I've been using retin-a for years ( tretinoin) I love it. It works wonders- I take breaks from it during the summer just because I'm outside more. I've been using the micro for the last few years it's great. I think it works better than the cream. I had the peeling and redness when I started on the micro but it went away. I had read a review where someone was using it on their neck, why I never thought of this I don't know but I tried it and I used it on my chest as well- there

I grew up in Florida going to the beach and using the tanning beds back in the 80's- I never heard anything about sunscreen. In my early 20's I got my first AK. The dermatologist froze it off and told me since I was blonde and fair skinned to be careful and to watch my face because that's where the skin cancer would show up first. Since it's always exposed to sun. I stopped lying out in the sun and started wearing sunscreen but the damage had already been done, over the years
