This study aimed to assess the psychosocial effects of acne scars on patients with skin Phototypes IV-VI. This retrospective multicenter observational study involved 86 patients with acne scars who had previously consulted general practitioners. Scar severity was assessed using the Echelle d'évaluation Clinique des Cicatrices d'Acné (ECCA). Validated measures were used to evaluate psychological and quality-of-life impacts: the Patient Health Questionnaire-9 (PHQ-9) for depressive symptoms and the Dermatology Life Quality Index (DLQI) for quality of life. The study revealed that 62% of patients exhibited depressive symptoms according to the PHQ-9, and 84% reported a diminished quality of life according to the DLQI. A significant correlation was observed between acne scar severity and both psychosocial measures: ECCA and DLQI (<i>r</i> = 0.31, <i>p</i>=0.003), and ECCA and PHQ-9 (<i>r</i> = 0.27, <i>p</i>=0.010). Many participants had modified their clothing and daily activities due to their scars. The findings illustrate the profound psychosocial burden of acne scars, with a notable percentage of individuals experiencing depressive symptoms and reduced quality of life. The strong correlation between scar severity and psychosocial outcomes emphasizes the need for early, comprehensive care that addresses both dermatological and psychological aspects.</p>","PeriodicalId":11338,"journal":{"name":"Dermatology Research and Practice","volume":"2025 ","pages":"6657441"},"PeriodicalIF":1.9,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12496151/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145231697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 12-question survey was administered to 100 patients presenting for treatment of a skin cancer at an academic center. The first six questions addressed the importance the patient placed on treatment cost and related discussions, and the final six questions addressed repair cost.

Most patients reported that the cost of skin cancer treatment (56%) and repair (54%) should be considered by their surgeon.

A decrease in hair lipid content correlates with reduced tensile strength, diminished shine, increased breakage, and hair damage. In this study, we focus on Lipid Bond Technology with small molecule real lipids derived from plant oil triglycerides, known as 369LAB Lipid Bond, reverse chemical and environmental damage by restoring lipid bonds in hair, regenerates hair structure, and improves hair strength. Research results show that 369LAB Lipid Bond has an average particle size of 39.83 nm, helping to penetrate deeply into the hair; replace lost lipids, restore lipids to damaged hair. After one use, the total amount of lipid restored is equivalent to natural hair before damage. It is nonsticky and does not clog hair follicles. SEM images show morphological improvement in the integrity of the epidermis and regeneration of lipid layers immediately, with lasting repair even after discontinuation of use. The amount of force that breaks individual hair strands in testing shows that 369LAB Lipid Bond makes hair stronger.
