Science & Benefits

Hydroxypropyl Starch Phosphate is a plant-based, modified starch that functions as a high-performance rheology modifier. In acne-safe gels, it creates a unique, 'velvety' texture that eliminates the stickiness often associated with high-glycerin products. As a humectant, it forms a breathable, non-occlusive moisture film that keeps the skin hydrated throughout the day. It is completely non-comedogenic and zero-irritant. It is a strategic 'aesthetic' ingredient that allows for the creation of rich, luxurious product textures that remain 100% oil-free and safe for congested skin.
