For many people, dark underarms can be a source of embarrassment. Darker underarm skin can keep some people from dressing in sleeveless tops, wearing bathing suits in public, and participating in sports.Like skin blemishes and discoloration on other parts of the body, dark underarms can result in a lack of confidence and self-esteem.
There are various potential causes for armpits becoming darker including:
- deodorants and antiperspirants (chemical irritants)
- shaving (irritation and abrasion)
- dead skin cell accumulation (lack of exfoliation)
- friction (tight clothes)
- smoker’s melanosis (hyperpigmentation caused by smoking)
- hyperpigmentation (increased melanin)
- acanthosis nigricans (often a sign of diabetes, obesity, or abnormal hormone levels)
- erythrasma (bacterial infection)
- melasma (dark patches on skin)
- Addison’s disease (damaged adrenal gland)
The first response to the “how to lighten armpits” question is to address some of the basic causes:
- Change your brand of deodorant/antiperspirant. Some people switch to a natural alternative such as baking soda or apple cider vinegar. Some people stop using a deodorant altogether.
- Stop shaving. Some people select waxing or laser hair removal instead.
- Exfoliate. Many people use a body scrub or a facial exfoliator two to three times a week.
- Wear loose-fitting clothes.
- Stop smoking.
