This serum is wonderful! I did not experience dramatic anti aging benefits from it which is not surprising as I am still in my 20s, but it did absolute wonders to calm my skin during tretinoin therapy. Honestly, it is the only thing that prevented significant irritation and flaking during retinol therapy. When I was using it, my skin just looked better, calmer, and redness was reduced. I just wish it wasn't so expensive. In the past few years, the price has gone up significantly!
