This is my personal tretinoin routine for my sensitive and dry skin! I used to use Tretinoin around 5 days a week, but after a barrier freak out I’ve dialed it back to max 2x a week and using skinbetters alpharet overnight cream on the other nights in conjunction with barrier repairing only nights. Each section has products I rotate with in the routine, it just depends on how my skin feels is the one I reach for that night.
