Azelaic Acid

Description: Naturally occurring dicarboxylic acid produced by a yeast that lives on the skin (also found in wheat, rye, and barley). Used to treat mild-to-moderate acne and rosacea by reducing inflammation and bacterial growth in hair follicles/pores.
Cosmetic Benefits (as listed)
• Gently exfoliates (removes dead skin cells that cause dull tone and clogged pores)
• Fights acne (antibacterial/bactericidal against P. acnes; reduces current and future blemishes)
• Reduces inflammation (soothes irritation and improves red bumps)
• Evens skin tone (inhibits tyrosinase → reduces post-inflammatory hyperpigmentation and can help with melasma; limited effect on normal pigment, freckles, age spots, or nevi)
• Treats rosacea (helps with pore-clogging, inflammation, and secondary infections; less irritating option for sensitive skin)
• Generally considered safe for pregnant women (one of the few options for acne/rosacea/clogged pores/pigmentation)
• Gluten-free (despite wheat origin; unlikely to be absorbed enough through skin to trigger sensitivity)
• Possible benefit for alopecia/hair loss (some reports; occasionally compounded into hair products)
