Accepted for publication August 10, 2021. Synopsis As a milder form of clinical acne, physiological acne is very common in adults. The safety and effectiveness of the present anti-acne agents put an increasing demand on the development of the desired anti-acne cosmetic products. This study was conducted to clinically investigate the effectiveness of a topical anti-acne skincare cosmetic treatment for adult acne-prone skin. In the study, the volunteers’ acne condition on their skin surface, the moisture content, the transepidermal water loss, the proportion of pore area, and the skin surface lipids were all tested. Objective and clinical evaluation methods were used to evaluate the ability to improve the clinical signs of physiological acne present in adult subjects, and self-evaluation questionnaires conducted by the subjects themselves were also used. Thirty healthy volunteers with acne lesions were recruited for the study and treated with an “anti-acne cream” for 4 weeks. The product was applied on thoroughly cleansed skin twice a day. The results were evaluated after 14 and 28 d. Within 4 weeks of the test period, the product effectively improved the moisture content of the cuticle, repaired the skin barrier function, and then enhanced the ability of the skin to resist external stimulation. It also regulated the skin oil secretion, reduced the proportion of pore and porphyrin areas, and reduced the a value. The clinical evaluation showed that the number of acne lesions (including open acne, closed acne, papules, and pustules) decreased, and the pores, greasiness, and moisture all improved. The current study suggests that the product is suitable for the cosmetic care of adult acne-prone skin. INTRODUCTION Acne vulgaris is a common dermatological disorder with about 85% of the world’s population suffering to some degree (1–3). Young people are not the only age group prone to acne, as other groups including children and the middle-aged are also affected (4,5). Acne is a disease of the pilosebaceous unit and results from three possible main pathogenetic factors: seborrhea, abnormal keratinocyte proliferation, or follicular colonization with Propionibacterium acnes (P acnes) (4,6). It is well known that some significant psychosocial morbidities are caused by acne (7). Studies show that acne affects the general quality of life of patients, including their self-esteem, self-image, and emotions (8–10). Lasek and Chren (11) determined that the most troubling factor for acne vulgaris patients was the appearance of the skin. Antibiotics are one of the great discoveries of the modern era. However, the abuse of antibiotics can cause immune responses, such as fever and skin rashes. Benzoyl J. Cosmet. Sci., 72, 568–579 (November/December 2021)
