5 Ways To Make Your Underarms Smoother & More Even

Jun 24, 2023Jun 24, 2023

Underarms seem to be a new focus point for skin care fans, with many folks incorporating additional serums, moisturizers, and shaving tools in pursuit of smooth, bright pits.

Even as a skin care lover myself, I have to ask: Do we really need a skin care routine for our underarms? I passed this question to dermatologists for their best tips so you can reap these benefits in a minimalist fashion:

This tip isn't new, but it's something every expert has told me: You need to prioritize a clean, sharp razor. "The sharper the blade, the cleaner the cut, which prevents any bumps," says board-certified dermatologist Margarita Lolis, M.D.

You'll know your razor is too old if it scratches against your skin, or if it's been more than three or four weeks since you've swapped the blade.

You should also actively clean your razor after every use, Lolis says. Cleanse it with soap, pat it dry with a towel, and store it in a dry environment (read: not in your steamy shower). This prevents rusting, dullness, and microbial growth that could lead to infection, she notes.

While you may be used to switching up your facial skin care routine, you might ignore emerging products in this niche area of body care. However, many modern formulas cushion a shave better than fluffy creams of years past.

One of my favorite methods: using a shave bar or shave stick, like the WYOS Shaving Suds or Hanni Shave Pillow. The formula acts like a rub-on shaving cream for a no-mess experience.

You can also try using simple oils, like jojoba, grapeseed, or rosehip oil, in the shower to shave if you want even more slip.

"I recommend using a gentle deodorant that doesn't have irritating ingredients in it, such as the Miles Clean Deodorant," says board-certified dermatologist Jeannette Graf, M.D., FAAD.

Which format you use (spray, serum, stick, etc.) is up to you, but try to avoid super-heavy deodorant formulas, as they may clog your pores and result in more unwanted texture.

For those concerned about underarm hyperpigmentation, let's talk about the viral glycolic acid hack: a process that entails applying a glycolic acid toner (most often The Ordinary Glycolic Acid 7% Exfoliating Toning Solution) to lighten hyperpigmentation and exfoliate the underarm area.

Many folks on TikTok praise this affordable product for transforming their underarms, but do dermatologists back this step?

According to Lolis, it's a worthy addition. "[Glycolic acid] works by breaking up dead skin cells and lowering the pH of the skin, which decreases the bacterial load," she explains. And reduced bacteria often means reduced underarm odor.

Plus, "Glycolic acid has the added benefit that it reduces hyperpigmentation," she says. But here's the thing: You shouldn't use just any product out there. Lolis recommends seeking a glycolic acid product with a less than 10% concentration, making the viral product above a worthy investment.

Use this toner under your arms once or twice a week (rather than daily) to minimize the chance of irritation from over-exfoliation. Of course, if you're sensitive to the potent AHA, feel free to skip this step.

Finally, consider an aftershave product if you don't use one already. "Applying moisturizer to the area can help overall skin health. The underarm skin is a sensitive area, so it's best to give [it] extra care," Graf explains.

Be sure to skip anything with too much fragrance, any kind of exfoliant, or retinol, as that will irritate your freshly exfoliated skin. Instead, keep your moisturizer simple and hydrating.

My favorite product for this purpose is the mindbodygreen dry body oil, because you can use it on sensitive areas, and it helps to prevent razor bumps and ingrown hairs—plus, it sinks into the skin in seconds. You can also use a lightweight body lotion or a simple noncomedogenic botanical oil, like jojoba, grapeseed, etc.

Wait for that product to dry, then follow up with your deodorant. Otherwise, you'll be left with a creamy mess begging to transfer onto dark-colored clothing.

Beyond that, any serums or tricks may be considered extra. Still, go with what works for your own skin, and remember: You don't have to do any of these steps if you don't want to. Your underarms will remain in good health with a simple daily wash, too.

If you want smoother underarms, it starts with using a clean razor. Be sure to exfoliate, apply a pre-shave moisturizer, hydrate the skin afterward, use clean deodorant, and consider a glycolic acid treatment for occasional use. In search of a new razor?
