Antioxidant
An antioxidant is a key ingredient in skincare and cosmetic products that helps protect the skin from damage and aging. Think of it like a shield that guards both the product and the skin against harmful elements in the environment. In cosmetics jobs, this term comes up when people work on creating or improving beauty products. The most common antioxidants include Vitamin C, Vitamin E, and plant extracts. When you see this on a resume, it usually means the person has experience working with these protective ingredients in product development, formulation, or quality control.
