Skin discoloration doesn't just happen on your face—it can sneak up in unexpected areas, like your underarms. This can leave the skin looking uneven and darker than the rest of your body. So, what gives? From your razor habits to the products you use, there are a surprising number of reasons why underarm discoloration occurs. Here's the lowdown on what might be causing it and how to address it.
Why do underarms turn dark?
Shaving and friction
Shaving might seem like a quick fix for underarm hair, but it's also a sneaky culprit behind discoloration. Constant friction from razors can irritate the skin, leading to inflammation and hyperpigmentation. This irritation worsens if you're dry shaving or skipping out on a quality shaving gel. Plus, the leftover hair under the surface can create a shadowy appearance.
To prevent this, opt for a hydrating shaving gel or cream to minimize friction, and switch to a gentler routine. Pair this with a skin toning lotion post-shave to calm and hydrate irritated skin.
Dead skin build-up
A build-up of dead skin cells in your underarm area could also be at play. This dull layer can exaggerate discoloration, especially in areas prone to sweating and friction. Experts suggest reaching for gentle exfoliating products. A natural body scrub can work wonders in sloughing off dead skin and revealing smoother, brighter underarms.
Irritation from deodorants
Not all deodorants are created equal. Some formulations may contain harsh ingredients that irritate sensitive underarm skin, triggering inflammation and dark spots. Switching to clean beauty products or formulas designed for sensitive skin care can help keep irritation at bay.
Tight clothing
Those trendy, fitted tops may not be doing your underarms any favors. Tight shirts can rub against the skin, causing discoloration over time. Swapping in breathable, loose-fitting fabrics can reduce friction and give your skin a break.
Sun exposure
Yes, even your underarms need sun protection! UV rays can stimulate melanin production, darkening exposed skin. Adding sunscreen to your routine—even in areas you don't think about—can help prevent further pigmentation issues.
How to prevent dark underarms
(1) Upgrade your shaving routine. Switch to high-quality razors, and always use a shaving gel or cream. Follow up with a soothing natural moisturizer for dry skin to keep the area soft and irritation-free.
(2) Exfoliate. Consistent exfoliation can help remove the build-up of dead skin cells. Look for a mild exfoliating scrub to gently brighten the area without over-drying.
(3) Wear sunscreen. Invest in a lightweight, non-comedogenic sunscreen to protect your underarms from UV rays. Think of it as an essential step in your best natural skincare routine.
(4) Consult a dermatologist. If your underarm discoloration persists despite your best efforts, it might be time to see a professional. Dermatologists can recommend treatments, such as skin-whitening products, to tackle pigmentation concerns.
