I have suffered with terrible prickly heat for many years. I came across this and my condition improved dramatically. Along with the SPF 15 which I followed this up with I had a lovely long lasting tan. It didn't stop my prickly heat completely but it was definitely more manageable.
I bought this for my wife after we bought one in florida the other year and she loves it, gives great protection and the anti aging portion of it seems to work, i wouldnt hesitate to recommend this product to anybody she loves it.
