What’s the Difference Between Physical and Chemical Exfoliants, and Which Is Better?

We asked four top industry experts to weigh in.

With time, dead skin cells build up on the surface of our faces and can cause breakouts, clogged pores, and dull skin. If you’re anything like us, that doesn’t really align with that whole glowy skin vision we have for ourselves—so we know that exfoliation is key. Exfoliating helps slough off dead skin, and it also allows our serums and moisturizers to sink in better. At our best, we’re exfoliating regularly (say, twice a week), and we’re using one of two types of exfoliants: chemical or physical.

But with so much information out there regarding chemical vs. physical exfoliants and best exfoliation practices, things can get overwhelming. No worries, though: We talked to some experts and got the lowdown on the difference between the two types and when to use them. We even got a list of dermatologist- and skin expert-approved products to help you get that ever sought-after glowy skin.

What is chemical exfoliation?

If you’re new to exfoliating, don’t let the sound of a chemical exfoliant scare you—it’s not as harsh as it seems. According to celebrity esthetician Shani Darden, chemical exfoliants are the kind that use acids (such as lactic acid, glycolic acid, citric acid, salicylic acid, etc.) to gently dissolve away dead skin cells from the top layer of the skin. Dendy Engleman, M.D., a board-certified dermatologist in New York City, explains that chemical exfoliants work to break down the cellular bonds of dead skin cells rather than physically buffering away the top layer of dead skin.

What is physical exfoliation?

A physical exfoliant is probably what you usually think of when you think of exfoliation. It’s the kind that physically removes dead skin cells via a mechanical tool or scrub. Maya Crothers, founder of Circcell Skincare, adds that physical exfoliants are the kind that use particle friction to remove skin cells, like sandpaper resurfacing wood (but much softer, obviously).

What type of exfoliation is better for the skin?

According to Tiffany Libby, M.D., a board-certified dermatologist in Manhattan, both chemical and physical exfoliants have their pros and cons. And, as Crothers advises, choosing one method over the other has more to do with what your skin can tolerate.

A pro for using a physical exfoliant is that you can control the amount of pressure used to better suit your skin’s sensitivity level, per Crothers’ advice. However, it’s worth mentioning that physical exfoliants require a certain level of caution. Dr. Libby warns that some physical scrubs contain larger, more abrasive particles that can cause micro-tears to the skin, leading to irritation and even inflammation.

Most of our experts prefer chemical exfoliants over physical. According to Dr. Libby, chemical exfoliants are often overall safer, more controlled, and, in her experience, more effective with regular use. Plus, chemical exfoliants can help minimize and treat acne as well as even out your skin tone for a glowy and bright complexion. Darden echoes this, summarizing that chemical exfoliants are often more effective and yet less harsh.

When should we choose one over the other?

For your face, Dr. Engelman suggests using a chemical exfoliant. However, if you’re looking to exfoliate your body instead of your face, she suggests going for a physical exfoliant, especially if you’re dealing with ingrown hairs.

For regular use, the overall consensus is to choose a chemical exfoliant over a physical one, as manual exfoliation can be too harsh on some skin types. Darden does recommend, however, using a physical exfoliant if you haven’t taken care of your skin in quite some time and are looking for a quick “polish,” but also suggests using a chemical exfoliant every week.

These are the best exfoliants for your face and body:

If you’re going down the physical exfoliant route, it’s perhaps best to go for a gentle scrub. Dr. Libby recommends this one, which uses fine microparticles from bamboo extract to buff away dead skin without stripping your skin of its moisture.
