Science & Benefits

Glycereth-20 is a polyethylene glycol ether of glycerin. In modern formulations, it acts as a superior humectant and solubilizer that bridges the gap between water and oil. It provides a 'cushioned' hydrating feel that is significantly less sticky than pure glycerin. Because it is highly hydrophilic, it cannot lodge in the follicle or contribute to sebum oxidation (rating 0). It is a 'bulletproof' functional ingredient for ensuring that acne-safe serums remain clear and stable while delivering a surge of moisture to the epidermis.
