Vitamin C: A Potent Ally Against Skin Aging

Skin aging is a natural process influenced by genetics and environmental factors, such as UV exposure and pollution. However, recent research highlights that vitamin C, a common daily supplement, can significantly slow down skin aging.

According to a recent study reported by UNILAD, daily vitamin C supplementation improves skin elasticity, reduces wrinkles, and supports collagen synthesis. Vitamin C’s antioxidant properties combat free radicals that damage skin cells, which contributes to a youthful complexion and healthier skin resilience.
