Prevage intensive serum retails at $270.. per 30 mls. It is one of the most intensive active serums containing idebenone. It will firm, intensely hydrate and remove unwanted dark blemishes. As $270 is a large outlay I have some deluxe sample sizes 5mls $30 worth at $15.00 each this should last you over a fortnight. The difference in the texture & quality of your skin will eventually lead you to a full purchase. It is an absolutely beautiful product. New unused. Trusted seller. I am offering free postage as I believe you will love this product. I have a few to sell.
