Armpits & Underarms
Your armpits might be the last place you thought of applying sunscreen to. However, they should receive some extra care, because any skin that isn’t normally exposed to the sun is even more susceptible to burning, including your pits.
Our recommendation is to apply some SPF 30 + on your armpits before you use any deodorant or antiperspirant. This way, you’ll be giving your skin enough time to absorb the sunscreen.
You’d still have to apply it constantly during the day, but at least you will be sure that area of your body will never get irritated and itchy from a sunburn.
