Save us, oh great one !! Again, this is Iodine support forum. It seems to me you are like Trapper, always absorbed in others' business. Thats a commie way to be, instead of focusing on your own matters, you come to disrupt an Iodine forum.
If you truly want to warn people about retinol, there are other forums on this site where your message would be seen by many many more people. Thus, its clear your intent was not to warn anyone, but to disrupt this forum. Plain and simple. Now, please, go mind your own business, ok ?
