DIY Bye-Bye to Dark Underarms.
Looking for ways to lighten dark underarms naturally? Mix baking soda, lemon and water into a paste, apply to underarms, leave on for 20 minutes and rinse. Simply switching from shaving to waxing can also help avoid hyper-pigmentation caused by irritation (go a professional, especially if you have hair growing in different directions/curly hair). If you have sensitive skin, try mixing coconut oil with lemon instead of baking soda - and if you have a shaving emergency coconut oil is a good substitute for shaving cream. You'll see smoother, softer skin - and it can help with discoloration (without some of the toxic ingredients found in shaving creams and gels). Exfoliate the underarms once a week BEFORE shaving, (the LuvScrub Mesh Body Exfoliator is great) to remove dead skin and any buildup from deodorant. Dark underarms can be a sign of a condition known as acanthosis nigricans, which usually occurs in combination with insulin resistance, obesity, hormonal imbalances, certain drugs and even cancer. If the problem persists or worsens after trying the above remedies, you may want to consult your health-care provider to make sure an underlying condition isn't the cause.
