Boob Sweat 101: How to Prevent + Stop Boob Sweat

Boob sweat comes for most of us. If you've ever found yourself in a sticky situation, you're definitely not alone. Though moderate boob sweat can be perfectly normal, it's not always comfortable. The good news? There are plenty of methods to keep you feeling fresh and dry all day long. 

What is Boob Sweat?

Boob sweat is the perspiration that collects inside your bra, between, and around your breasts. It's usually caused by the normal sweat culprits, like excessive heat and exercise. However, changes in the hormones estrogen and progesterone can also be the cause.

Most of the time, a little extra sweat around your breasts is a totally normal body function. That said, too much dampness can lead to skin irritation and discomfort. Not to mention, boob sweat can also ruin a perfectly good outfit. Luckily, we have some solutions.

Bra Hacks to Beat the Heat

One way to combat boob sweat is by picking the right bra material. If you’re looking for something that’s breathable and keeps you cool, you’ll want a natural material like cotton or tencel, or something super light like mesh. Breathable materials can help prevent sweat from forming.

If your goal is to find something that’s moisture-wicking, you’ll want a synthetic material like nylon or polyester. While synthetic materials are known to trap heat (which can sometimes make the problem worse), they're a better option if your primary goal is concealing sweat rather than preventing it. 

If your favorite bra is making you sweat but you're not quite ready to give it up, you can purchase a moisture-wicking bra liner, like this one by Belly Bandit. This liner creates an absorbent barrier between you and your bra to physically mop up any sweat before it bleeds through your top.

Wardrobe Tips for Reducing Breast Sweat

Sweat-busting can also happen at the wardrobe level. Loose, flowing tops made from lightweight fabrics like cotton or linen promote air circulation and help sweat evaporate faster. Wearing black clothing can make sweat less noticeable. 

Products to Prevent and Manage Boob Sweat

There are a ton of really effective products that can help combat boob sweat. MegaBabe’s Bust Dust is really wonderful - it’s a talc-free powder that absorbs sweat instantly, helping to keep your bra and top dry. Lume and Native have also recently come out with whole body deodorants, which are essentially deodorants that can be used anywhere — not just your pits. In a pinch, you can also just use the deodorant you already have on hand. 

These products are designed to dry up sweat, prevent new sweat from forming, and leave a nice scent. 

When to See a Dermatologist

For many, boob sweat is just a minor inconvenience. But if it disrupts your daily life or causes severe discomfort, it might be time to consult a dermatologist.

Excessive sweating might indicate hyperhidrosis, a condition where you sweat more than usual. A dermatologist can suggest stronger treatments, such as prescription-strength antiperspirants, to help manage the issue.
