Abstract
In the last years, hair removal has been one of the most common treatments performed for aesthetic purposes, especially in women. Nevertheless, even if it is less popular, the demand within men population has risen. The study aimed to assess the acceptability of the diode 810 nm treatment for hair removal on the back and chest area in men thanks to the speed of treatment and the absence of undesirable effects. For this study, 20 patients were treated for hair removal. They were men with a mean age of 30.5 (±7.3). They underwent 4 treatment sessions at 40-day intervals on the trunk (chest and back area). Patients ranged between a Fitzpatrick phototype I (20%, 4/20) to IV (15%, 3/20) (40% were type II and 25% type III). Moreover, patients were asked to report pain intensity sensation with a visual analogue scale. Overall, in the study population, a hair reduction of 80.6% (±2.8) was registered in the treated areas. The device described in this study was demonstrated to be highly efficient in extended body areas and on difficult-to-treat hair follicles like on the back and chest in the men population.

Abstract
BACKGROUND With light-assisted hair removal becoming widely used, reports of adverse effects are increasing. OBJECTIVE To review all the reported optical incidents and cutaneous complications of laser or intense pulse light-assisted hair removal. METHODS A PubMed database systematic search was performed to identify studies reporting such adverse events before July 2022 using the Mesh terms "adverse effects" AND "hair removal" AND ("laser" OR "intense pulse light"). RESULTS Altogether, 358 references were identified. After excluding duplicates, unrelated articles, guidelines, and conference abstracts, then adding references from studies bibliography, 104 publications were included. Ocular incidents consisted of anterior uveitis, iritis and iris atrophy, pupillary distortion, posterior synechiae, anterior chamber pigment, and cataracts in the anterior subcapsular region. Cutaneous complications consisted of pain, burns, folliculitis, leukotrichia, paradoxical hypertrichosis, pigmentary changes, changes in nevi, pili bigemini, herpes infection, hyperhidrosis, bromhidrosis, Fox-Fordyce disease, and frostbite from the cooling system. They were mostly correlated to skin type and body area as well as to light device and set parameters. Intense pulse light devices were found to be less painful than alexandrite laser, yet more painful than diode laser; Nd:YAG laser had the highest pain score. CONCLUSION Optical incidents can be systematically avoided. Cutaneous complications are usually related to professional errors and patient characteristics. Better knowledge of laser physics and adequate training of laser operators are key recommendations to avoid undesirable side effects. Safety recommendations help prevent most of the reported complications.

Abstract
This study aimed to investigate the safety and efficacy of depilation with intense pulsed light (IPL) in congenital microtia patients during their reconstruction treatment. The hairy skin was treated with the M22TM system (Lumenis, German) using a filter of 695 to 1200 mm. A contact prob with a window of 15 cm × 35 mm or 8 cm × 15 mm was used at a radiant setting of 14 to 15 J/cm2 in the non-expander group and 13 to 14 J/cm2 in the expander group, both in a single pulse mode. The efficiency index of hair removal was classified based on the percentage of hair density reduction as excellent (>75%), good (50-75%), fair (25-50%), poor (<25%). The depilation effect was compared between the 2 groups, and any adverse effects were evaluated. A total of 159 patients were included, with 93 patients in the expander group and 66 in the non-expander group. The reduction of the hair density in the expander group after 3 treatments was higher than that in the non-expander group [82.98 (73.47-89.09)% vs 77.84 (71.50-85.34)%; P < .05, Wilcoxon rank-sum test], as well as the efficiency [excellent cases 68 (73.12%) vs 37 (56.06%); P < .05, Chi-square test]. Four cases of folliculitis, 3 cases of blisters, and no instance of expander exposure and cartilage absorption were observed in this study. Hair removal with IPL is a safe and effective photo-epilation method during all stages of ear reconstruction using tissue expander. Depilation in the skin expansion period resulted in better outcomes after 3 treatments, although after 5 treatments no difference between the 2 groups was observed.

Abstract
BACKGROUND Laser hair removal is an increasingly prevalent trend of cosmetic procedures. The purpose of this study was to assess the effectiveness of hair reduction among several types of laser interventions. METHODS The selected studies searched in PubMed and EMBASE were assessed for quality of evidence, and extracted data on absolute hair count and hair reduction rate. Qualitative data were synthesized using standardized mean difference (SMD) in frequentist network meta-analysis because various measurement units were used among selected studies. Inconsistency and small study effects were examined by design-by-treatment interaction model and comparison-adjusted funnel plot. RESULTS A total of 13 randomized controlled trials (RCTs) (n = 652) were contributed to network meta-analysis. Pooled results revealed that diode laser showed significantly lower absolute hair count within three-month (SMD = -13.21, 95% confidence interval [CI]: -22.25 to -4.17) and around six months follow-up (SMD = -11.01, 95% CI: -18.24 to -3.77) as compared with those in control group, but no significant difference among laser interventions. All side effects observed were transient without leaving any permanent scars. CONCLUSION Eliminating unwanted hair with lasers or intense pulsed light is safe and effective; however, which type of intervention is more beneficial in the long-term process should be studied with a longer follow-up time.

Abstract
Background and Objectives: Hair removal is a common aesthetic concern for patients referred to dermatologists and aesthetic physicians. Lasers and lights are one of the mainstays in the management of this condition. Among these devices, intense pulsed lights (IPLs) are broadly used in order to reduce the number and width of the hair present. Currently used techniques are associated with a high risk of side effects, such as hyper or hypopigmentation. Materials and Methods: Thirty patients seeking hair removal in one or more body areas with skin phototypes 1 to 4 were recruited to perform this study. All areas to be treated were divided into two equal regions; one side was treated with the standard IPL hair removal procedure, while the other was treated with a new “in-motion” IPL technology. Results and hair removal rates were evaluated six months after the last treatment. Results: Out of the 30 patients treated, all patients experienced hair reduction. No statistically significant difference in hair removal was noted among the two sides. A statistically significant reduction in pain during the procedure was observed in the side treated with the “in-motion” technique. Conclusions: Traditional and “in-motion” IPL techniques have similar results in hair removal; the “in-motion” technology seems to guarantee a better safety profile than the traditional technique, as well as maintains the same results over time and a faster treatment time. A more extensive clinical study will be necessary to confirm our study’s results.

Abstract
BACKGROUND Laser hair removal is one of the most popular aesthetic procedures. AIMS The study aimed to assess the efficacy and safety of a novel applicator combining three wavelengths (1064 nm, 810 nm, and 755 nm) for hair removal. PATIENTS/METHODS This prospective study included a four-session hair removal treatment with three wavelengths combined and emitted simultaneously using an in-motion technique. Patients were treated in eight-week intervals between each session and a follow-up of 3 months. RESULTS Twenty-two men (mean age 41.5 years, SD = 6.1) were included: two (9.1%) Fitzpatrick skin type II, 19 (86.4%) type III, and one (4.5%) type IV. Treated areas were two abdomens (14%), fourteen backs (64%), and five thoraxes (23%). Hair characteristics were evaluated with a dermatoscopic imaging system. Three months after the last session, the mean decrease in the hair count was of 75.6% (SD 5.9) (p < 0.0001), in hair density of 75.6% (SD 5.9) (p < 0.0001), in the terminal hair number of 60.1% (SD 55.0) (p < 0.0001), and in the vellus hair number of 39.7% (SD 72.9) (p = 0.0001). CONCLUSION The combined three different wavelengths in a single device provided a wide range of absorption and penetration, allowing for a safe and effective treatment.

Abstract
Unwanted facial hair growth is a common esthetic problem. Laser hair removal has emerged as a leading treatment option for long-term depilation. The theory of selective photothermolysis has revolutionized laser hair removal in that it is effective and safe, when operated by sufficiently trained and experienced professionals. Long-pulsed ruby (694 nm), long-pulsed alexandrite (755 nm), diode (800-980 nm), and long-pulsed Nd: YAG (1064) are commercially available laser devices for hair removal most widely studied. The authors wish to share the efficacy and safety of intense pulse light therapy for permanent facial hair reduction in Indian population.

Abstract
Background: Various methods exist to manage unwanted hair in low hairline microtia. We present our 10-year experience that compares the two procedures toward all degrees of low hairline microtia. Methods: The tongue-shaped split-thickness skin graft procedure (modified Chen's procedure) and the modified Nagata procedure were used for ear reconstruction in 42 microtia patients with three degrees of low hairlines from 2010 to 2020. Hair follicles in the low hairline area were removed free-hand, and the removed area was replaced with extended temporoparietal fascia (TPF) flap during the ear elevation. The satisfaction score and the clearance percentages of the hair were used as outcome measures. Results: There was no significant difference in satisfaction scores and the hair clearance percentages of hair between two procedures (p > 0.05) and among three degrees of low hairline (p > 0.05), respectively. Although the complication rate showed no significant difference, the major types of complication in modified Chen's procedure was fluid accumulation (9.52%), whereas in modified Nagata procedure was hypertrophic scar (4.76%). Conclusion: Patients with low hairlines can be treated using two different microtia reconstruction techniques to limit hair growth on the new ear. The rib graft construct is covered by a TPF flap, which is then grafted with an ultrathin skin graft and shows benefit in this review of our 10-year experience.

Abstract
The evolution of modern laser and light-based systems has mirrored the demand for clinically effective treatments and the need for safer technologies with reduced postoperative recovery, side effects, and complications. With each new generation of lasers, more selective tissue destruction can be achieved with reduced unwanted sequelae. Patient selection and preparation, operator technique, and expeditious recognition and management of post-treatment side effects are paramount in avoiding complications and patient dissatisfaction. An overview of important variables to consider for dermatologic laser treatments are presented in order to provide a framework to reduce the severity and duration of possible post-treatment side effects and complications.

Abstract
Clobetasol propionate (CLO) is a potent glucocorticoid used to treat inflammation-based skin, scalp, and hair disorders. In such conditions, hair follicles (HF) are not only the target site but can also act as drug reservoirs when certain formulations are topically applied. Recently, we have demonstrated nanostructured lipid carriers (NLC) containing CLO presenting epidermal-targeting potential. Here, the focus was evaluating the HF uptake provided by such nanoparticles in comparison to a commercial cream and investigating the influence of different physical stimuli [i.e., infrared (IR) irradiation (with and without metallic nanoparticles-MNP), ultrasound (US) (with and without vibration) and mechanical massage] on their follicular targeting potential. Nanosystems presented sizes around 180 nm (PdI < 0.2) and negative zeta potential. The formulation did not alter skin water loss measurements and was stable for at least 30 days at 5 °C. Nanoparticles released the drug in a sustained fashion for more than 3 days and increased passively about 40 times CLO follicular uptake compared to the commercial cream. Confocal images confirmed the enhanced follicular delivery. On the one hand, NLC application followed by IR for heat generation showed no benefit in terms of HF targeting even at higher temperatures generated by metallic nanoparticle heating. On the other hand, upon US treatment, CLO retention was significantly increased in deeper skin layers. The addition of mechanical vibration to the US treatment led to higher follicular accumulation compared to passive exposure to NLC without stimuli. However, from all evaluated stimuli, manual massage presented the highest follicular targeting potential, driving more than double the amount of CLO into the HF than NLC passive application. In conclusion, NLC showed great potential for delivering CLO to HF, and a simple massage was capable of doubling follicular retention.

Abstract
Genital rejuvenation is applicable not only to women (vaginal rejuvenation) but also to men (scrotal rejuvenation). There is an increased awareness, reflected by the number of published medical papers, of vaginal rejuvenation; however, rejuvenation of the scrotum has not received similar attention in the medical literature. Scrotal rejuvenation includes treatment of hair-associated scrotal changes (alopecia and hypertrichosis), morphology-associated scrotal changes (wrinkling and laxity), and vascular-associated scrotal changes (angiokeratomas). Rejuvenation of the scrotum potentially may utilize medical therapy, such as topical minoxidil and oral finasteride, for scrotal alopecia and conservative modalities, such as depilatories and electrolysis, for scrotal hypertrichosis. Lasers and energy-based devices may be efficacious for scrotal hypertrichosis and scrotal angiokeratomas. Surgical intervention is the mainstay of therapy for scrotal laxity; however, absorbable suspension sutures are postulated as a potential intervention to provide an adequate scrotal lift. Hair transplantation for scrotal alopecia and injection of botulinum toxin into the dartos muscle for scrotal wrinkling are hypothesized as possible treatments for these conditions. The interest in scrotal rejuvenation is likely to increase as men and their physicians become aware of both the conditions of the scrotum that may warrant rejuvenation and the potential treatments of the scrotum for these individuals.

Abstract
BACKGROUND AND AIMS Laser hair removal has recently become a major indication. Diode lasers have become commercially available offering two modes of application: a stamping or static mode, and a dynamic mode whereby the handpiece is continuously moved across the target tissue. The present study was designed to compare the efficacy of these two approaches clinically and histologically. SUBJECTS AND METHODS Twenty-five subjects participated in the study, 12 males and 13 females, ages ranging from 20 to 57 yr (Mean age 41.6 yr). A baseline hair count was performed on both the target areas. The ms-pulsed diode laser delivered 810 nm via a handpiece with a cooled tip, offering both static and dynamic modes which were used on the subjects' left and right crura, respectively. Pain during treatment was assessed using a visual analog scale (VAS) and gross inspection was performed immediately after treatment for any abnormality in the treated skin. Hair counts were performed on both crura at 1 and 3 months after the treatment, and compared with the baseline counts. Biopsies were performed in the dynamic mode treated skin at baseline and at 1 month after the treatment, and assessed with light microscopy, immunohistochemistry and transmission electron microscopy (TEM). RESULTS All subjects completed the study. Compared with baseline, hair counts were significantly lower at 1 and 3 months post-treatment with no significant difference between the static and dynamic laser depilation modes, nor in the severity of the pain experienced during the procedure. Histologically, degenerative changes in the hair follicles were noted immediately after laser treatment. At one month, cystic formation was seen in the hair follicles showing a strong tendency towards apoptotic cell death. CONCLUSIONS With the diode laser system and at the parameters used in the present study, high depilation efficacy was seen with no significant difference between the static and dynamic modes. Interestingly, good long-term depilation is probably a result of induced apoptotic cell death in the follicles rather than any other mechanism.

Abstract
Ocular tissues are known to be sensitive to damage from exposure to laser emissions. This study reports the case of a female patient with acute unilateral anterior uveitis caused by alexandrite laser-assisted hair removal of the eyebrows. We report a 38-year-old female who presented with unilateral eye pain, redness, and photophobia after receiving alexandrite (755 nm) laser epilation of both eyebrows. Best corrected visual acuity was 20/20 in both eyes. Right eye examination was normal. Left eye examination showed conjunctival injection and 2+/3+ cells in the anterior chamber. Intraocular pressure and fundus examination were normal. Topical steroids and cycloplegic drops were prescribed for 3 weeks. At the end of the 3-week follow-up, best corrected visual acuity was 20/20, and intraocular pressure and fundus examination were normal in both eyes. The left eye was white, and the anterior chamber was clear. The patient continues to be monitored. In conclusion, without adequate protective eyewear, laser hair removal of the eyebrows with alexandrite laser can lead to ocular damage.

Abstract
Demand for non-invasive techniques to treat oculofacial pathology has allowed for the growth and development of several new laser and light therapy modalities. These modalities include the use of intense pulsed light (IPL) and photodynamic therapy (PDT), light-emitting diode devices, as well as ablative and non-ablative lasers. Therapeutic applications in the periorbital area may involve the treatment of vascular lesions, telangiectasias, dyspigmentation, photodamage, hypertrichosis, rhytids, and scars. Laser and light-based technology offers patients treatment options that range from conservative to aggressive, allowing for choices between subtle results with little downtime or dramatic results with longer downtime. Advantages of laser treatments, as compared to traditional medical and surgical treatments, include a longer lasting effect than some of the conservative therapies and the ability to serve as a happy medium between non-invasive topical medicine and invasive surgical techniques. For patients seeking non-invasive alternatives, these modalities confer a major advantage over incisional surgery. Understanding appropriate usage, side effects, and outcomes is before treating functional and cosmetic issues. Here we present a review of current treatment modalities, their use, side effects, and outcomes.
