The Best Anti-Aging Ingredients on the Market, According to Science

Alpha Hydroxy Acids (AHAs) and Beta Hydroxy Acids (BHAs) work by exfoliating away dead skin cells to reveal a complexion that's brighter, smoother and more youthful. "This process also helps active ingredients to better penetrate the skin so you can benefit more from your products," explains board-certified dermatologist Dr. Dendy Engelman.

There are many types of AHAs, including glycolic acid, lactic acid and mandelic acid, and they help with issues like pigmentation and texture. There's one primary BHA in skin care, salicylic acid, and its primary function is to target blemishes and post-inflammatory hyperpigmentation.
