Dark underarms can be an embarrassing and uncomfortable problem. It is caused by a variety of factors, including hyperpigmentation, and can be difficult to treat. This article provides an overview of the causes, prevention, and treatment options for dark underarms.

Causes of Dark Underarms

Dark underarms can be caused by several factors, including:

  • Hyperpigmentation: This is a common cause of dark underarms and occurs when the skin produces excess melanin, the pigment responsible for skin color.
  • Shaving: Shaving can cause skin irritation and darkening, especially if the skin is sensitive or prone to ingrown hairs.
  • Deodorants and antiperspirants: Certain deodorants and antiperspirants can cause skin irritation and darkening, especially if they contain harsh chemicals or fragrances.


To prevent dark underarms, it is important to:

  • Exfoliate regularly: Exfoliating the skin regularly can help remove dead skin cells and prevent the buildup of dark patches.
  • Choose gentle, unscented deodorants: Avoid deodorants and antiperspirants that contain harsh chemicals or fragrances, and opt for gentler, unscented options instead.
  • Avoid shaving or waxing: If possible, avoid shaving or waxing the underarms, as these can cause skin irritation and darkening. If you must shave, use a gentle, moisturizing shaving cream and a sharp, clean razor.


Treatment for dark underarms can vary depending on the underlying cause. Some options include:

  • Skin lightening creams: Over-the-counter skin lightening creams can help reduce the appearance of dark underarms by lightening the skin. It is important to choose creams that contain safe and effective ingredients, such as kojic acid or glycolic acid, and to follow the instructions carefully.
  • Laser treatment: Laser treatment can help reduce the appearance of dark underarms by removing the excess melanin that causes hyperpigmentation. This treatment is typically performed by a dermatologist and may require several sessions to achieve the desired results.


Dark underarms can bean embarrassing and uncomfortable problem, but with the right treatment, it can be improved. By understanding the causes and taking preventive measures, such as exfoliating regularly and choosing gentle, unscented deodorants, you can reduce your risk of developing dark underarms. If necessary, skin lightening creams and laser treatment can also be effective in treating dark underarms. If you have concerns about dark underarms, it is important to discuss your options with a healthcare professional to determine the best course of treatment for you.
