Comoace Pure Sericin Silk Soap 100g
This soap is the ultimate first step in a silk-based skincare ritual. Unlike ordinary cleansers, it creates a dense foam that protects the skin barrier during washing. Enriched with Pure Sericin—a silk-derived protein similar to human skin—it hydrates, brightens, and shields your skin with every use. Ideal for those with dry or sensitive skin, this soap transforms cleansing into a nourishing step that primes your skin for enhanced absorption of serums and creams.
Key Benefits:
- Builds a rich foam that cushions and cleanses without stripping moisture.
- Sericin protects and locks in hydration better than hyaluronic acid.
- Reduces skin friction, ideal for delicate or sensitive skin.
- Boosts absorption of skincare applied after cleansing.
- Evens tone and brightens for a visibly smoother complexion.
Key Ingredients:
- Pure Sericin: Forms a moisture-locking film, smooths texture, and brightens tone
- Sodium PCA: Natural plant-based humectant that attracts and retains moisture
- Maltitol: A starch-derived sugar alcohol that hydrates while cleansin
- Sodium Hyaluronate: A deeply penetrating form of hyaluronic acid that boosts elasticity and moisture retention.
How to Use:
- Using a foaming mesh, whip the soap into a dense foam about the size of a lemon.
