Why Do Dark Armpits Develop?

Rather than having one simple cause, several factors can lead to dark underarms at varying levels of seriousness. The issue often occurs because of improper shaving, which leads to skin irritation and the development of dark skin.

Some commercial deodorants have allergens that can similarly irritate the skin, and this is also true of other items like shaving cream. While some products irritate, not using exfoliants can also cause this condition by allowing the pores to get clogged. This can augment the hyperpigmentation process, leading to dark skin.

There are also medical causes of dark underarms, very commonly a skin pigmentation disorder called acanthosis nigricans[2] that can lead to thick skin with dark areas. This is a cause for concern because it may be a sign of an underlying condition like diabetes or hormonal imbalance.

Hormonal issues can lead to melasma, a skin pigmentation often caused by an excess of estrogen and progesterone. This is an issue that is most common during pregnancy. However, don’t discount that your dark underarms may be a side effect of a medication you’re taking, particularly if it’s insulin or something that affects the balance of hormones. If you switch pills, it may get rid of dark armpits.
