Vitamin C is a beloved ingredient in K-beauty for its brightening and antioxidant properties. It helps even out skin tone, fade dark spots, and protect against environmental stressors like pollution and UV damage. K-beauty formulations often pair Vitamin C with hydrating and calming ingredients such as niacinamide and green tea extract to enhance its effectiveness while minimising irritation. Regular use can leave the skin looking radiant, refreshed, and more youthful.
