Azelaic Acid 15% (TYR inhibitor)

A naturally occurring dicarboxylic acid found in grains like wheat, rye, and barley, also produced synthetically for pharmaceutical-grade use.

• Tyrosinase inhibition

  Interferes with the enzyme tyrosinase, which is required to convert tyrosine into melanin. This directly reduces new pigment production.

• Antibacterial and anti-inflammatory action

  Azelaic acid is also effective against Cutibacterium acnes (the bacteria implicated in acne) and normalizes keratinization, which is why it appears on both pigmentation and acne claims in the same product.

15% is a clinically meaningful concentration. Prescription azelaic acid formulations typically sit at 15–20%, so this isn't a diluted, cosmetic-grade dose.
