I'll be the first to admit it, I have tried everything on the market for my skin. I tried the sample of this serum, and it soaked right in and gave my skin a nice glow. I was tempted to see more results, so I ordered the full size bottle. My skin is smoother, softer, and the wrinkles are fading! I have oily skin, and this just sinks right in and leaves no residue. The ingredients are great, and I know my skin is gradually improving. I will definitly repurchase this one!
