Loves this!
Sampled

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.

My favorite face cream yet!
Sampled

OMG I love this product and plan to buy a big bottle! It goes on so smooth, and instantly makes my face look brighter. I can apply it as many times a day as I want and I can sleep in it. I love the consistency. I can see a difference just using up the small sample.
