Benefits of azelaic acid for hyperpigmentation and acne scars

Azelaic acid is a naturally occurring acid that has been found to be effective in treating both hyperpigmentation and acne scars. Several clinical studies have shown that topical application of azelaic acid can significantly reduce the appearance of hyperpigmentation and acne scars.

One study published in the Journal of Cosmetic Dermatology found that a 20% azelaic acid cream applied twice daily for six months improved hyperpigmentation in participants with melasma by up to 70%.

Another study published in the Journal of the European Academy of Dermatology and Venereology found that a 15% azelaic acid gel applied twice daily for six months significantly improved the appearance of acne scars in participants.

Overall, these studies suggest that azelaic acid can be an effective treatment for hyperpigmentation and acne scars, making it a valuable ingredient to look for in skincare products targeting these issues.
