POLYGLYCERIN-3

Polyglycerin-3 is polymerized glycerin, which is used in cosmetic products to moisturize the skin. Due to its large molecular size, it penetrates the skin comparatively slowly and thus ensures long-lasting moisturization. It also forms a protective barrier, binds water and traps it in the upper layers of the skin. It is recommended for use in cosmetic products and was classified as safe in a safety assessment for cosmetic ingredients. (1)
