7 Best Armpit Brightening Creams in 2024, Tested & Reviewed

There are also medical conditions, like acanthosis nigricans, which can lead to underarm hyperpigmentation. “This condition can result in dark and thickened skin, typically in body folds such as the armpits, neck, and groin,” says Dr. Amin. “Acanthosis nigricans is often associated with insulin resistance, obesity, and type 2 diabetes. High insulin levels trigger skin cells to reproduce more rapidly, leading to dark thickened plaques.”

How can you minimize underarm discoloration?

Good news: There are quite a few over-the-counter avenues you can take to improve your pits’ skin tone. “Several skin-care ingredients can help reduce underarm hyperpigmentation by lightening dark patches and promoting even skin tone,” says Dr. Amin. The best armpit brightening cream will contain retinol or exfoliating acids, such as glycolic, salicylic, and lactic acids, for their brightening properties.

“Regular exfoliation combined with brightening agents can help improve the appearance of underarm hyperpigmentation over time,” she says. However, when using active ingredients like exfoliating acids and retinol, Dr. Amin says it’s important to introduce them gradually and, if you’re exposing skin during daylight hours, always follow up with sunscreen, as they can increase photosensitivity.

How we test and review products

When Allure tests a product, our editors look at it from every angle in an effort to best serve you. We review ingredients, scrutinize brand claims, and, when necessary, examine peer-reviewed scientific and medical studies. In addition to testing each and every product that’s included in each and every review, we rely on experts who shape their fields, including dermatology, cosmetic chemistry, and medicine, to help us vet the ingredients and formulas.

For our list of the best armpit brightening creams, we considered each product’s performance across five primary categories: product ingredients and efficacy, packaging, fragrance, texture, and product wear. Every product was determined to have excelled in each category by our editorial team, which is composed of in-house writers and editors as well as contributors—along with special consideration from board-certified dermatologists.
