What Causes Dark Underarms
Underarm hyperpigmentation or acanthosis nigricans, is a common skin condition characterized by areas of dark pigmented, thick skin. Although many of us may suffer from dark underarms, the solution to the problem might be a lot less complicated than you may think.
The repetitive irritation and friction caused by shaving can produce more melanin. This process promotes the development of greyish-brown or black pigmentation in the underarm area. Applying deodorant right after shaving actually promotes more irritation. This irritation causes the skin to get thicker and thicker to protect itself, also causing color changes to the affected area.
How to Get Rid of Darkness
A quick and simple tip to avoid underarm darkness is to shave at night. This way, by the time you apply your deodorant in the morning your underarms have had time to calm down and aren’t inflamed anymore. It sounds simple, but it works!
