Hi, I'm 27 and have had a very stressful few years. As a result, I have a static fine line across my forehead that won't go away. I've read that retinol is good to reduce fine lines but I worry that I'm too young to start using it and/or that it may actually damage my skin. Does anyone have any advice on what I can start using to reduce it, prevent it getting worse and avoid further fine lines?
