I love this retinol 0.3! I am finishing this bottle then going up to the .5. It has been life changing, I've been on it for 2 month's and my skin looks so much better. I started out once a week, and it did dry me out slightly..But after about a month of once a week my skin did nothing but glow after I used it. So then I started doing it every 3 nights and I've never looked back. Amazing how well your skin adjusts to the retinol when introduced slowly. I was scared to try it because at times I struggle with Perioral Dermititis, but so far this retinol has not irritated my skin and I have been dermititis free. My wrinkles are reduced and my skin is smooth as a babies butt.
