Many people suffer from dark spots on the skin in the underarm area. These spots can be caused by biological factors like naturally dark hair follicles and fungal infections, as well as certain activities such as shaving or using deodorants with alcohol or aluminum. Even the build up of microscopic dead skin cells can cause discoloration. There are a number of ways you can remove dark spots from your underarms depending on your specific needs.
Combat fungal infections with creams or pills prescribed by your dermatologist. If you suffer from hyperkeratosis (when brown skin thickens under the armpits due to an excessive buildup of keratin in the skin), your dermatologist can recommend topical creams that contain salicylic acid, alpha-hydroxy acid with lactic or glycolic acid, urea, tretinoin or hydroquinone (2-4%).
Treat a medical condition called Acanthosis Nigricans with prescription medication. This condition is typical in overweight people and can be treated using Retin-A, 20% urea, alpha hydroxy acids and salicylic acid. Monitoring your insulin levels to keep them in control can also help resolve this condition.
Combine 1 teaspoon of lime juice, 1 teaspoon of cucumber juice and a pinch of turmeric powder in a bowl. Using a cotton washcloth, spread the mixture on your dark spots and let it penetrate for 15 minutes. Rinse and repeat daily to remove dark spots.
