Those mineral wraps are similar to ones that I had during my kid years. My family and I usually go to the Black Sea and stay at one of the resorts on the sea coast and take the sunbathing and swimming in the sea daily for maximum 2 weeks. During this time we would go to another smaller city by the coast and take mud baths in a mud lake, and the mud is always black/indigo. The mud will dry of course but the benefits I've seen is that it could remove the redness from the burnt skin, as well other health benefits.
