Darken underarms are a common cosmetic concern for many. They can be embarrassing and affect one's self-confidence. The darkening of the skin under the armpits can be caused by a variety of factors such as shaving, excessive sweating, and the use of certain products.

In this article, we will discuss the causes, treatment, and prevention of darkened underarms.


Causes of Darken Underarms

Shaving: Shaving the underarms can cause the skin to darken. When you shave, you're not only removing hair, but you're also removing a thin layer of skin. This can lead to skin irritation, inflammation, and darkening of the skin.

Excessive sweating: Sweating is a natural process that helps regulate body temperature. However, excessive sweating can cause the skin under the arms to darken.

This is because sweat mixes with bacteria on the skin and produces an odor. The chemicals in the sweat can also cause skin irritation, which can lead to darkening.

Use of certain products: The use of certain products such as deodorants and antiperspirants can darken underarms. Deodorants and antiperspirants contain chemicals that can cause skin irritation and darkening.

Medical conditions: Certain medical conditions such as acanthosis, nigricans, and diabetes can cause darkened underarms. Acanthosis nigricans is a skin condition that causes dark patches on the underarm to develop. Diabetes can darken underarms due to changes in hormone levels.

Exfoliate: Exfoliating the skin under the arms can help remove dead skin cells and promote new cell growth. This can help lighten the skin under the arms. You can use a loofah or an exfoliating scrub to gently exfoliate the skin.

Use skin lightening products: There are various skin-lightening products available in the market that can help lighten darken underarms. These products contain ingredients such as kojic acid, arbutin, and vitamin C that can help reduce skin pigmentation.

Stop using certain products: If you suspect that your deodorant or antiperspirant is causing darken underarms, stop using them. Try switching to a natural deodorant or antiperspirant or stop using them altogether.

Medical treatment: If your darken underarms are caused by a medical condition, your doctor may prescribe medication to treat the underlying condition. For example, if your darken underarms are caused by diabetes, your doctor may prescribe medication to control your blood sugar levels.

Avoid shaving: Shaving can cause ingrown hair, try waxing or using hair removal cream. Waxing and hair removal creams remove hair without removing the top layer of skin, which can help prevent skin irritation and darkening.

Avoid tight clothing: Wearing tight clothing can trap sweat and bacteria on the skin, which can cause the underarms to darken. Wear loose-fitting clothing that allows air to circulate.

Keep the area clean: Keeping the area under the arms clean can help prevent darkening underarms. Wash the area regularly with soap and water.

Use natural products: Try using natural products such as coconut oil or baking soda as a natural deodorant. These products are less likely to cause skin irritation and darkening.


Darkened underarms are a common cosmetic concern that can be caused by various factors such as shaving, excessive sweating, and the use of certain products.

It is important to note that while darkening underarms may be a cosmetic concern, they are not usually serious medical conditions. However, if you are concerned about your darkened underarms or if they are accompanied by other symptoms, it is important to consult your doctor.

With the right treatment and prevention methods, you can improve the appearance of your underarms and feel more confident in your own skin.
