I was very satisfied, applying every night I saw great improvement in deep & expression wrinkles quite soon (4-5 weeks).

The best on the market by far and lasts forever! Over 7-8 months with daily use! It requires a minimal amount and gets the job done immediately! If you put even a little bit more, it will leave a sticky residue, the residue will dry and create a film like a patch! For better results, use it during derma roller or after a hot bath!!
