Azelaic Acid

Why Choose Azelaic Acid?

Azelaic Acid offers multiple skin benefits, including reducing acne-causing bacteria, minimizing post-acne marks, and targeting uneven skin tone and redness. It’s less irritating than many acids and safe for prolonged use on sensitive or rosacea-prone skin. In cosmetic use (up to 10%), it helps refine pores, fade discoloration, and calm inflammation.
