Review (5/5): A truly strong retinol product without a prescription!
I really love this retinol serum. At a level of 2.5% retinol it has a high level of retinol. I would recommend starting off sparingly, 1 to 2 times per week at night only, until your skin acclimates to it. I use it nightly now and I've noticed my wrinkles have been put on pause! Also be sure to wear suncreen everyday while using as your skin will be more susceptible to the suns rays.
