Abstract
Background: The optimal timing of laser epilation with expanded forehead flaps in facial defect reconstruction remains undetermined. Objective: To compare the efficacy and safety of hair removal during or after flap expansion. Methods: This prospective exploratory study included 15 (11 women and 4 men, 16.47 ± 16.331 years of age) and 26 (19 women and 7 men, 10.69 ± 10.899 years of age) patients who underwent 755 nm long-pulsed alexandrite laser epilation during flap expansion and after surgery, respectively. Facial reconstruction was performed in these patients because of congenital melanin nevus, scar or port-wine stains. Evaluation included hair reduction rate, patient satisfaction, and adverse events. Results: The median number of laser sessions for hair removal during flap expansion was significantly lower than that after surgery (2.00 vs. 3.00, p < 0.01), and the hair reduction rate was also significantly higher during flap expansion (79.5% ± 21.93% vs. 68.3% ± 17.44%, p < 0.05). No severe adverse events were reported. Conclusion: Laser hair removal is safe and efficient when performed both during flap expansion period and after surgery, but its efficacy was significantly higher, and fewer sessions were required when performed during tissue expansion. Clinical trial registration information: ChiCTR1900026090.

Abstract
Background: Alexandrite 755 nm laser has been currently recognized one of the gold standards for the permanent hair removal business because of its sufficient tissue penetration and higher affinity for melanin compared with Nd:YAG, making the treatment more incisive and effective. Objective: In this study, we evaluated an Alexandrite 755 nm laser with a 30-mm spot for a new and fast hair removal treatment. Methods: Patients of both genders, with skin Fitzpatrick's types, ranging from II to III, were asked to avoid any epilation techniques 4 weeks before the laser hair removal session. Participants underwent a minimum of three to a maximum of eight sessions of treatment, every 6 weeks. Six months after the last treatment, the final evaluation was completed. The treated body areas included arms, legs, axillae, and trunk. The subjects used a numeric scale with a range of 0 to 10 (0: no pain, 10: unbearable), to indicate the associated pain level experienced. By comparing the percentage of terminal hairs before and after laser treatment, hair reduction was determined. Results: The patients reported only slight post-treatment erythema that disappeared after a few hours and only two patients showed persistent erythema lasting a few weeks. The pain was found to be 4.9 ± 0.9 after single pass emission. Conclusions: The 755 nm laser with the new handpiece has proven to be an ideal wavelength for hair removal, allowing efficient, safe, and faster treatments to be performed for the patient.

Abstract
The lack of uniform and objective techniques to evaluate treatment efficacy in photo-epilation studies leads to contradictory results. Thus, there is an urgent need to explore commonly accepted assessment tools. One of the most common methods uses hair counts via digital photography. However, macrophotography may not be able to depict the vellus-like hair induced by photo-epilation. On the other hand, handheld dermatoscopy is practical, affordable and offers high-quality magnification. Hair counts from a handheld dermatoscope and a digital camera were compared in 73 women who underwent 6 sessions with the Alexandrite 755 nm laser. Significantly more hairs were counted using the dermatoscope than using the digital camera (76.9 ± 41.3 vs. 58.6 ± 31.4, p < .005), independently of hair thickness and hair density. The difference in hair counts between the two instruments was inversely related to hair thickness and directly related to hair density. The handheld dermatoscope may be a more effective tool than the widely used digital camera in evaluating the response to laser hair removal treatment.

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 reduction is a common practice that utilized light-based therapy to prevent future hair growth. Complications following laser hair reduction treatment include thermal burns, which may lead to hyper- or hypopigmentation, hair stimulation, scar, or transient erythema of treated areas. AIMS Review reports of persistent urticaria following laser hair reduction and discuss a rarely discussed laser complication. METHODS Pubmed literature review. RESULTS There have been very rare reports of persistent urticaria following laser hair reduction. Similar case reports have also been described though no definitive reasoning for this reaction, nor consistent treatment has been documented. DISCUSSION In this report, we present a patient who developed persistent urticaria with severe pruritus in the areas treated with laser hair reduction. Previous reports an association was found between allergies and post-treatment urticarial eruption, with 33/36 patients having allergies, mostly to dust mites which is similar to the patient presented. Other etiologies such as reaction to cryogen and physical urticaria are unlikely. CONCLUSION Our report highlights a case of persistent urticaria with severe pruritus following laser hair reduction treatment, with both similarities and differences to other cases reported in the literature. While this is a rare side effect of laser hair removal, it should be monitored in patients who have a history of moderate to severe environmental allergies.

Abstract
Background and Objectives: Hair removal is a common cosmetic problem interesting more and more patients nowadays. Various laser treatments are currently available. Alexandrite and Nd:YAG laser are the most effective procedures in lighter and darker skin phototypes, respectively. Materials and Methods: A total of 40 patients seeking hair removal in one or more body areas with skin phototypes 2-6 was recruited to perform this study. Patients were divided into two groups. One group was treated with the standard Nd:YAG hair removal procedure, while the other group was treated with a new "in motion" Nd:YAG technology. Results and hair removal rates were evaluated six months after the last treatment. Results: Out of 40 patients treated, all patients experienced hair reduction. No statistically significant difference in hair removal was noted between the two groups; however, a statistically significant reduction in pain during the procedure was observed in the group treated with the "in motion" technique. Conclusions: While traditional and "in motion" Nd:YAG techniques have similar result outcomes in hair removal, the "in motion" technology seems to guarantee a better safety profile compared with the traditional technique. A more extensive clinical study will be necessary to confirm our study's results.

Abstract
Recent years have brought forth the undeniable practice gap in dermatology concerning knowledge and experience of cosmetic procedures in people of color (POC). A paucity in the literature regarding evidence-based recommendations for the management of POC undergoing cosmetic procedures and the rise of cosmetic procedures in dermatology serves as a call to action to provide education regarding differences in skin of color that may impact the cosmetic outcomes. To mitigate the current practice gap on the safety, use, and benefits of cosmetic procedures in POC, part 2 will discuss the authors' recommendations and clinical pearls, as well as evidence-based management for neuromodulators, soft tissue augmentation, chemexfoliating agents, and laser hair reduction in POC undergoing cosmetic procedures.

Abstract
BACKGROUND Paradoxical hypertrichosis (PH) is an uncommon, poorly understood adverse effect associated with laser or intense pulsed light treatment for hair removal. OBJECTIVE The objective of this study was to conduct a systematic review and meta-analysis to determine PH prevalence and associated risk factors. METHODS We conducted a systematic review and meta-analysis of studies evaluating hair removal with lasers or intense pulsed light. Primary outcome was PH prevalence. Meta-regression and subgroup analysis were used to investigate associations among treatment modality, patients' characteristics, and PH. RESULTS Included were 9733 patients in two randomized controlled trials and 20 cohort studies (three prospective and 17 retrospective). Pooled PH prevalence was 3% (95% confidence interval 1-6; I2 = 97%). Paradoxical hypertrichosis was associated with a face or neck anatomic location, and occurred in only 0.08% of non-facial/neck cases. Treatment modality and interval between treatments had no effect on the PH rate. There were insufficient data to determine the association between sex and skin type to PH. In three out of four studies, PH gradually improved with continued therapy. CONCLUSIONS Based primarily on cohort studies, PH occurs in 3% of patients undergoing hair removal with lasers or intense pulsed light, yet rarely outside the facial/neck areas. Treatment modality does not seem to be a contributing factor. Continuation of treatment in areas with PH may be the most appropriate treatment.

Abstract
BACKGROUND Laser hair removal has become popular means of achieving hair reduction with improved quality of life. OBJECTIVE This study aimed to assess the safety and efficacy of Multipass low fluence, high-frequency 755-nm Alexandrite laser versus the high fluence, low-frequency 1064-nm long-pulsed Nd: YAG laser on axillary hair reduction in women with dark skin phototypes. PATIENTS AND METHODS This study was carried out on 30 adult women [skin type, IV-VI)] who seek axillary hair reduction. These subjects were adjusted to receive 5 laser sessions with a 1-month interval. One side received high fluence, low-frequency 1064-nm laser where the other side received multipass low fluence, high-frequency 755 nm laser. The follow up was done using photographs, folliscope, patients' visual analog pain scale. RESULTS The mean percentage of hair density reduction showed significant improvement in both treated sides being higher in the Alex treated side with corresponding significant decreases in the mean hair thickness. CONCLUSION Multipass low fluence, high-frequency 755-nm Alex laser practice was verified to be safe and effective for hair removal in dark skin phototypes compared to the high fluence, low frequency 1064-nm long pulsed Nd:YAG laser.
