This serum works well. It really reduced my dark sport and my wrinkles. It feels fresh and it is easy to apply. The only down side is its small quantity for the price.

I haven't seen a better product. Although the product is a bit expensive, it really repairs my skin and my wrinkles are gone! I am in my late 20s and I had crow's feet and after 3 weeks of spot application of this product, I don't see the wrinkles on my face anymore. This is truly a great product offered by Biotherm since Pure-fect skin line up.

I've tried many products, just this one really works

It feels good on my skin. I have dry skin and this product goes on smoothly and makes my skin feel velvety. It is a good anti-aging product. Using it in conjunction with a night cream seems to create softer skin. The product is great for firming the skin and lessoning wrinkles. The texture of the serum feels good going on

This is one of the best products I have used to improve my skin condition, and I can see the difference.
