Natural Remedies for Underarm Whitening

Having dark underarms can be an embarrassing and confidence-lowering issue for many people. The skin under the arms is delicate and prone to pigmentation due to friction, shaving, dead skin cells build up, use of chemical laden deodorants and antiperspirants, hormonal changes etc. Thankfully there are some simple, natural ways to lighten the dark underarms and get back your confidence.

Causes of Dark Underarms

Here are some of the common causes behind dark underarms:

  • Shaving: Using razors irritates the thin underarm skin which can cause pigmentation and darkening. The irritation and inflammation leads to excess melanin production.
  • Deodorants & Antiperspirants: The harmful chemicals like alcohol, fragrances etc in deodorants/antiperspirants can react with the underarm skin and cause darkening over time. The aluminum salts in antiperspirants also accentuate the problem.
  • Dead Skin Cell Buildup: Accumulation of dead skin cells can block pores and lead to dark elbows and knees. This can happen in underarms too.
  • Hormonal Changes: Hormonal fluctuations during pregnancy, menstruation, menopause etc can trigger excess melanin production leading to pigmentation.
  • Excess Sweating and Friction: Excess sweating and moisture in folds like underarms can cause friction and darkening. The constant friction also irritates the skin.
  • Obesity: In some overweight people, the underarm skin can become darker due to constant friction between arms and body.
  • Medical Conditions: Certain medical conditions like acanthosis nigricans can also cause pigmentation in body folds including underarms.
  • Genetics: Some people are just genetically predisposed to have darker underarms.
