Summer is the season of tank tops, sleeveless dresses and suddenly being very aware of your armpits in a way you weren't in January.Dark underarms are one of those concerns that people rarely talk about openly but search for constantly, usually right before a beach trip or a wedding where bare arms are unavoidable. If you've noticed your underarms looking darker, dull or uneven and assumed it was just something you had to live with, a board-certified dermatologist would like a word.Here's what's actually happening. Underarm skin is some of the most stressed skin on your body. It deals with daily shaving or waxing, friction from clothing, layers of deodorant and antiperspirant buildup, sweating and constant movement. Dr. Alicia Zalka, board-certified dermatologist and founder of Surface Deep, explains that the skin responds to all of that irritation by thickening and producing more pigment as a form of self-defense.
If your darkening seems sudden, extensive or is accompanied by velvety thickening of the skin, see a doctor before reaching for brightening products.To find the best treatments, we talked to four dermatologists—Dr. Zalka, Dr. Ponzo, Dr. Kazlouskaya and Dr. Zamani—about what's actually driving underarm darkening and which products are worth your money.Related: If You Skip Deodorant for a Week, Here’s What Happens to Your Body

First things first: "Before reaching for brightening products, I recommend restoring the skin barrier with a gentle moisturizer and eliminating anything that may be causing irritation," Kazlouskaya tells Parade.
Ponzo adds that for more stubborn pigmentation, ingredients like hydroquinone or tretinoin may be appropriate under physician supervision.

How Long Does It Take for Armpit Brightening Treatments To Work?
Yes, for most cases. Kazlouskaya's at-home protocol is practical. Use a moisturizer containing ammonium lactate, avoid fragranced deodorants, minimize friction from shaving or tight clothing and consider speaking with a primary care physician about screening for insulin resistance if the darkening is new or accompanied by velvety texture changes. Zamani adds that switching to fragrance-free deodorants, improving shaving technique and reducing friction can make a significant difference in preventing discoloration from recurring.

How To Get Rid of Dark Armpits: 9 Best Underarm Brightening Treatments
Here are the underarm brightening treatments recommended by dermatologists—including the most affordable option lower in the list, which can be used in the shower.
Best Multitasker: CeraVe Skin Renewing Night Cream, $22
Amazon
Shop It on AmazonZalka loves this CeraVe Night Cream because it works for so many skin concerns—the formula addresses both the barrier damage and the pigmentation component of dark underarms. She says it "soothes and brightens with ceramides and niacinamide.” A powerful combo! Plus, the overnight format means it has uninterrupted time to work without competing with deodorant, and it's widely available, well-priced and gentle on a sensitive area. It’s a win-win-win.
Best Serum: Eucerin Radiant Tone Dual Serum, $40
Amazon
Shop It on AmazonKazlouskaya calls this one of her current favorite pigment-correcting products, and the star ingredient is thiamidol. "Thiamidol has excellent data for reducing hyperpigmentation while being gentler than many traditional lightening agents, making it suitable for most skin types," she says. The hyaluronic acid in the formula supports barrier repair at the same time, which addresses both components of the darkening cycle simultaneously.
Best Brightening Deodorant: Dove Even Tone Antiperspirant, $9
Amazon
Shop It on AmazonPonzo's pick solves the practical problem that most brightening routines ignore. If your daily deodorant is contributing to irritation and pigmentation, no serum is going to fully counteract what you're applying every morning. This formula "helps prevent irritation while improving tone over time," she explains—meaning it works on the cause of darkening rather than just the symptom. Switching your everyday deodorant is one of the highest-leverage changes you can make.
Best for Sensitive Skin: AmLactin Daily Nourish Body Lotion, $12
Amazon
Shop It on AmazonKazlouskaya recommends this as a first-line option specifically because it multitasks without irritating. "It hydrates while providing gentle exfoliation," she says. "It works gradually, but it's affordable, well tolerated and helps repair the skin barrier at the same time." For sensitive underarm skin that reacts to stronger actives, the gentle lactic acid approach here is the place to start before introducing anything more targeted.
Best Affordable: Olay Tone Correcting BHA and Vitamin C Body Wash, $11
Amazon
Shop It on AmazonZalka calls this cult-favorite beauty brand out in the best way for "starting armpit color correction in the shower." The BHA exfoliates while vitamin C works on pigmentation, and because it's a body wash, it integrates into a step you're already doing daily without adding anything to your routine. For anyone overwhelmed by the idea of a dedicated underarm skincare routine, this is the most accessible entry point.
Best for Dark Skin Tones: Nécessaire The Body Vitamin C-Radiance Serum, $62
Amazon
Shop It on AmazonZamani emphasizes that deeper skin tones require particular care with brightening treatments, since aggressive ingredients can trigger additional post-inflammatory pigmentation rather than reducing it. A well-formulated vitamin C serum like this one addresses hyperpigmentation through antioxidant activity rather than direct irritation, making it a safer choice for skin that's already prone to inflammation-driven darkening. Zalka also calls it out for its "luxury and lightening" combination.
Best for Travel: Surface Deep Pads, $22
Amazon
Shop It on AmazonThese pads "swipe away residue from other products, exfoliate and brighten with glycolic, soothe with postbiotic ferments," she explains. For underarm skin that has been layered with products daily for years, clearing the decks before brightening is half the battle.
Best Exfoliant: Glytone Enhance Brightening Serum, $79
dermstore
Shop It at DermstoreKazlouskaya's exfoliant pick combines kojic acid and azelaic acid, a pairing she finds "very effective for post-inflammatory pigmentation." Because the underarms are sensitive, she recommends introducing it slowly and reducing frequency if irritation occurs. Ponzo also recommends azelaic acid formulas specifically for stubborn pigmentation, noting that it "targets melanin production for more resistant dark spots."
Best for Post-Shave Darkening: La Roche-Posay Mela B3 Dark Spot Corrector, $45
Amazon
Shop It on AmazonZalka's recommendation is similarly concise: "Nothing harsh, just helps dark marks," she says—which is exactly the brief for skin that's already been through the repeated micro-trauma of regular shaving.
