Azelaic acid powder is also known as azalea acid. Although it is called azalea acid, it has nothing to do with azalea. It is a natural saturated dicarboxylic acid with an appearance of white to yellowish monoclinic prisms, needle crystals or powder.
As an acid, azelaic acid powder has no photosensitivity and can be used during the day. It is less irritating and gentler than common organic acids such as salicylic acid and fruit acid.
Remove acne and improve acne
By reducing the synthesis of filamentous keratin, azelaic acid reduces hair follicle hyperkeratosis, inhibits epidermal keratinization, and has the effect of unblocking pores. It can prevent the formation of acne, fade acne marks, and inhibit post-inflammatory pigmentation. Azelaic acid is a very good acne treatment. However, it is generally only used to treat mild to moderate acne, and is clinically used in conjunction with A acid to treat more severe, moderate to severe acne.
Whitening
Azelaic acid powder inhibits DNA synthesis and mitochondrial enzyme activity in overactive melanocytes (it has no effect on normal melanocytes). Competitive inhibition inhibits tyrosinase activity.
Oil control
5a-reductase is a key enzyme in skin androgen metabolism, and androgens can stimulate sebaceous glands to secrete oil. Azelaic acid powder can effectively inhibit 5a-reductase, thereby improving oil secretion.
