Title: The Impacts of Sun Protection and Skincare Habits in the Biophysical and Morphological Properties of Men’s Skin Authors: Infante V, et al. Published: Journal of Cosmetic Dermatology, April 2022 Keywords: Radiation, Sun Protection, Sunscreen Abstract: Studies have demonstrated that UVB radiation may cause changes in the epidermal permeability barrier and in the stratum corneum hydration. It is well known that sun exposure causes erythema, skin cancer and other physiologic alterations. The objective of this study was to evaluate the cosmetic use and sun protection habits of young men, correlating their lifestyle with the biophysical and morphological skin characteristics, as well as to study how skin unprotected can affect these features even in young people. 60 participants between 18 and 28 years old were divided into two groups: with photoprotection habits (PP habits) and without photoprotection habits (No PP habits). They were questioned about their sunscreen and cosmetic products use. The skin parameters were evaluated using biophysical and skin imaging techniques. 60% did not apply sunscreen often and 80% did not consume other skincare products. No PP habits group presented an increase in the transepidermal water loss – TEWL and sebum level, as well as a reduction in the stratum corneum water content and dermis echogenicity. The skin characteristics evaluated were correlated with the sun protection habits and skincare behaviour showing that men face some sociocultural barrier to start the use of cosmetic products.

Title: Presentation, Patterns and Surgical Management of the Complications of Thread Rhinoplasty Authors: Jin H, Kim S Published: Clinical and Experimental Otorhinolaryngology, April 2022 Keywords: Complications, Rhinoplasty, Threads Abstract: Non-surgical rhinoplasty using threads has gained popularity in recent years. While the benefits of this procedure are being emphasised, possible complications and their management are not well-known. This study aimed to present the surgical management and results of the complications of a thread rhinoplasty. We retrospectively reviewed the medical records of seven patients who underwent revision rhinoplasty due to the complications of thread rhinoplasty from January 2018 to May 2021. The presentation of complications, detailed surgical procedure, and the outcomes of revision rhinoplasty were reviewed. Visible or extruded threads at the tip were the most common complication, followed by dorsum irregularity. All the threads were not absorbed and intact in shape, even several years after insertion. Thread removal required careful tissue dissection, resulting in the loss of tip support and dorsal irregularity. To restore the tip support and camouflage the dorsum shape, an autologous tissue graft was required. Removal of threads at the tip and dorsum accompanied structural weakening and partial tissue loss, which required tip support restoration and dorsum camouflage. Title: Efficacy and Tolerability of a Microneedling Device for Treating Wrinkles on the Neck Authors: Alqam M, et al. Published: Aesthetic Surgery Journal, April 2022 Keywords: Microneedling, Neck Ageing, Wrinkles Abstract: A microneedling pen has been cleared by the US Food and Drug Administration and is indicated for improving the appearance of facial acne scars in adults. This study assessed the effectiveness of this pen for treating wrinkles. The paper focuses on the neck, an area of recent importance with video meetings placing stress on the neck area leading to wrinkles. Healthy adult men and women were enrolled. Subjects received four monthly microneedling procedures at depths up to 2.5 mm. Wrinkle assessments were performed by two trained blinded raters by comparing images of each subject at baseline and at 90 days post-procedure. The two raters were unblinded for the Clinician’s Global Aesthetic Improvement Scale (CGAIS) assessment. Subjects completed the Subject’s Global Aesthetic Improvement Scale (SGAIS) and a Satisfaction Questionnaire at 30- and 90-days post-treatment for the treatment areas of the face and neck. The study was completed by 32 subjects. Wrinkle assessments demonstrated significant improvement in the neck areas. The SGAIS and CGAIS showed significant improvements at 90 days posttreatment. Most subjects reported some level of improvement in their appearance at 30 days (73.3%) and 90 days (68.8%) post-treatment. The satisfaction questionnaire showed high levels of improvement in wrinkles (93.8%), satisfaction (87.5%), and would recommend microneedling to friends and family members (80.6%).

Title: Clinical Utility of Botulinum Toxin Type A Local Injection Therapy for Head and Forehead Hyperhidrosis Authors: Ando Y, et al. Published: Journal of Dermatology, April 2022 Keywords: Botulinum Toxin, Hyperhidrosis, Sweating Abstract: Head and forehead hyperhidrosis (HFH) is a disease that causes a large amount of sweating from the head region, and it significantly reduces patients’ quality of life. Only a few reports have shown the effectiveness of botulinum toxin type A (BTX-A) local injection therapy (BTX-A therapy) for HFH. To clarify the benefits of BTX-A for HFH, BTX-A therapy was performed in 15 patients, and its efficacy was evaluated. The amount of sweating was measured by the ventilation capsule method and Minor’s iodine-starch test. Evaluation was also performed using the Hyperhidrosis Disease Severity Scale (HDSS) and the Dermatology Life Quality Index (DLQI). In most cases, a remarkable antiperspirant effect was observed from 2 weeks after the injection, and the effect lasted for approximately 30 weeks. HDSS and DLQI improved along with the decrease in sweating. Two patients (13.3%) complained of transient mild ptosis. There were no serious side-effects. This study showed that BTX-A therapy is a safe and effective treatment for HFH.
