Nothing ruins a day quite like thigh chafing. You probably barley notice it at first, that building stinging. It’s a hot day; a day for shorts or a skirt, and you probably aren’t even going to walk that far.

And then it starts—a subtle discomfort that feels like you could relieve it easily with a well-timed breeze, building into a pain severe enough to make you walk bow-legged.

From wearing a skirt in the summer to ill-fitting clothing to a common side-effect of pregnancy, you can encounter a chafing rash countless ways. Maybe, like me at 18, you decided to go on a water ride in the June heat of Universal Studios, and by the end of the day swear to never wear another pair of jean shorts for the rest of your life.

No matter how you first encountered it, thigh chafing can be nearly debilitating. But thankfully, it’s easy to prevent.

Recommended by both Dr. Henry and Dr. Kung, Body Glide is a sweat– and water-resistant balm meant to prevent chafing, irritation, and raw skin. This child-safe product glides on easily to create an invisible barrier between your skin and the rest of the world.

Derived from plant waxes, Body Glide’s formula allows sweat to escape while keeping the skin itself dry and protected. It can be easily applied to any area of the skin that experiences chafing rash and the glide-on applicator keeps your hands clean.

The formula is fragrance-free and vegan, and goes on dry and grease-free. Body Glide is great for even the toughest conditions, and has been partnered with the USA Triathlon since 2001.
