Not what it claims to be.
This product comes in a very small tube,  the brush does not reach the serum at the bottom so you loose that amount because it is hard to collect it on the tiny brush by tipping bottle sideways.  I used the product as directed and within two weeks absolutely no results and bottle was done.  Company apologizes but will do nothing to assist you with a guarantee refund or the purchase of a second bottle to see if it just takes another 2 weeks to begin seeing results.  All in alI, I felt I had thrown my money down the drain.  Buyer beware.
