Underboob Rash

When we talk about sweet spots, we’re not just talkin’ vaginas and vulvas. We’re talking about all intimate skin - every fold, curve and contour. And that includes boobies! When it comes to breasts, one of the biggest skin concerns is a rash under the breasts.

What causes a rash under breasts?

Heat plus moisture plus friction usually equals underboob rash. So if you live in a humid climate, spend a lot of time in a sweaty sports bra, or have large breasts that tend to sweat and chafe, you’re more likely to end up with an underboob rash. But not all underboob rashes are the same! Here are some of the most common types.

Heat Rash

Heat rash is the common name for miliaria, and it’s what happens when your sweat glands get clogged, leaving sweat trapped under the skin and leaving you with an itchy rash. If you’ve got heat rash under your breasts, the best thing to do is cool off! You can use a gentle soothing wipe under each of the girls to help calm things down, and the rash will usually go away on its own in a few days.

Intertrigo

Sometimes called candida intertrigo, this is a red, itchy, sometimes painful rash caused by an overgrowth of bacteria, fungus, or yeast. It tends to show up in warm, moist environments - like the skin folds under your breasts, under your arms, between butt cheeks, and the vulvar/groin area. If you think you may have intertrigo, be sure to consult with your healthcare provider for proper diagnosis and treatment.

How can I prevent rashes under my breasts?

1. Cleanse Daily

Keeping the skin under your breasts clean helps minimize your risk for developing underboob rash. Try a gentle, soap-free cleanser like this one to support healthy, balanced levels of bacteria and fungi without irritating skin. No time for a shower? Swipe this deodorizing gel under the girls to quickly cleanse and help reduce sweat-producing enzymes.

2. Keep it Dry

After a shower or after a workout, be sure to thoroughly dry the underboob area. Pat dry with a clean towel or give it a blast with your hair dryer if you’re feeling frisky! And always, always change out of wet clothes ASAP.

3. Go Natural

Opt for bras made of natural, breathable fabric like cotton instead of synthetics that tend to trap moisture.

Need relief?

If you’ve got an itchy underboob area, a barrier cream like Rescue Balm can help relieve dry, irritated skin while helping to protect the skin from further chafing.
