Function of Azelaic Acid
Azelaic acid is extracted from wheat, rye, and barley, and is widely used in cosmetics and medicine.
Azelaic acid can block the process of melanin synthesis, which is related to the formation of skin spots, which can lighten brown spots or other skin spots. Therefore, it is a good choice for freckle and acne. In addition, as a raw material for anti-freckle and anti-acne, azelaic acid is included in the authoritative dermatological pharmacopoeia, so it also has high safety.
Azelaic acid is also an antioxidant and exhibits significant anti-inflammatory properties. When used externally, it can effectively improve skin inflammation and help reduce red acne marks and redness caused by rosacea. Azelaic acid is not very effective for ordinary skin whitening, but it has a very obvious effect on severe pigmentation, such as freckles, melasma, melanoma, etc.
