Azelaic AcidBenefits, how to use & safety
Acne, redness and dark marks, handled in one step.
What is Azelaic Acid?
Azelaic acid is a naturally occurring dicarboxylic acid found in grains such as barley and wheat. It is one of the few actives with strong evidence for acne, rosacea and pigmentation at the same time, and it is generally kind to sensitive skin.
How it works
It reduces the growth of acne-related bacteria, normalises how skin cells shed inside pores and dampens inflammatory signals that cause redness. It also slows tyrosinase in overactive pigment cells, so it fades marks without bleaching normal skin.

How to use it
Use a 10% over-the-counter formula once or twice daily after cleansing and before moisturiser. Higher strengths of 15–20% are usually prescription-led. Expect mild tingling for the first week or two. Results build over 8–12 weeks.
