Abstract

Skin, hair, and nails are essential indicators of overall health, functioning not only for aesthetic appeal but also as the body’s primary defense against environmental factors. Despite the abundance of skincare, haircare, and nail care products available on the market, many fail to address fundamental issues like collagen depletion, oxidative stress, and structural damage. This study investigates the effects of promarine collagen tripeptides (PCT) on improving skin, hair, and nail health. Sixty subjects were recruited and randomly assigned to either a placebo group or a PCT group. Subjects consumed one bottle of either the placebo or PCT daily for 12 weeks. Assessments of skin, hair, and nail conditions were conducted at baseline (week 0), mid-study (week 6), and post-study (week 12). Self-assessment questionnaires were also collected at weeks 0 and 12 to evaluate perceived improvements. Compared to the placebo group, the PCT group showed significant improvements in skin elasticity, wrinkle reduction, hair strength, and nail health. Self-assessment results from participants also indicated notable perceived improvements. PCT effectively enhance skin, hair, and nail health through various biological pathways, providing a safe and effective supplement to improve overall appearance and well-being.
