What causes dark armpits?

There’s more than one reason why your armpits may be darker than the rest of your skin. Some common causes include shaving, hyperpigmentation, dead skin cells, and deodorant. Let’s take a closer look at each one to learn more.

Shaving and hair removal
Skin may darken if the skin cells multiply faster than they normally do or should. This is common around areas where you shave or otherwise remove hair from the body — armpits being a common place. In addition, when hair regrows, stubble and new growth can make the skin appear darker. Even though it’s just hair pushing through the follicles. Many people call this a “five o’clock shadow” when it happens on a man’s face. But it can happen in other places, like underarms.

Hyperpigmentation
Hyperpigmentation is another common reason why you have dark armpits.. And there’s more than one reason why hyperpigmentation develops. Sometimes it’s because of irritation. Sometimes it’s because of shaving, like we talked about earlier. And sometimes it’s because of underlying conditions like acanthosis nigricans, diabetes, or even injury.

Dead skin cell accumulation
Where skin folds, it can hide skin cells away from exfoliation and cleansing. Over time, those skin cells die and accumulate — like dust. This accumulation can clog pores, leading to blackheads, infection, and even unpleasant odor. And, it can lead to darkened skin, because of increased pigmentation.

Deodorant
Many deodorants use aluminum salts to help manage perspiration and odor. Over time, these deodorants can dry out the skin, leave behind dead skin cells, and clog pores — all of which can cause darker underarms.

For some people, aluminum deodorants can also cause skin irritation and damage, leading to post-inflammatory pigmentation.

how to get rid of dark armpits

If you want to get rid of stubborn dark underarms, you’ve got options. Some common solutions include OTC skincare products, natural remedies, and natural deodorants. So let’s explore each one in depth.

Skincare products
Glycolic acid, lactic acid, sea salt, spirulina, and even lemon peel can help lighten dark armpits — and target dark underarms. The trick is finding products with those kinds of ingredients. We recommend the Dark Spot Treatment Duo bundle because not only does it have all those helpful ingredients, but it’s also rich with nutrients to support skin health. The Dark Spot Treatment Duo is designed to lighten, brighten, and smooth as it exfoliates, revealing healthier, supple skin.

Exfoliate regularly
Just like chemical exfoliation, physical forms of exfoliation (like scrubs and microdermabrasion) can help get rid of dead skin cells, a common cause of dark underarms. Loofahs, washcloths, and microbeads can exfoliate the skin to reveal a healthy glow. But don’t overdo it. Over-exfoliating can strip away the skin’s natural oils leading to dry skin and clogged pores. Instead, try gentle exfoliation with a coffee scrub (like this anti-cellulite coffee scrub) to awaken the skin, cleanse the underarms, and keep cellulite at bay while you’re at it.

Use natural remedies
Some sources suggest that natural remedies like potatoes, milk, rose water, turmeric, coconut oil, and yes, even egg yolks can help lighten the skin. This might work for you, and it might not. Like most home remedies, your mileage may vary and be wary of allergens if you’re prone to reactions. If natural remedies don’t work for you, try gentle exfoliation and OTC products like we mentioned earlier. And if you’re not sure, consult with a dermatologist for recommended ingredients and products.

Switch to natural deodorants
Although aluminum deodorants are known for their effectiveness, natural deodorants may be a better choice if you have sensitive skin — especially in your pits.

Instead of drying your skin out, natural deodorants often use ingredients like shea butter, coconut oil, baking soda, and vitamin E to moisturize and hydrate. This can prevent dead skin cell buildup, and reduce irritation if you’re sensitive to traditional deodorants.

Tips for maintaining healthy underarms

Healthy armpits are happy armpits! And a regimented hygiene routine may help prevent or reduce hyperpigmentation in the underarms. Here are some tips to develop and maintain healthy underarms.
Moisturize and hydrate
Moisturize. Hydrate. Repeat.
Dry skin can feel irritated and cracked, which can lead to dead skin cell accumulation and even infection in more severe cases. So keep those underarms hydrated with moisturizers and drink plenty of water. Your skin will thank you.
Everton Skin is here to revolutionize your skincare routine with our exceptional dark spot treatment duo. At Everton Skin, we understand the importance of having healthy, radiant skin. Dark armpits can often be a source of frustration and self-consciousness, but with our advanced formula, you can confidently say goodbye to those pesky marks.

Avoid irritation
Irritation and inflammation are top offenders when it comes to armpit hyperpigmentation. When you keep irritation away, your underarms are healthier, and less likely to darken. Think about chemical and physical irritants, and then try to reduce them. For example, some people notice irritation after shaving. Others notice it with certain deodorants. And even simple things like tank tops and short sleeves can irritate the underarms.

Protect your skin from the sun
Yes, the sun can cause hyperpigmentation — even in your armpits. If you spend a lot of time outside (whether you suntan or not), consider wearing longer sleeves to protect your underarms and always apply sunscreen. Remember to reapply sunscreen every hour (or more frequently depending on the brand). And if you sweat or go swimming, you may need to reapply more often as well.
