You mean retinol? I've just read a lot of good things about it, but still, the side effects remain and I'm not sure I can handle them on my own at home. I speak hypothetically, because I rarely do experiments with my skin, if something happens, there is no one to turn to, 😃 skin doctors are busy with hyaluronic injections and botox and have no time for real diseases and skin damage.
Thanks for the info!
