What’s an AHA?

An AHA is a chemical exfoliator that can help improve the appearance of skin texture and tone with continued use over time. Ethnic skin expert, and Skincare.com consultant, Dr. William Kwan recommends an AHA for those looking to reduce the appearance of fine lines, wrinkles, and sun damage. AHAs are water soluble with a small particle size, and the most popular include glycolic, lactic and citric acids.

What’s a BHA?

 A BHA is a chemical exfoliator that can be found in a wide range of different products, including cleansers, toners, and moisturizers. BHAs are oil soluble with a large particle size that “can rest on pores and can help with acne,” according to Dr. Kwan. If you have oily or acne-prone skin, you’ve probably used this uber-popular BHA without even knowing it—salicylic acid.

While there are products that feature AHAs and BHAs separate of one another, there are others that combine the two. Scroll through for some of our favorite products—from the L’Oreal portfolio of brands—formulated with both AHAs and BHAs!

Editor’s note: AHAs and BHAs can cause unwanted skin dryness or irritation especially on sensitive skin types, who should avoid the combination. As a general rule of thumb, be careful not to over-exfoliate your skin by carefully following the instructions for use listed on your product of choice. Also, AHAs and BHAs can increase your skin’s sun sensitivity. When outdoors, apply broad-spectrum sunscreen and reapply at least every two hours. Take additional sun protection measures such as seeking shade, wearing protective clothing, and avoiding peak sun hours.
