PotassiuM Azeloycinate Diglycinate is a whitening and acne-removing raw material. However, its application is greatly limited due to its water insolubility, high melting point, large dosage, easy discoloration, and poor compatibility. PotassiuM Azeloycinate Diglycinate is a newly developed azelaic acid derivative. It is soluble in water and used in small amounts. It has good effects on regulating oil secretion and has a stronger whitening effect.
