Gain of Protection Afforded by the Methoxypropylamino Cyclohexenylidene Ethoxyethylcyanoacetate (MCE) UVA1 Filter on Pigmentary and Aging Signs: An Outdoor 4-Week Randomized, Intra-Individual Comparative Study in 52 Brazilian Women.

Background: Conventional sunscreens shield the skin from ultraviolet (UV) rays up to 370 nm leaving wavelengths between 370 and 400 nm unfiltered despite their potentially harmful biological and clinical effects.

Objective: The beneficial effects of methoxypropylamino cyclohexenylidene ethoxyethylcyanoacetate (MCE) UVA1 filter were explored at 1% in a SPF50 sunscreen under outdoors summer conditions against pigmentation and aging signs compared against a reference SPF50 without the MCE filter.

Materials And Methods: A prospective randomized comparative intra-individual study was conducted in 52 Brazilian women (phototype I-III).

A Psychosocial Exploration of Augmented Reality and Virtual Reality Apps in Cosmetic Procedures.

Background: The integration of augmented reality (AR) and virtual reality (VR) technologies into cosmetic dermatology offers new avenues for enhancing patient engagement, satisfaction, and decision-making. These immersive tools allow patients to better visualize the outcomes of procedures before treatment, improving communication with physicians and increasing confidence in cosmetic interventions. Despite the promise these technologies hold, there remain concerns regarding their accessibility, technical limitations, ethical challenges, and the potential for algorithmic bias.

Grading facial aging: Comparing the clinical assessments made by three dermatologists with those obtained by an AI-based scoring system that analyses selfie pictures. A focus on Chinese subjects of both genders.

Objective: The objective of this study is to assess the correspondence, in live conditions, between clinical gradings of facial aging signs by three dermatologists and those afforded by an automatic AI-based algorithm that analyses smartphones' selfie images of Chinese subjects.

Methods: In total, 125 Chinese subjects of both genders, aged 18-62y, took a selfie using their own smartphones and were immediately viewed by three dermatologists. The latter graded the severity of 15 facial signs in women and 9 in men, using the standardized values afforded by a Skin Aging Atlas referential dedicated to Asian skin.
