Oh forgot to mention. I use the Retin A on my chest to get rid of brown spots. use a bit on my hands as well. no redness there.
I have been using Retin A .5 for about 3 weeks, in teh redness phase, but not terrible, will continue - but I noticed about ten skin tags - some tiny some larger on my chest and neck. does Retin A cause these? nothing else have...
