5. Wear Sunscreen โ€“ Yes, You Read That Right

Ideally, you should be wearing sunscreen on any exposed portion of your body when you are out in the sunshine. If youโ€™re wearing a tank top or your bikini, that means slathering up your armpits in addition to the rest of your body. This will help prevent sunburn in your armpits, but it can also reduce the risk of pigmentation changes and skin cancer. Choose SPF 50 and reapply every couple of hours.
