Vitamin C is a highly regarded ingredient in K-Beauty for its brightening and antioxidant properties, helping to promote a radiant, even-toned complexion. It works by reducing the appearance of dark spots and post-acne marks while protecting the skin from environmental stressors that can contribute to premature ageing. Commonly found in serums and ampoules, Vitamin C is often paired with hydrating and soothing ingredients to maximise its benefits while minimising irritation, making it an essential step in achieving the luminous, healthy-looking skin that K-Beauty is renowned for.
