"I was surprised how small the bottle was when it arrived, but you only need to use a little bit. I've been on accutane 3 times so my skin doesn't break out as much as it used to, but since using Glytone Step 3 facial lotion (daytime) and exfoliating lotion (at night) I rarely break out anymore! It did make my skin peel when I first starting using it. I started with the Step 3 because I was using a lotion from my Dr.'s office which was a 10% glycolic acid. I'm not sure if it's reducing wrinkles but the texture of my skin looks and feels great."
