Science & Benefits

Butylene Glycol is a small organic alcohol used as a humectant and solvent. It has a significantly lower potential for skin irritation than propylene glycol. While it carries a minimal comedogenic rating of 1, it is considered safe for almost all acne-prone skin types. It functions by decreasing the viscosity of a formula, ensuring that active ingredients spread evenly across the skin surface and penetrate the pore lining effectively.
