5 Ways To Make Your Underarms Smoother & More Even-Toned

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. 

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. 

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. 

"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. 

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.
