What are the causes of dark underarms?

Dark spots under your arms can be a result of a medical condition called acanthosis nigricans. It can be caused by various other reasons such as:

1. Shaving:

Shaving removes the hair visible to us, from the surface, and the hair follicles just below the skin are the reason for these dark spots. Too much shaving leads to skin darkening and even hardens the shaved area. While waxing removes hair right from the root. It leaves skin soft and even removes dead skin from the surface. Waxing is a little clumsy but far better than shaving in this regard. If the discoloration in your armpits is due to shaving, switch to waxing now.

2. Excess use of deodorants:

In spite of the fact that deodorants are a life saviour for fighting against bad body odour their excess use leads to darkening of the underarms. Alcohol based anti perspirants and deodorants are harmful to the skin. The chemicals present in them are responsible for the blackness of the armpits. Avoid applying these harsh and harmful chemicals directly on your skin.

3. Accumulation of dead skin cells:

Our body sheds dead skin cells regularly. The shedding gradually reduces with age. That’s why a baby has soft skin and we don’t. The shedding is by itself in some people while in some other the skin do not flake away which leads to its accumulation. The accumulated dead skin cells makes the skin appear dull and dark. There is a need of properly cleaning and exfoliating the skin so that the dead skin is removed. Most of the people ignore the underarms while cleaning which leads to dead skin accumulation and the so the dark spots. So, exfoliate.

4. Regular use of hair removal cream:

Excess use of hair removal cream leads to darkening of the underarms due to the chemicals present in them. It removes hair only superficially and not from their root. So, stop using these creams if they are the reason of your dark underarms.

5. Wearing tightly fitted clothes:

Wearing tightly fitted clothes leads to rubbing of the skin with the fabric. The friction between the cloth and the sensitive areas like underarms leads to their darkening. To avoid the darkening caused due to this reason, wear loosely fitted clothes specially during summer.

6. Acanthosis Nigricans: [1]

Acanthosis Nigricans is a medical condition in which brown to black patches develop around the body folds. It is hyper-pigmentation of the skin and is usually caused in folds of the neck, armpits, etc. It may be genetically inherited or may be caused by obesity also. The discoloration caused due to this reason can be kept in check by consulting a doctor and taking the necessary precautions.
