Here’s another natural skincare ingredient to watch out for: azelaic acid (AA). It has some things in common with salicylic acid, which you might have used to help clear up an uneven skin tone. AA can also help prevent breakouts, but AA seems to be even better for reducing hyperpigmentation, rosacea and other issues related to inflammation in your skin. It can also help improve tone, reduce redness, exfoliate and help reduce the signs of aging and dark spots. Look out of products with AA in for all the above benefits.
