amazing [SEP] while this is outrageously priced it really does seem to work i have tried many serums but really never found anything significant with any of them this works my faces looks like it glows even in this dry and bitter cold weather i would never pay this much for this but it does last a tiny drop is all that is needed and it is non irritating even with my sensitive skin the primrose oil probably helps a lot there is barely a scent too my skin looks firmer plumper and just more radiant
