Not bad. Just wish they listed retinol %
I bought this sample based on Amazon reviews for the full size.  It is not a bad product at all. Gel glides on smooth and evenly. Dries quickly and is not tacky, my issue is, I am not certain it contains the amount of retinol I am looking for. Over time I will achieve the same result. Since I am uncertain the % of retinol, I am going with a different product to try.  Used for almost 2 weeks which really isn't enough time for any significant results. Used in the evenings before nighttime moisturizer.
