Review (5/5): Good stuff!!!
I'm 46 and I started using this serum along with vitamin c serum right after. Somebody had told me to try these two items together and I've been using religiously for 6 weeks. Somebody said something about the cost but since you really only need a drop or two it lasts for a long time.
I'm very happy with the way my skin looks now. I totally recommend this product!!
