Background/purpose: The efficacy of cosmetics on human skin measured under normal mild laboratory environment might be discounted by exterior environment factors such as wind, UV exposure, etc. Few studies have focused on the 'genuine' efficacy of cosmetics on human skin during exposure to external rigorous environment. The aim of this study was to develop a model for the evaluation of the efficacy of cosmetics on human skin under simulated rigorous environment.
Methods: We measured skin water content and transepidermal water loss (TEWL) before and after products application under simulated windy and sub-erythema UV exposure treatment in a constant temperature and humidity laboratory.
Results: The results showed that the products had higher water content and lower TEWL at 2, 4 and 8 h of products application, and ameliorated the skin moisturization situation after a 3-week continuous use of the products. In addition, the products might protect the skin to maintain the normal water content and TEWL under the simulated windy or sub-erythema UV exposure treatment in our laboratory when compared with untreated area.
Conclusion: Our data indicate that this model may provide a more accurate evaluation for the genuine moisturizing effect of cosmetics under external natural climate.

Skin tags, medically known as acrochordons, are harmless growths of the epidermis that commonly develop in areas where the skin folds, such as the neck, armpits, or groin. While usually asymptomatic, these lesions can cause discomfort from rubbing or cosmetic issues. They are more prevalent in middle-aged and older individuals and are often correlated with conditions such as obesity, diabetes, and insulin resistance.

Background: This study aimed to investigate the effects of ginseng non-edible callus-derived extracellular vesicle (GNEV) on skin regeneration, particularly focusing on its impact on proliferation and migration in human dermal fibroblast (HDF).
Methods: GNEV was isolated from ginseng non-edible callus using sequential filtration and size exclusion chromatography (SEC). The extracellular vesicle was characterized using nanoparticle tracking analysis (NTA).

Aim: To present three cases of filler-induced alopecia (FIA) and summarize the current knowledge of its clinical features, mechanisms and treatments.
Methods: In the first two cases, two females developed well-defined triangular patches of hair loss after hyaluronic acid (HA) injections, and received corticosteriod injections with topical 5% minoxidil. The third case described another female who experienced alopecia areata-like hair loss after autologous fat grafting, and received combined therapies including corticosteriod, 5% minoxidil and microneedling.

Background: The increasing societal emphasis on physical appearance, particularly influenced by social media, has led to a significant rise in demand for aesthetic dentistry procedures. This study aims to explore the ethical dimensions of marketing practices and the phenomenon of overtreatment in cosmetic dental procedures, highlighting the implications for patient care and professional integrity.
Methods: A systematic literature review was conducted across four databases, yielding an initial 76 articles.
