I often have new patients saying they can’t use retinols as they are too sensitive. It’s usually because they have purchased from somewhere without accompanying advice . The golden rule with any retinol is start once a week for two weeks then twice a week . Start with a low percentage and titrate up . Never apply more often than once every 3 days as this is how long effects take to show on the skins surface . If you are using a daily retinol without any problems then it’s not a very good one .
