I had a sea weed wrap about this time last year when I was in the middle of a major flare up of P/PA.
I can't say it did anything for my skin because it was in such a state but I did lose 9 inches (you get measured before and after) the girl said she had never known anyone lose from their elbows!!!!! Shows how much inflammation I had in my body, I guess.
Once the srap is on you body gets very hot, only mine seemed to be twice as hot because of the P, it was like someone puring very hot water over my body. It does die down after a few minutes. I felt really good after it for the rest of the day and had a great sleep that night.
I might consider it again now that my skin is on the mend.
