Why You Should Exfoliate Your Underarms

Your skincare routine shouldn’t stop at your jawline. You wouldn't skip moisturizing your face, so why are your underarms being left out? Just like the rest of your skin, your underarms collect sweat, dead cells, bacteria, and product buildup—think deodorants and antiperspirants that never fully rinse away. Skipping exfoliation in this area can lead to clogged pores, bumps, uneven tone, and even an odor that lingers longer than it should.

Why you should be exfoliating below the sleeves
Underarm skin has a lot going on. It's warm, often damp, and sees a lot of friction. Add shaving and thick deodorant formulas into the mix, and you've got a recipe for trapped hair, irritation, and hyperpigmentation. Exfoliating helps by lifting away the gunk—dead cells, sebum, and debris—that can clog hair follicles and lead to ingrown hairs or body odor that persists no matter how much you wash.

Dermatologists and beauty experts stress the benefits of keeping this skin fresh. Regular exfoliation helps prevent bumps, scarring, and discoloration, especially in people who shave often.

The right way to exfoliate your underarms
Forget scrubbing with harsh grains or overly fragrant body scrubs. The skin here is thinner and more sensitive than, say, your elbows or heels. Go with something gentle, like a glycolic acid toner or even a natural skincare brand's exfoliating pads. These chemical exfoliants work by dissolving the glue that holds dead skin cells together—no physical abrasion is needed.

A good rule: exfoliate 2–3 times per week, and always follow up with hydration. This area needs moisture just like your face does, especially post-shave. Your favorite moisturizer or luxury airless skincare product with a lightweight formula can double as an underarm hydrator if you want to streamline your routine.
