Azelaic acid is used to treat acne and rosacea. A naturally occurring dicarboxylic acid. It is non-toxic, non-teratogenic, and non-mutagenic. It is cytotoxic to melanocytes of human melanoma. In addition, azelaic acid can inhibit bacteria and regulate normal sebum secretion, The level of androgen testosterone in the body is too high, and it passes 5 years in the sebaceous gland- α The function of reductase is transformed into dihydrotestosterone, which leads to the hyperfunction of sebaceous gland, resulting in excessive oil secretion.

Azelaic acid compatibility is greatly limited due to its two natural defects of poor water solubility and high melting point.

40% Water-soluble azelaic acid can promote the absorption of the product to the skin by adding azelaic acid to cream cosmetics.

Azelaic acid can competitively inhibit 5- α The function of reductase inhibits the conversion of excessive androgen into dihydrotestosterone, and finally inhibits the excessive secretion of free fatty acids in sebaceous glands.

40% Water-soluble Azelaic acid can inhibit the production of reactive oxygen free radicals and play an anti-inflammatory role. The hydroxylation of aromatic compounds induced by reactive oxygen groups and the peroxidation of arachidonic acid were inhibited in vitro.
