1) Shave At Night
If you’re going to shave, I recommend shaving at night. Shaving ANY part of your body at night gives your skin time to heal and recover overnight before you expose it to products like deodorant. If you have melanin rich skin use a shaving oil it will help soften the hair and create a barrier from the razor. This is a much better option than a shave cream or a soap. After shaving use an aloe gel to calm the skin overnight. Taking these steps to help prevent inflammation and adopting new habits will help save you from dark pigmentation issues in the long term.
2) Look for Irritating Ingredients in Your Deodorants
Don’t use deodorants with irritating ingredients like baking soda, alcohol, or high levels of fragrance. If you use anti–perspirants the aluminum can be a major irritant for sensitive skins and dermatologist will agree that you need to look for skin calming odor protection.
3) Stop Wearing Tight Clothing
The friction and chafing from clothing can also irritate the underarms and cause PIH. Wear light and breathable fabrics (such as cotton, linen, bamboo) or loose fitting items
