I am not using the plexiderm. I find it hard to believe that any skin product marketed as saving, repairng, improving your skin doesn't have a sum screen in it. When I was finally able to read the small print telling me that plexiderm made my skin more sensitive to the sking, I tried it with putting my sunscreen on top but I don't like the feeling of stuff on my skin. One layer of lotions, etc, I will put up with but not two. Thereforee, I do not want any more sent and would like information as how to return the products, etc. I haven't communicated with the company as I have been involved in many medical tests, which hopefully are now complete.
