As good as it can feel to get back outside in the summertime, there’s no denying that hot weather can irritate your skin (sweat, chafing, sunburns—you get the idea). One not-so-fun result of a day in the sun? Heat rash, also called miliaria or prickly heat, a condition caused by blocked sweat ducts, Victoria Billero, MD, a dermatologist at Tufts Medical Center in Boston, tells SELF.
While heat rash can happen anywhere on your body, it’s most common on your back, Dr. Billero says. You may notice small, sometimes fluid-filled bumps that appear pink and red on lighter skin tones or purple and gray on deeper ones. The rash might feel itchy, stingy, and just…uncomfortable.
But you don’t have to wait for it to go away on its own. We asked dermatologists how to find the best heat rash treatments. The products below will help prevent and soothe prickly heat, so you can get back to the pool, the beach, the court, or wherever else your summer takes you.
