Has anyone heard of or used a product called Heliocare? I was told about it by a friend who gives it to her children. She says that they don't have to use sunscreen after taking it for a couple of months. They have a pool and use it regularly and they don't get sunburned. I did a little research and it is a natural fern extract that has been used in the UK for over 20 years with no known side effects. I have decided to try it, but wanted feedback from anyone who is familiar with it.
