Abstract
Autofluorophores are endogenous fluorescent compounds that naturally occur in the intra and extracellular spaces of all tissues and organs. Most have vital biological functions - like the metabolic cofactors NAD(P)H and FAD+, as well as the structural protein collagen. Others are considered to be waste products - like lipofuscin and advanced glycation end products - which accumulate with age and are associated with cellular dysfunction. Due to their natural fluorescence, these materials have great utility for enabling non-invasive, label-free assays with direct ties to biological function. Numerous technologies, with different advantages and drawbacks, are applied to their assessment, including fluorescence lifetime imaging microscopy, hyperspectral microscopy, and flow cytometry. Here, the applications of label-free autofluorophore assessment are reviewed for clinical and health-research applications, with specific attention to biomaterials, disease detection, surgical guidance, treatment monitoring, and tissue assessment - fields that greatly benefit from non-invasive methodologies capable of continuous, in vivo characterization.

Abstract
Acne is a long-lasting inflammatory skin condition that impacts the sebaceous units of the hair follicles, affecting around 85-90% of the population. Due to the potential for permanent facial scarring and negative social consequences, as well as the limitations of conventional medications like drug resistance and difficulties following treatment plans, it's crucial to investigate non-pharmacological options for treating acne, among which radiofrequency(RF) shows distinct superiority. To assess the impact of RF in the management of acne vulgaris, we conducted a thorough examination of scientific literature (including clinical trials and scientific reviews) through electronic databases like MEDLINE and PubMed. Our analysis indicates that RF could be a viable substitute for acne treatment due to its notable effectiveness and minimal adverse effects.

Abstract
Background: Photodynamic therapy (PDT) of cancer has been limited by the poor solubility of most photosensitizers, use of high drug dosages, and the pH difference between the tumor tissue microenvironment (slightly acidic) and the bloodstream. These affect cellular uptake, selectivity and singlet oxygen generation. Materials & methods: We formulated Photinia glabra-green synthesized zinc oxide-protoporphyrin IX (PG-ZnO-PP) nanoconjugates by conjugating the ZnO nanoparticles enriched with amino groups and PP. Results: PG-ZnO-PP nanoconjugates showed higher rate of reactive oxygen species generation, improved cellular uptake in the acidic pH and lower IC50 toward Eca-109 cells for PDT. Conclusion: PG-ZnO-PP nanoconjugates are a potential solution to reducing drug dosage of PP through improved drug uptake, for enhanced targetability and reduced skin photosensitivity with improved PDT efficacy.

Abstract
PURPOSE Fractional microneedle radiofrequency (FMR) systems are used to treat inflammatory acne and scarring. Nonetheless, few controlled studies have combined this treatment with the traditional ablative fractional laser (AFL). We aimed to assess the safety and efficacy of the combination of FMR and AFL versus AFL alone in treating acne and acne scars. MATERIALS AND METHODS In this 20-week, randomized, split-face study, 23 Korean patients with facial acne and acne scars underwent FMR and AFL treatments. One half of each patient's face was randomly assigned to receive FMR+AFL, whereas the other half received AFL alone. Treatments were administered in three consecutive sessions at 4-week intervals. This study investigated the severity of inflammatory acne, acne scars, individual lesion counts, depressed scar volumes, as well as patient and physician satisfaction. In addition, five patients underwent skin biopsy, and sebum output was measured. RESULTS The FMR+AFL treatment demonstrated superior efficacy compared to AFL alone in terms of inflammatory acne and acne scar grading, lesion counts, and subjective satisfaction. The side effects were minimal and well-tolerated in both groups. Immunohistochemical findings from skin biopsy samples revealed that the application of FMR+AFL could induce an inhibitory effect on sebum secretion at the molecular level. CONCLUSION FMR combined with AFL is a well-tolerated and effective treatment modality for inflammatory acne and acne scarring.

Abstract
Photodynamic therapy (PDT) is a photochemotherapy based on local application of a photosensitive compound and subsequent exposure to a light source of adequate wavelength. It is a non-invasive therapeutic procedure widely used in oncodermatology for treatment of numerous skin cancers, but in the last years its use has been gradually extended to an increasing list of skin diseases of both infectious and inflammatory nature. Although PDT is proven as a safe and effective therapeutic option in adults, its use is not well standardized in the pediatric population. In this review, we will focus on clinical applications, mechanisms of action, protocols, and adverse events in children and adolescents. Most of pediatric experiences concerned treatment of skin cancers in Gorlin syndrome and xeroderma pigmentosum, acne vulgaris, and viral warts, but other applications emerged, such as cutaneous lymphoma and pseudo-lymphomas, necrobiosis lipoidica, hidradenitis suppurativa, dissecting cellulitis, leishmaniasis, angiofibromas, verrucous epidermal nevus, and linear porokeratosis. In these pediatric diseases, PDT appeared as an effective therapeutic alternative. The results on vitiligo were limited and not fully encouraging. Although highly versatile, PDT is not a therapy for all skin diseases, and a deeper knowledge of its mechanisms of action is required to better define its spectrum of action and safety in pediatric patients.

Abstract
Acne is one of the commonest problems of adolescence with almost half of the patients experiencing persistence into adulthood. Pulsed dye lasers (PDL) with wavelengths of 585 and 595 nm targeting hemoglobin have been used for the treatment of this condition and its sequelae. Recent introduction of PDL with a higher wavelength of 1319 nm has been reported to offer some benefit to acne patients. We reviewed the literature on the use of 595-nm and 1319-nm PDL in the management of acne. A PubMed literature search for search terms "pulsed dye laser," "acne laser therapy," "light therapy for acne," "595 nm and acne," "1319 nm and acne" was done. Studies, series and case reports were included. These lasers were compared to other lasers and light sources such as 532-nm Potassium Titanyl Phosphate laser, 585-nm PDLs, 1450-nm diode laser, 1540-nm erbium glass laser, intense-pulsed light (IPL), photodynamic therapy, red and blue light and short-pulsed 1064 nm laser utilized in acne management regarding their efficacy. Improvement in acne grading, scale severity or reduction in lesion count indicated substantial efficacy of the laser system utilized.

Abstract
BACKGROUND The need for noninvasive methods in treatment of cutaneous disease has continued to evolve exponentially. Amidst the search for technologies, radiofrequency (RF) has proven efficacious in numerous skin disease processes. Although RF is well known for its cosmetic utility, its mechanism is valued in the treatment of many noncosmetic cutaneous conditions of various etiologies. OBJECTIVE To identify and describe studies in which RF was used to treat noncosmetic skin conditions and to explore the potential of this modality for further application in dermatologic diseases. MATERIALS AND METHODS The PubMed database was used to find relevant articles. RESULTS This search strategy yielded 54 articles that met the eligibility criteria. Noncosmetic indications discussed in these articles include varicose veins (n = 10,550), lymphangioma circumscriptum (n = 72), cutaneous neoplasms (n = 42), cutaneous leishmaniasis (n = 743), acne and acne scarring (n = 158), non-acne scarring (n = 43), primary axillary hyperhidrosis (n = 76), and acute and chronic wounds (n = 94). CONCLUSION Treatment with RF is an effective, generally noninvasive modality with a relatively short postprocedure recovery time and little potential for severe adverse effects in the treatment of several cutaneous conditions. Further clinical studies would prove useful to assess the efficacy and cost-effectiveness of this treatment.

Abstract
Acne vulgaris is one of the most common skin diseases affecting young people. Intense pulsed light (IPL) has become a well-recognized method in the treatment of acne vulgaris. We aim evaluate the clinical efficacy and safety of a novel IPL filter at wavelength of 400-600 nm and 800-1,200 nm in the treatment of inflammatory acne lesions. Twenty-one patients with Pillsbury I-III facial acne vulgaris between July 2017 and January 2018 were enrolled in this prospective clinical study. Five sessions of IPL treatment were administered to the subjects at 4-week interval. Final assessment was performed 1 month after the final treatment. One month posttreatment, over 75% subjects exhibited excellent or good response. Of the Pillsbury I-II patients, the effective rate reached 88.24%. The inflammatory lesions were dramatically decreased (25.23 ± 2.76 versus 14.01 ± 1.98) and statistically evident (P = .031). According to Hayashi assessment of acne severity, there was a significant improvement at follow-up visit (P = .022). Moreover, patients reported significant improvements in self-evaluation. The novel IPL filter at wavelength of 400-600 nm and 800-1,200 nm provides an effective option to treatment of inflammatory acne lesions, especially for Pillsbury I-II acne patients, with minimal reversible side effects, such as transient post-inflammatory pigmentation.

Abstract
BACKGROUND While device-based acne treatments are widely applied for patients not tolerating conventional medications, related controlled studies have been still limited. Recently, non-ablative 1450-nm diode laser (DL) and fractional microneedling radiofrequency (FMR) have been effectively used for acne, in addition to well-recognized dermal remodelling effects. OBJECTIVE To compare the clinical course of acne treatment between DL and FMR. METHODS Twenty-five Korean patients with mild-to-moderate facial acne completed treatments with DL and FMR through a 20-week, randomized split-face study. One randomly assigned half side of each patient's face received DL and the other side by FMR. Treatments were scheduled to receive three consecutive sessions at 4-week intervals. Objective assessments including revised Leeds grades, lesion counts, sebum output measurements, and patients' subjective satisfaction were investigated. RESULTS Both DL and FMR demonstrated steady improvement of acne and seborrhoea during treatment sessions. While results between two devices were similar during treatment sessions, FMR was superior to DL in the 12-week follow-up. Patients' subjective assessments for seborrhoea improvement were similar between two devices, while those for acne, skin texture, and acne scars were more satisfactory for FMR. For safety profile, no significant difference was observed between two regimens, while mild postinflammatory hyperpigmentation was observed only in DL side. CONCLUSION Both DL and FMR demonstrated efficacies for acne and seborrhoea, with reasonable safety profile. FMR was more effective than DL for the long-term maintenance, and subjective assessments for texture and scar improvements. Therefore, a few sessions of these devices would be a viable option for acne treatments.

Abstract
The clinical features of photoaging include: skin texture changes, laxity, rhytides, pigmentary changes, and vascular changes such as erythema and telangiectasias. In order to meet patients' increasing demands for improving all aspects of photoaging at one office visit, employing a multi-modality treatment for all aspects of photoaging has become increasingly desirable for the physician and patient alike. We examine a novel device that employs bipolar radiofrequency (RF), intense pulsed light (IPL), and infrared diode laser. These laser and light source treatments are performed sequentially. This study aims to evaluate the clinical efficacy and safety of this device (i.e., ELOS Triniti™). Twenty-six subjects received four ELOS Triniti™ treatments at 1-month intervals. They were followed up 1, 3, and 6 months after completing the treatments. Two blinded dermatologists used a comprehensive grading scale to evaluate the degree of the photoaging in terms of rhytides, laxity, dyschromia, erythema, telangiectasias, and texture. Subjects used a 0-10 grading scale for self-assessment of photoaging. Additionally, we measured the Erythema Index (EI), Melanin Index (MI), transepidermal water loss scores (TEWL), stratum corneum moisture scores (SC), and dermis moisture scores (D) before treatment and 1, 3, and 6 months after treatment. There was a statistically significant improvement in all five aspects of the comprehensive grading scale. Overall, it had excellent efficacy for improving erythema, telangiectasias, and skin texture. It also had a relatively long effect on improving skin laxity; however, it had only a limited ability to improve rhytides and dyschromia. It can mildly to moderately improve the global photoaging. This global effect can be noted 1 month after treatment and becomes most clinically apparent 3 months after treatment. This is maintained at least 6 months after treatment. MI index and SC and D values increased while EI index and TEWL values decreased after the treatment. The subjects' self-assessment improved by 2.7 ± 1.2 points. The overall satisfaction rate was 88%. The degree of pain measured 2.5 ± 1.9 points on average. There was no downtime and no severe side effects reported. The sequential implementation of bipolar radiofrequency based optical combination devices (IPL, IR, diode laser) is effective and safe for global facial photoaging.

Abstract
Mesotherapy, microneedling, and chemical peels are minimally invasive techniques used to combat facial aging. Chemical peeling is one of the oldest methods of facial rejuvenation. By using different chemicals in various combinations, strengths, and application techniques, plastic surgeons can tailor a patient's treatment for optimal, safe, and consistent results. Mesotherapy and microneedling have emerged in the plastic surgery literature with increasingly complex indications. Both techniques have increased in popularity although research into efficacy and long-term results is lagging. With a thorough understanding of patients and the modalities available, plastic surgeons can use the appropriate minimally invasive technique to provide patients with desired skin changes.

Abstract
BACKGROUND Recently, much interest has been generated in the use of intense pulsed light (IPL) sources in the treatment of various skin conditions. However, the underlying mechanism for its therapeutic action has not been elucidated. OBJECTIVE To investigate the effect of IPL on the in vivo expression of transforming growth factor beta1 (TGF-β1) and on the immunolocalization of Smad3 in biopsies obtained from perilesional skin in patients with mild-to-moderate inflammatory acne vulgaris. METHODS Biopsies obtained from 20 patients with inflammatory acne vulgaris at baseline (B1) and post-IPL treatment (B2 = 48 h after first treatment and B3 = 1 week after final treatment) were immunohistochemically analyzed to determine the expression of TGF-β1 and the immunolocalization of Smad3. Digital images were semiquantitatively assessed using image analysis software. RESULTS Intense pulsed light elicited a consistent increase in epidermal TGF-β1 expression (B2 vs. B1: P = 0.004 and B3 vs. B1: P = 0.007). Furthermore, it resulted in enhanced nuclear immunolocalization of Smad3 (B2 vs. B1: epidermis, P = 0.000055 and dermis, P = 0.014; B3 vs. B1: epidermis, P = 0.00024 and dermis, P = 0.008). CONCLUSION Intense pulsed light upregulates TGF-β1/Smad3 signaling in perilesional skin obtained from patients with mild-to-moderate inflammatory acne vulgaris. Further experiments on lesional skin and downstream effects are warranted to determine whether it may play a role in IPL-induced resolution of acne vulgaris.

Abstract
BACKGROUND A number of lasers and light-based devices have been reported as promising treatment options for acne vulgaris. OBJECTIVE To evaluate the efficacy and safety of fractional microneedle radiofrequency (MRF) device treatment compared to CO(2) fractional laser system (FS) for the treatment of acne vulgaris. METHODS Twenty healthy subjects underwent full-face treatment for acne vulgaris with CO(2) FS and MRF device. For each subject, two passes of CO(2) FS with a pulse energy setting of 80 mJ and a density of 100 spots/cm(2) were used on one side, and two passes of MRF device with a intensity of 8, density of 25 MTZ/cm(2), and a depth of 1.5-2.5 mm were used on the other. Patients were evaluated 3 months postoperatively and were also photographed. RESULTS Most of the patients improved based on clinical and photographic assessments 3 months after the treatment. No significant differences in physician-measured parameters, patient ratings, or intraoperative pain ratings were found, although downtime was significantly longer for the CO(2) FS treated side. CONCLUSIONS MRF device and CO(2) FS can be used for acne vulgaris patients and MRF device is more convenient than CO(2) FS because of its short downtime.

Abstract
Traditional medical treatments for acne vulgaris include a variety of topical and oral medications. The combination of poor compliance, lack of durable remission, and potential side effects are common drawbacks to these treatments. The use of lasers and light devices has increased dramatically in recent years due to the overall ease of treatment, predictable clinical efficacy, and minimal adverse effects. A variety of light and laser devices has been used for the treatment of acne, including the potassium titanyl phosphate (KTP) laser, the 585- and 595-nm pulsed dye lasers, the 1450-nm diode laser, radiofrequency devices, intense pulsed light sources, low-intensity light treatment, and photodynamic therapy using 5-aminolevulinic acid and indocyanine green. These devices are thought to target underlying pathogenic factors such as Propionibacterium acnes colonization, increased sebaceous gland activity, and the cutaneous inflammatory response. Lasers in particular also have a central role in the management of acne scarring, which tends to be refractory to medical therapies. Fractional photothermolysis, the 1450-nm diode laser, and pulsed dye lasers have been used in the nonablative treatment of acne scars with significant success. In this article, we review the current status of light- and laser-based treatment of acne and related conditions and briefly review the use of lasers for the treatment of acne scarring.

Abstract
BACKGROUND/PURPOSE Conventional treatment methods for acne vulgaris have various side effects such as the development of bacterial resistance, phototoxicity, vertigo, gastro-intestinal problems, and drug eruptions. To minimize such side effects, light and thermal methods have been alternately suggested. This study characterized a new acne vulgaris treatment device (AVTD) that combines both light and thermal methods and evaluated its clinical efficacy. METHODS We characterized the thermal and light properties of the AVTD itself and evaluated its thermal characteristics in ex vivo porcine skin samples. The Arrhenius equation was used to calculate the skin thermal injury coefficient to confirm the skin safety of the AVTD. Finally, the clinical efficacy of the AVDT was evaluated by analyzing cross-polarization and erythema index images, which were obtained from 13 volunteers undergoing treatment with the AVTD. RESULTS The temperature of the AVTD itself was maintained at 49.1 °C on the tip and 39.7 °C in the porcine skin samples. The peak intensity of the light-emitting diode (LED) light was observed at 468 nm. The skin safety of the AVTD was confirmed and 84.2% of the volunteers presented positive treatment results. CONCLUSION The treatment of acne using the AVTD resulted in a high treatment rate in a clinical study, minimizing side effects. On the basis of these results, we can be sure that the AVTD may be effectively used for the treatment of acne vulgaris.

Abstract
BACKGROUND Simple procedural treatments such as comedone extraction and intralesional steroids have been utilized for many years as adjunctive therapy for acne. In the past 5 years, new technologies and procedures have become available that present new options for the treatment of acne. OBJECTIVES The objective was to review, summarize, and evaluate the key studies of procedural therapies for the treatment of acne as well as place them in perspective with current clinical practice. METHODS Studies selected for evaluation had at least 10 patients and clear statements of purpose, acne severity, patient selection, follow-up evaluations, previous and concurrent medications, treatment parameters, methods for evaluating results, and adverse effects. All studies were complete and published (in English) in peer-reviewed journals. RESULTS AND CONCLUSIONS Earlier procedural therapies were adjunctive to medical therapy, such as intralesional steroids, chemical peels, and microdermabrasion. Newer methods include radiofrequency, light or laser, and photodynamic therapy that represent treatment alternatives for systemic medications. Still early in their development, these new procedures provide an important, novel set of options for the treatment of acne. The most developed and studied therapies are blue or blue/red light combinations, 1,450-nm diode laser, and photodynamic therapy with 5-aminolevulinic acid or indocyanine green. Review of the literature of more up-to-date physical procedures provides a starting point for physicians seeking to treat their acne patients safely and effectively with these new methods.

Abstract
BACKGROUND AND OBJECTIVES Blue light is effective for acne treatment, inducing photodynamic destruction of Propionibacterium acnes (P. acnes). This study was designed to investigate the efficacy of combined blue and red light-emitting diode (LED) phototherapy for acne vulgaris. MATERIALS AND METHODS Twenty-four patients with mild to moderately severe facial acne were treated with quasimonochromatic LED devices, alternating blue (415 nm) and red (633 nm) light. The treatment was performed twice a week for 4 weeks. Objective assays of the skin condition were carried out before and after treatment at each treatment session. Clinical assessments were conducted before treatment, after the 2nd, 4th, and 6th treatment sessions and at 2, 4, and 8 weeks after the final treatment by grading and lesion counting. RESULTS The final mean percentage improvements in non-inflammatory and inflammatory lesions were 34.28% and 77.93%, respectively. Instrumental measurements indicated that the melanin levels significantly decreased after treatment. Brightened skin tone and improved skin texture were spontaneously reported by 14 patients. CONCLUSION Blue and red light combination LED phototherapy is an effective, safe and non-painful treatment for mild to moderately severe acne vulgaris, particularly for papulopustular acne lesions.
