Azelaic acid

Function: Anti-acne, Soothing, Buffering, Skin brightening, Antioxidant

Azelaic acid is a naturally occurring acid found in fungi and certain grains. It offers several benefits for the skin, including reducing inflammation, decreasing redness, killing acne-causing bacteria, fading dark spots, improving skin texture, protecting against free radicals, and reducing sensitivity over time. It can be easily incorporated into skincare routines and works well with other ingredients.

For acne, azelaic acid prevents the thickening of the top layer of dead skin cells, which can clog pores and lead to breakouts. It also has antibacterial and anti-inflammatory properties, making it effective for treating inflammatory acne.
