Cosmetic Grade Azelaic Acid-CAS 123-99-9
Cosmetic Grade Azelaic Acid is a natural straight-chain dicarboxylic acid, a gold-standard mild skin-clearing active ingredient for acne and red mark repair in the skincare industry.
Different from high-irritation exfoliating and anti-acne ingredients, 99% high-purity azelaic acid achieves efficient skin conditioning with low skin burden, solving the common pain points of acne skin such as repeated acne, inflammatory redness, post-acne dark marks, oily dullness and rough pores.
It can precisely inhibit the activity of Propionibacterium acnes, cut off the bacterial growth environment, effectively improve inflammatory acne, closed comedones and pustules, and reduce acne recurrence. By regulating sebaceous gland secretion, it controls excessive oil production, balances skin water and oil, and refreshes oily and sticky skin.
In terms of skin repair and brightening, azelaic acid can inhibit the abnormal proliferation and activity of melanocytes, reduce local pigment deposition caused by inflammation, fade fresh red marks and old dark acne marks, and uniformly brighten skin tone.
With mild exfoliating power, it can accelerate the metabolism of aged keratin, unclog blocked pores, improve rough and dull skin texture, and refine enlarged pores. It has no photosensitive risk, safe for daytime long-term use, low irritation, and compatible with sensitive acne-prone skin. It is an indispensable core raw material for building safe, mild and efficient acne repair and skin conditioning skincare systems.
