Why this stuff hasn't been publicized more is beyond me. This silicone-based powder gel is perfect for any area where you may have chafing, whether it be due to skin against skin or fabric against skin. It spreads easily and leaves a thin silicone coating that is like Teflon. As advertised, it's non-greasy and dries quickly. I liked this product so much that recommended it to my mom who has chafing from her masectomy prostetic bras (apparently, the prostetics hold heat a lot, causing lots of sweat and chafing).
In a totally different use, this powder gel also makes a great make up primer. Apparently, those high-end primers that cost five times as much are made of the same ingredients (namely, silicone). It allows for beautiful liquid foundation application!
For whatever use, don't be turned off of this great product just because it's made by Monistat. This stuff has nothing to do with yeast infections, though it is generally found in the "feminine products" aisle.
