I didn't know that a beauty product keeps your skin supple. 
I've always thought it was more to with genetics and what we eat and avoiding cigs.
I've heard Josie M say on air that Argan Oil is all you need and it will keep your skin plump and firm. But, I've never heard a Qvc host say it because it's not true and they'd get in trouble.
So whether it's Dr Denese pads or the Josie's Argan Oil I'd go with the least expensive one because it's all a bunch of b.s.
One should keep their skin moisturized and drink plenty of water and stay away from the damaging affects of sugar, sun and cigs.
