I echo what Gary has said. I have never heard of cornstarch being useful for our radiated skin. I was also warned not to use anything on the skin before treatment. My skin around the neck was severely burnt but that healed within three weeks post treatment. No more blood, no more pain but two years now, people still wonder what has happened to my skin when they are close to me. It looks like a severe sunburn that does not go away. Before healing, you feel very itchy. Gary is right that you should never scratch!
