Dark underarms can be caused by several factors, and while it's usually not a serious medical issue, it can be frustrating. Here's a breakdown:
Common Causes
1. Shaving – Irritates the skin and causes pigmentation over time.
2. Friction – Tight clothes can cause rubbing and darken the area.
3. Deodorants/antiperspirants – Some contain harsh chemicals that can lead to skin darkening.
4. Acanthosis nigricans – A condition linked to insulin resistance, obesity, or hormonal disorders.
5. Dead skin buildup – Lack of exfoliation can lead to darker skin.
6. Hyperpigmentation – Skin’s natural response to irritation or inflammation.
There are med and other treatment available.
