Science

On the skin, Glycereth-20 acts as a potent humectant, drawing environmental moisture to hydrate the skin and reduce transepidermal water loss. It also functions as an emollient and lubricant, enhancing skin softness, elasticity, and providing a smooth feel. Within a formulation, it stabilizes oil and water phases as an emulsifier, and notably, it can bolster the penetration and overall efficacy of other active ingredients.
