Sericic acid is primarily used in cosmetic and skincare formulations due to its moisturizing and skin-conditioning properties. It helps improve skin hydration by supporting the natural barrier function, making it beneficial in products designed for dry or sensitive skin. Its origin from natural sources, particularly silk-derived proteins, makes it suitable for use in natural and eco-friendly beauty products. Sericic acid is commonly found in creams, lotions, serums, and facial masks where it contributes to a smooth, soft skin feel. Additionally, it may enhance the stability of emulsions and improve the spreadability of topical formulations. Its compatibility with other active ingredients allows for broad use in anti-aging and restorative skincare lines.
