BHA

Butylated Hydroxyanisole

Butylated Hydroxyanisole (BHA) is a synthetic antioxidant used to protect cosmetic products from oxidation and spoilage. It helps prevent oils, fats, fragrances, and other ingredients from degrading when exposed to air, heat, or light, extending the shelf life and stability of a formulation.

🛡️
Safety: Generally considered safe for use in cosmetics at the low concentrations typically used. Some individuals with sensitive skin may experience irritation. BHA is used as a preservative-supporting antioxidant rather than as an active skincare ingredient.
