BD1791 It will help your skin to recover. It will help to prevent it? I don't know. Test is and tell us.
At another forum I found this information:
I've had luck with aveno lotion rubbed under the waistband daily, then vasoline applied on the inside of the thighs where the edge of the belt rubs, that has to be reapplied more like 2x a day.
I also found it's key to put whatever you're using on right from the beginning, and not wait until the chafing is becoming an issue, because it's a lot easier to stop it from happening in the first place, then fix it after you rub the skin down while still wearing the belt.
And:
One problem if you use solid coconut oil is summer weather causes it to melt.. Even in a car with the AC on.... I switched to Shea Butter, with some Coconut Oil and Almond Oil. After mixing (DM me for the directions) it does not melt until over 100 F.
