Medicube Azelaic Acid 16 Calming Serum is a potent, fast-absorbing treatment designed to target acne, redness, dark spots, and uneven skin texture with a high concentration of 16 % azelaic acid. This powerful serum helps regulate sebum production, soothe inflammation, and visibly improve post-acne marks while niacinamide works to even out skin tone and strengthen the skin barrier. Hydrating and calming ingredients like panthenol and centella extract support moisture retention and reduce irritation, leaving skin clearer, smoother, and more balanced with regular use.
