Undera Under-Breast Barrier Cream
The barrier made to sit under your bra.
Told it's fungal, but it keeps coming back? Your bra traps heat and sweat where skin rests on skin. Undera dries to a powder feel between skin and bra, with no grease.
🌿 Helps the fold feel dry under your bra, not damp
👚 No greasy film or diaper-cream mess on your bra
🛡️ Skin glides instead of rubbing every time you move
⏱️ One thin layer after your shower, then get dressed

Will it sting?
Undera is made for tender, irritated skin. It's fragrance-free. Most women feel cool relief, not a burn. If your skin is cracked or weeping, try a small spot first and give it a day.
Cream on. Powder feel. Nothing greasy under your bra.
Undera goes on like a light cream, so it spreads easily into the fold. Then it sets. Silica and tapioca starch dry it to a soft, powder-like feel. 15% zinc oxide leaves a thin layer between skin that touches.
So skin glides instead of rubs, and there's no wet, greasy film under your bra.

🌿 Calms the burning and itching on contact
It goes on smooth and cool, so that hot, raw feeling settles and you can stop thinking about it.
💧 Keeps the fold dry through heat and long days
Silica and tapioca starch soak up sweat as it happens, so a hot afternoon or a morning in the garden doesn't undo your day.
👙 Dries clear, with no marks on your bra
No greasy paste or chalky powder, just a light layer that dries in seconds and stays on your skin, not your clothes.
⏱️ One thin layer replaces your whole routine
Smooth it on after your shower and skip the powder, the paste, and the liners.
Real women. Real Sweat. Real Heat
I have somewhat sensitive skin, and there are areas that need more than just a regular moisturizer, especially under the breasts where moisture tends to build up. I decided to try this cream, and after using it several times, I can say it has been really helpful. It helped reduce the irritation and redness I had, and now my skin feels much softer. One thing I didn't care for too much is that it takes a little while to absorb, and you can feel the product on your skin for a bit. Good for sensitive skin and rednessLesi M.
This stuff is amazing for heat rash. I was suffering after having been outside for an entire day in super hot and humid weather…developed a heat rash in my pits and under boob areas (sorry if that’s tmi but this stuff is a miracle!). In just two days it was so much better! This stuff is great cream!inda A. Lolie
This is the worst image i have with my under boob rashes. A few seconds after I applied this cream, I instantly feel relief! I never knew what I was suffering from but now I know it is intertrigo. The red and purple itchy rash under my tummy folds have already changed color to a white, and under my breasts, the rash has practically disappeared. There was no burning. There was no pain, I highly recommend this to anybody suffering with this problem. I love yhis stuff! There was no burning.Rita Q.
This worked wonders on me. Soft, smooth, easy to apply & not sticky. Saw positive results overnight. No more severe itching, redness & soreness. Applied under the breasts, by stomach fold & by groin; no irritation. Will be making this as an ‘as needed’ application; & especially for the summer. So glad I found this. No scent.
