What Is Actually Going On In Your Skin Folds
Skin folds trap heat, moisture, and friction in one small area. That combination creates ideal conditions for yeast (commonly a type called Candida) and bacteria to multiply on the skin's surface.
The redness, burning, odor, and cracking aren't just "sweat irritation." They're signs of that overgrowth at work.
It can happen in any skin fold, underarms, under the breasts, the groin, stomach folds, even between fingers or toes, in people of any body size or fitness level. Deeper or tighter folds simply trap more heat and moisture, which is why it tends to show up there first.
