What This Ingredient Does

Vitamin C is a water-soluble antioxidant that plays a crucial role in collagen synthesis, immune function, and protection against oxidative stress. It is required for the production of collagen, the structural protein responsible for skin strength, elasticity, and wound healing.

Adequate vitamin C levels help support normal skin repair processes and protect skin cells from free radical damage caused by environmental stressors such as pollution and UV exposure. This antioxidant activity helps protect skin structure and reduce oxidative damage over time.

Vitamin C is often combined with other antioxidants and skin-support nutrients in supplements to support long-term skin health and systemic antioxidant protection.
