I have been using this night cream for about three weeks. I also use Dr. Graf's Retinol Serum, a product I like and from which I see results. For reference, my skin is slightly oily.
After about two and a half weeks of using this cream, I began developing large cyst like pimples underneath the skin. Since it is the only product that has been added to my regular regime, I think it is the culprit.
I should have had a clue because the cream feels very good but does not absorb at all; just sits on top of your face. I found that every day my skin became increasingly greasy by mid-day.
I started using these two products from Dr. Graf in a quest to reduce the cost of my skin care, although not at the risk of causing skin issues. I will continue to use the Retinol serum but have now started using Erno Laszlo's Phelityl Night Cream for normal skin. I will post a review after a month or so. So far, so good.
