How to stop boob sweat rash?

There are a ton of really effective products that can help prevent boob sweat rashes.

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