yo, im almost 17 myself. i tried using retinol too and it gave me acne. dont use it. if you have bad skin already then you are either sick or really unhealthy. i used to cake my skin with products and had shitty skin, i now only use a cleanser every night, red light therapy before bed and occasionally a moisturizer and my skin got way better. just exercise, drink 1 gallon of water a day, and dont eat like shit and you will have good skin. alain delon in your pfp didnt use shit on his skin, neither did sean o pry or chico.
