Why are my armpits dark?

It’s a hidden mystery, and everyone wants to know the real cause of this problem. You are not alone in this phase. Many people suffer from dark skin tones and are concerned about why their underarm areas get dark. So here, we have disclosed some of the crucial factors that affect your underarm discoloration.

Excessive shaving and waxing

Constant use of shaving cream and frequent waxing are common causes of dark underarms. Shaving and waxing are exfoliating practices that can irritate the skin since they remove the outermost layer of skin. Armpit discolouration is a common side effect of improper shaving.

Wrong use of Deodorants and antiperspirants

The improper use of irritating deodorants and antiperspirants is the root cause of this uncomfortable issue. Certain chemicals in deodorants and antiperspirants have been linked to skin darkening in sensitive individuals.

Disruptive Hormonal Changes

Hormonal imbalances are another possible cause of underarm discolouration. Hormonal changes during puberty, pregnancy, and menopause can cause an increase in melanin production, which can result in skin darkening.

Unwanted friction

Friction is a common contributor to underarm discolouration. Skin irritation and hyperpigmentation can result from too much friction between the skin’s surface layers. This is especially common in people who are overweight or who participate in sports or manual labour that require frequent use of the arms. Many people also wear tight-fitting garments, which can irritate the skin and lead to excess melanocyte production, discolouration, uneven skin tone, and skin tags. 

Several pathological conditions

Everyone should know the secret chemistry behind the question, “Why are my armpits dark?”. Dark underarms might sometimes be a symptom of a more serious health problem. Dark patches and skin thickness, called malignant acanthosis nigricans, is a condition that can affect the armpits.

Uneven skin colour can be a result of diabetes as well. High blood sugar can cause insulin resistance, which can increase melanin production, resulting in hyperpigmentation or darkening of the skin.

You should see a doctor if you notice any unwanted black patches; they can diagnose and treat the problem.

Why do underarms get dark during pregnancy?

As a woman’s body undergoes unbelievable transformations during pregnancy, it’s no surprise that some changes are welcomed with open arms while others may not be as exciting. The miracle of new life growing inside her is unique, but some changes can be more challenging. Did you know that some women experience a change in the colour of their underarms? It’s true! This can be a common occurrence for many women.

The female body goes through numerous changes in hormones while pregnant. The body may react in various ways to these hormonal disorders, including increased melanin production. When the production of melanin increases, which is responsible for the colour of our skin, can cause discolouration in the armpits.

Friction is another possible cause of dark underarms during pregnancy. As the baby grows and the mom’s tummy gets heavier, she may feel herself constantly rubbing her arms against her sides. Due to irritation and post-inflammatory hyperpigmentation, black spots may develop on the skin due to constant rubbing. 

How to prevent dark underarms

Why are my armpits so dark? Many people find it annoying and humiliating to deal with underlying conditions. How to get smooth armpits? This is something everyone is always looking for. Several things can cause underarm discolouration, but luckily, there are plenty of ways to stop it. Here we will discuss easy and productive ways to avoid dark underarm skin and help you to preserve a youthful glow.

Maintain proper hygiene

My armpits are dark. What should I do? The very first thing you can do is to practice good hygiene. This means washing your underarms daily with gentle soap and water and thoroughly drying them afterwards.

Avoid harsh chemicals

Chemicals like brightening cream in many commercial deodorants and antiperspirants irritate the skin and speed up the developing of dark underarms. So why are my armpits dark all of a sudden? It is because of harsh chemicals. You should try using a natural deodorant or antiperspirant instead of one with artificial ingredients to avoid this skin condition.

Moisturize regularly

How to get rid of discoloration? Don’t panic! Moisturizing daily can help you prevent dark armpits, and you will gradually get rid of discoloration. Keep your underarms hydrated since dry skin conditions are more prone to discoloration. After you get out of the shower or bath, apply a light moisturizing lotion to your underarms.

Always remember to exfoliate!

Exfoliating once or twice weekly is recommended to avoid forming new black spots. Be careful not to scrub too vigorously to exfoliate dead skin cells, or your skin may become even more inflamed.

Put on loose, airy garments

Underarm dark spots may be exacerbated by sweat retention under synthetic or close-fitting clothes. Wearing tight-fitting clothes restricts circulation and should be avoided.

Keep an eye on the diet.

My underarms are very black, don’t worry, watch your diet. Coffee and other caffeinated drinks, and spicy foods have been linked to increased perspiration and skin darkening. Reduce these foods and drinks to avoid dehydration and increase your water intake.

Avoid shaving

Shaving can irritate the skin and lead to the formation of ingrown hair, which can contribute to darkening. Consider using a depilatory cream or waxing instead to reduce underarm irritation.
