Ingredient N° 15
A versatile option for blemishes, redness and marks.
Azelaic acid is used in formulas targeting blemishes, visible redness and post-blemish marks. It is often easier to combine than stronger exfoliating acids, though comfort still depends on concentration and the rest of the formula.
Worth knowing
Tingling and dryness can occur at first; start slowly and moisturize.
