Composition containing sinapinic acid or its salts as an active ingredient for improving skin wrinkles, hydration, elasticity, exfoliation, erythema reduction, or photoaging.

Inner Beauty Ingredient Using Sinapinic Acid for Moisturizing, Exfoliation, and Erythema Reduction

This technology utilizes sinapinic acid or its salts as an active ingredient in cosmetic and functional food compositions to enhance skin hydration, promote exfoliation, and reduce erythema. It can be used for photoaging management through both topical application and oral intake.

Repeated UV exposure increases reactive oxygen species and inflammatory signals, activating collagen-degrading enzymes like MMPs, which leads to loss of elasticity, wrinkles, and photoaging. Furthermore, topical cosmetics have limitations in delivering active ingredients to the dermis, driving the demand for ingestible inner beauty solutions.

This technology leverages the ability of sinapinic acid to increase skin moisture content, reduce transepidermal water loss, normalize thickened epidermal layers, and protect the collagen fiber network at the dermal-epidermal junction. With proven procollagen stimulation and MMP inhibition, it is a highly valuable ingredient for photoaging care. It can be applied to moisturizing creams, soothing ampoules, and functional skin health foods, allowing for a comprehensive photoaging care lineup based on a single ingredient.
