The IS Clinical products were introduced to me by my skin care specialist.  Do your skin a favor and get this.  Is it expensive? Yes but worth every drop.  Think how much you will save in getting all those drugstore serums that don't work.  Will it totally erase wrinkles?  No, of course not......BUT it WILL definitely make your skin brighter & healthier looking and it certainly does lessen the look of wrinkles.
