Benefits of Exfoliation
Your body sloughs off dead skin cells naturally. "Our body is always shedding skin to replace with new skin cells. However, when this process is slowed down or interrupted, dead skin cells can build up on the skinâ€™s surface and appear dull and flaky," says Gohara.
Exfoliating also amps up the skin's ability to absorb your skincare products, says Tobia. Otherwise, you risk products just sitting on top of a layer of dead skin cellsâ€”and that doesn't sound like a good use of your favorite body oil at all. Exfoliating "not only will it brighten up your complexion, but it will also prevent any acne breakouts caused by clogged pores," says Gohara.
Bonus: If you're proactive about exfoliating regularly in the shower, you might reduce some of the dust pollutants in your house.
How Often Should You Exfoliate?
Even though you shed dead skin cells daily, there's no need to exfoliate every day. In fact, doing so could strip your skin of its natural moisture. According to Dr. Joshua Zeichner, there are two common forms of exfoliation: "Chemical exfoliation is the use of hydroxyacids to dissolve connections between cells so they can be more easily shed. Physical, or manual, exfoliation is the process of directly removing cells using a gritty surface."
For best results, exfoliate two or three times a week. If you have sensitive skin, stick with once a week.
Bottom line: Exfoliating might help reduce the amount of dust in your home, but the biggest benefit is getting to maintain smooth, healthy-looking skin. Kinda makes you forget all about the dead skin cells collecting under your bed.
Ahead we break down expert tips for removing dead skin cellsâ€”and the best products to shop for at-home exfoliation.
When it comes to exfoliation, you've got options. Scrubs are an especially popular choice. These products work their magic through "beads or particles that offer manual exfoliating benefits," explains Zeichner. Many scrubs contain beads made from silica or jojoba or powders derive from botanical sources like rice or bamboo.
Sugar or salt body scrubs are loved for buffing skin to perfection while making exfoliation feel more like an indulgence than a chore. The promise of soft, smooth skin is a pretty good motivator, too.
Coffee scrubs like Frank Body Original Coffee Scrub ($17) are nourishing because of antioxidant-rich ingredients like almond oil and protective, healing vitamin E.
One area of your body that's easy to overlook (but still contains plenty of dead skin cells) is the scalp. If you're dealing with dry flakes, a scalp scrub can be a luxurious and effective way to exfoliate. Plus, it can help cleanse and remove product and styling residue. Dual-actionâ€”what's not to love.
The Cristophe Robin Purifying Scalp Scrub with Sea Salt ($53) is a beauty cult classic for a reason. The formula works as both a shampoo and an exfoliator, leaving your hair and scalp happy after one shower.
Manual Sponges, Poufs, and Gloves
A simple fix is adding manual exfoliation to your shower routine. This method is pretty simple and can be performed using brushes, sponges, or devices, says Zeichner. Even adding a washcloth to your body routine can help shed excess skin cells.
"I use a poof myself, and itâ€™s always my go-to suggestion for manual exfoliation, as it isnâ€™t as harsh and doesnâ€™t contain as much bacteria as a loofa," says Gohara. Another alternativeâ€”if you'd rather not use a sponge or poofâ€”are exfoliating gloves. Most are machine washable, so it's easy to give them a regular cleaning.
Celebrities like Tracee Ellis Ross and Gwyneth Paltrow swear by dry brushingâ€” an ancient Ayurvedic technique that has become a wellness phenomenon in the last few years. With a long wooden handle and stiff natural bristles, a dry brush is meant to be used to massage your entire body from your feet all the way up to your shoulders. No water needed.
"Dry brushing is another alternative if you rather not exfoliate in the shower," says Gohara. However, she notes that this method should only be done 1x a week "and on healthy, unbroken skin." It's also especially effective during dry, winter months when your skin might need a little bit of extra love.
Not only does dry brushing exfoliate, but it can also stimulate new cell growth, promote lymphatic drainage, and even temporarily minimize the look of cellulite.
On the chemical front, "acids" are a skincare category you'll want to explore. According to Lamb, glycolic (AHA) and salicylic acids (BHA) are what you should look for on your ingredient lists. "Products with AHAs and BHAs are an amazing way to promote skin cell turnover. They make the top layer of the skin softer so that the cells turn over easier."
Zeichner also recommends considering your skin type when adding a chemical exfoliant to your routine. AHAs work well for aging skin concerns. SkinMedica's AHA/BHA Exfoliating Cleanser ($47) contains both acids as well as jojoba spheres that help exfoliate skin and enhance skin texture. This gentle exfoliating cleanser helps scrub away dead skin and brighten up your complexion.
The go-to for acne-prone skin? Beta Hydroxyacids (like salicylic acid) "are oil soluble and penetrate into the follicles," says Zeichnerâ€”so, they're great for anyone with high oil production. Also, "Polyhydroxy acids can be used even in people with sensitive skin because they are ultra-gentle," adds Zeichner.
Lamb likes Charlotte Tilbury's Super Radiance Resurfacing Facial ($70), which is a weekly treatment and one of her "favorite products for providing these benefits without stripping the skin of natural oils."
A chemical peel is a high-octane version of exfoliation (and is best done with a dermatologist or licenses aesthetician). "With the combination of both at-home products and in-office treatments, it can help aid in the continued improvement of the skin as exfoliated skin is much more receptive to absorb product," explains Tobia.
However, there are a few overnight peels you can buy that are gentle enough to use at home. Zeichner recommends the Bliss Thatâ€™s Incredi-Peel Spa-Strength Glycolic Resurfacing Pads ($24). They contain 10% glycolic acid, which he adds "can improve skin radiance, and thereâ€™s also data showing that he can help improve the appearance of fine lines and wrinkles."
Your skin sloughs off dead cells naturallyâ€”your body is always shedding skin to replace. However, dead skin cells can build up on the surface, which can make your skin look dull and flaky.
Dead skin cells will shed naturally, but to speed up the process, experts recommend manual or chemical exfoliants.
Exfoliants remove dead skin cells. You can use a chemical exfoliant, which often takes the form of acids (like AHAs and BHAs), which are active ingredients found in many skincare products. Physical (or manual) exfoliation is another option using a srub, sponge, or another device.
