Cutout dresses, swimsuits, tattoos — the underboob is having a moment. There's a lot of focus on that area of the body - but what about the part people aren't talking about? The sweat. The chafing. The underwire bra lines. Let's talk about all things underboob!


Although sweating anywhere on your body can be uncomfortable, underboob sweat can be particularly unpleasant. It is not because there is more sweating in that area. Instead, the underboob area (where the breasts meet the torso) tends to hold onto excess moisture because there is little air to evaporate the sweating. Underboob sweat is a common concern, especially for women with larger breasts.

How to avoid underboob sweat

You can avoid underboob sweat by wearing cotton or breathable/loose underwear. These clothing types help reduce perspiration and prevent moisture from being confined under the breast. Remember that changing the undergarment can make a difference but may not stop you from sweating. So, in addition to wearing breathable clothing, use deodorant under the breast to help prevent sweat, soak up moisture, and soothe the skin. Another tip is to use a cleanser, like our Gentle 2-N-1 Foaming Wash, that helps manage pH levels.

Underboob Chafing

On hot or humid days, sweating and chafing under the breasts is a very common experience, particularly during physical activity. The combination of moisture and friction is the main reason for underboob chafing, which is most likely to occur in the areas between and beneath the breasts due to excessive rubbing against the skin. Underboob chafing can become a significant and persistent problem for numerous women in an environment with poor ventilation, high temperatures, and sweat.

Those who are more likely to experience underboob chafing are athletes, overweight individuals, or individuals who wear ill-fitting bras. Wearing a bra for extended periods can be uncomfortable and irritating, particularly during physical activity when friction against the skin is more pronounced. The accumulation of moisture in this area can also promote the growth of bacteria and yeast, exacerbating discomfort and increasing the risk of infection. If left untreated, chafing can progress to a rash, requiring topical medications for relief.

How to prevent underboob chafing

Everyone knows how uncomfortable and embarrassing chafing can be. Skin rubbing can cause itching, burning, swelling – even bleeding and skin discoloration under the breasts and in other parts of the body. Our entire chafing and irritation collection is dedicated to helping everyone who deals with chafing get the comfort they deserve.

  • Balm - We recommend using our Kushae Protective Feminine Skin Balm with key ingredients that are "Mother Nature"-approved ingredients to deliver the cream that ends all chafing, sweat irritation, and rubbing burns:
    • Natural olive fruit oil (reduces friction and wicks away sweat)
    • Anti-inflammatory Goldenseal (heals skin)
    • Anti-bacterial Calendula (soothes and protects)
  • Clothing - is a massive cause of underboob chafing, so properly fitting clothing is necessary to prevent it.
    • Avoid tight sports bras, and look for those with moisture-wicking fabrics.
    • Wear cotton sports bras because they can absorb sweat and prevent moisture from staying on the skin.
    • Consider one of the new breeds of bras that are supportive but don't have an underwire.
    • Get fitted for a bra that truly fits and distributes weight.
  • Cleanliness - Staying clean and thoroughly drying yourself is another way to prevent underboob chafing. You can use a brush or loofah for weekly skin exfoliation to remove dead skin cells. Daily, wash off sweat with non-scented soaps and pat the area dry to remove all moisture.

The underboob area can experience many discomforts, such as excessive sweating and chafing, which can be painful and irritating. We provided ways to alleviate the aches so you do not feel uncomfortable. Check out our chafing and irritation collection.
