I was using skin+me and they prescribed Tretinoin which I think worked ok but didn't have the effect that everyone says it will (used religiouslyfor 6+ months). I've found the dr Dennis gross peel pads make much more of a difference for brightness even if just using once a week.
I have had to stop using skin+me as I've had an eczema flare up right next to my eye. I use a lot of k-beauty products which I love and saw that skin1004 have started doing a retinol serum. Is it worth it or just a waste of time? I'm late 30s and would love to avoid wrinkles as best I can!
