What it is
Water-soluble potassium salt formed by amidation of azelaic acid with two glycine molecules; water-soluble and pH-neutral at cosmetic concentrations, enabling formulation at lower acidity than raw azelaic acid; shares the tyrosinase-inhibiting and anti-inflammatory mechanism of the parent azelaic acid via mitochondrial electron transport and 5-alpha-reductase inhibition; better tolerated on sensitive skin where azelaic acid at 15–20% may cause stinging.
