Seems a little expensive. Nice formula but not totally sold on the product.

I am relatively new to wrinkle products, but I used the entire tube and went ahead and bought an actual bottle. I use this morning and night and it makes my skin look smoother and feel softer!

Great really works
Sampled

I sampled this and it was awesome. Goes on light, immediately makes your skin look more toned. It did make my eyes burn a little when I layered too much one once, but if you use a thin layer it feels good.
After several days I felt like my fine lines really disappeared. I like that this is a retin-a free product that actually works. Will likely be buying this soon.
