armpits

While chemicals and shaving are the main causes for dark underarms, even friction caused by excessive sweating and tight clothes can darken armpits it’s because tight clothes rub against sweaty skin to lead to friction and consequent darkening of the skin. Lack of hygiene can lead to infections, itching and scratching which in turn leads to rough, scaly and dark skin. Even pollution, buildup of skin cells, type-2 diabetes, genetic predispositions and hyper pigmentation can lead to dark armpits
