Azelaic acid is a naturally occurring compound that is commonly found in grains, such as barley, wheat, and rye. It is a common ingredient in skincare products due to its many benefits for the skin. Here are a few of its main uses in cosmetics:
1. Acne: Azelaic acid has antibacterial properties that help to prevent the growth of acne-causing bacteria. It also helps to regulate oil production and unclog pores, which can lead to fewer breakouts.
2. Hyperpigmentation: Azelaic acid has been shown to reduce the appearance of hyperpigmentation, such as age spots, melasma, and post-inflammatory hyperpigmentation (PIH). It works by inhibiting the enzyme that produces melanin, the pigment that gives our skin its color.
3. Anti-Aging: Azelaic acid has antioxidant properties that help to protect the skin from damage caused by free radicals. It also helps to stimulate collagen production, which can reduce the appearance of fine lines and wrinkles.
4. Rosacea: Azelaic acid has been approved by the FDA for the treatment of rosacea. It works by reducing inflammation and redness in the skin.
Azelaic acid is a versatile ingredient that can benefit many different skin concerns. It is generally safe for all skin types but may cause some irritation in those with sensitive skin. It is always best to patch test a new product containing azelaic acid before using it all over the face.
