and 20J/cm2 585nm LED light. After 5-day treatment, cell viability was analyzed by CCK-8 assay, and apoptosis was assessed by Annexin V APC assay. Melanin content and tyrosinase activity were measured by spectrophotometer. Melanosome stage and autophagosomes were determined under transmission electron microscope (TEM). The formation of autophagic punctate structures was observed under confocal microscope. RT-PCR and western blotting were used to assess the expression of relative mRNA and protein levels. RESULTS Yellow light LED 585nm had no effects on HEMs cell viability and apoptosis. Treatment with LED 585nm from 5J/cm2 to 20J/cm2 inhibited melanosome maturation, decreased melanin content and tyrosinase activity. Inhibition was accompanied by the decreased expression of tyrosinase (TYR), tyrosinase-related protein-1 (TRP-1) and microphthalmia-associated transcription factor (MITF) on both mRNA and protein levels. Autophagosomes were observed under TEM. Autophagic punctate structures of microtubule-associated protein light chain 3 (LC3) proteins were induced by LED 585nm light. The configuration change of LC3 from LC3-I to LC3-II, and the degradation of p62 protein were observed after LED 585nm. Furthermore, we also revealed that the anti-melanogenic effect of LED 585nm photomodulation was reversed by 3-Methyladenine (3-MA), which inhibits autophagy by blocking autophagosome formation via the inhibition of type III Phosphatidylinositol 3-kinases (PI-3K). CONCLUSIONS Our finding demonstrated that LED photomodulation with 585nm wavelength suppressed melanin content in HEMs, and the effect was caused by its dose-dependent inhibition on melanogenesis and the induction of HEMs autophagy. This may provide new insights into the efficacy of LED photomodulation in the treatment of hyperpigmentation disorders.

Abstract
The objective of this study was to evaluate the effects of combination therapy with methylene blue (MB) assisted photodynamic therapy (PDT) and salicylic acid (SA) as chemo-therapy anticancer agent. The binding of salicylic acid to methylene blue was studied using spectrophotometric method. The results show the 1:2 complex formation between SA and MB. The binding constants and related Gibbs free energies o are obtained (Kb1=183.74, Kb2=38.13 and ∆Gb1°=12.92kJ·mol-1, ∆Gb2°=9.02kJ·mol-1). The spectrophotometric results show the improvement in solubilization and reduction prevention for SA and MB in the complex form. These results are in agreements with cellular experiments. The dark toxicity measurements represent the improve efficacy of chemotherapy using combination of SA and MB. The photodynamic therapy results (using red LED as light source (630nm; power density: 30mWcm-2)) show that the cancer cell killing efficiency of MB increases in the combination with SA due to reduction prevention and stabilization of monomeric form of MB.

Abstract
The use in dermatology of light-emitting diodes (LEDs) continues to be surrounded by controversy. This is due mainly to poor knowledge of the physicochemical phases of a wide range of devices that are difficult to compare to one another, and also to divergences between irrefutable published evidence either at the level of in vitro studies or at the cellular level, and discordant clinical results in a variety of different indications: rejuvenation, acne, wound healing, leg ulcers, and cutaneous inflammatory or autoimmune processes. Therapeutic LEDs can emit wavelengths ranging from the ultraviolet, through visible light, to the near infrared (247-1300 nm), but only certain bands have so far demonstrated any real value. We feel certain that if this article remains factual, then readers will have a different, or at least more nuanced, opinion concerning the use of such LED devices in dermatology.

Abstract
Background Automated skin lesion border examination and analysis techniques have become an important field of research for distinguishing malignant pigmented lesions from benign lesions. An abrupt pigment pattern cutoff at the periphery of a skin lesion is one of the most important dermoscopic features for detection of neoplastic behavior. In current clinical setting, the lesion is divided into a virtual pie with eight sections. Each section is examined by a dermatologist for abrupt cutoff and scored accordingly, which can be tedious and subjective. Methods This study introduces a novel approach to objectively quantify abruptness of pigment patterns along the lesion periphery. In the proposed approach, first, the skin lesion border is detected by the density based lesion border detection method. Second, the detected border is gradually scaled through vector operations. Then, along gradually scaled borders, pigment pattern homogeneities are calculated at different scales. Through this process, statistical texture features are extracted. Moreover, different color spaces are examined for the efficacy of texture analysis. Results The proposed method has been tested and validated on 100 (31 melanoma, 69 benign) dermoscopy images. Analyzed results indicate that proposed method is efficient on malignancy detection. More specifically, we obtained specificity of 0.96 and sensitivity of 0.86 for malignancy detection in a certain color space. The F-measure, harmonic mean of recall and precision, of the framework is reported as 0.87. Conclusions The use of texture homogeneity along the periphery of the lesion border is an effective method to detect malignancy of the skin lesion in dermoscopy images. Among different color spaces tested, RGB color space’s blue color channel is the most informative color channel to detect malignancy for skin lesions. That is followed by YCbCr color spaces Cr channel, and Cr is closely followed by the green color channel of RGB color space.

Abstract
BACKGROUND AND OBJECTIVE Photothermal therapy (PTT) has several applications in the areas of wound healing, pain management, bacterial infection control, and cancer treatment dependent on the temperature that is generated. PTT is often used exclusively with near infrared (NIR) light and most nanoparticles (NP) used for PTT are designed to absorb within one narrow range of wavelengths. We have developed a dual-wavelength photothermal therapy by capitalizing on the dual absorption of nanoparticles in the blue and NIR range. MATERIALS AND METHODS Our lab has previously developed NP based on the semiconducting, conjugated polymer poly[4,4-bis(2-ethylhexyl)-cyclopenta[2,1-b;3,4-b']dithiophene-2,6-diyl-alt-2,1,3-benzoselenadiazole-4,7-diyl] (PCPDTBSe). The NP have strong absorption in the blue and NIR regions. In this report, we have explored the heat generated by PCPDTBSe NP using simultaneous delivery of 450 and 800 nm light, either independently or together for photothermal ablation of mouse colorectal cancer cells. RESULTS The heat generation studies indicated that the use of either 450 or 800 nm wavelengths at the same fluences produced approximately the same temperature change of deionized water. Fluences of 114.6 and 229.2 J/cm2 , utilizing 450 or 800 nm light applied individually resulted in temperatures of 8-47°C above ambient temperature, leading to a 90% reduction in cell viability. Simultaneous stimulation of the PCPDTBSe NP with 450 and 800 nm light effectively doubles the effective power delivered, resulting in temperatures 18-63°C above ambient and 100% photothermal ablation of the colorectal cancer cells. CONCLUSION The results of this study demonstrate that PCPDTBSe polymer NP can be utilized as effective PTT agents by capitalizing on their dual absorption of both blue and NIR light. Lasers Surg.

Abstract
Acne is a very common non-infectious skin condition that is frequently treated in dermatological practices. Because acne is often chronic and may persist for years, safe and effective long-term maintenance therapy is often required. Given the increasing frequency of antibiotic-resistant bacteria and the gravity of the consequences of this trend, it behooves dermatologists to maximize use of non-antimicrobial therapy when treating acne. In this review of the literature we present data regarding the efficacy and appropriate use of non-antimicrobial treatments for acne. A variety of topical and oral treatment options exist that can be used in a step-wise manner according to the patients’ severity and therapeutic response. Non-antimicrobial treatments can be highly efficacious at controlling acne, especially when used as maintenance therapy. While antibiotics have a role in acne treatment, they should not be used as monotherapy, and lengthy courses of antibiotic use are discouraged.

Abstract
BACKGROUND Aggressive, or even minimally aggressive, aesthetic interventions are almost inevitably followed by such events as discomfort, erythema, edema and hematoma formation which could lengthen patient downtime and represent a major problem to the surgeon. Recently, low level light therapy with light-emitting diodes (LED-LLLT) at 830 nm has attracted attention in wound healing indications for its anti-inflammatory effects and control of erythema, edema and bruising. RATIONALE The wavelength of 830 nm offers deep penetration into living biological tissue, including bone. A new-generation of 830 nm LEDs, based on those developed in the NASA Space Medicine Laboratory, has enabled the construction of planar array-based LED-LLLT systems with clinically useful irradiances. Irradiation with 830 nm energy has been shown in vitro and in vivo to increase the action potential of epidermal and dermal cells significantly. The response of the inflammatory stage cells is enhanced both in terms of function and trophic factor release, and fibroblasts demonstrate superior collagenesis and elastinogenesis. CONCLUSIONS A growing body of clinical evidence is showing that applying 830 nm LED-LLLT as soon as possible post-procedure, both invasive and noninvasive, successfully hastens the resolution of sequelae associated with patient downtime in addition to significantly speeding up frank wound healing. This article reviews that evidence, and attempts to show that 830 nm LED-LLLT delivers swift resolution of postoperative sequelae, minimizes downtime and enhances patient satisfaction.
