Quantity and Finesse
Initial use confirmed that the product does tighten skin, but the effect was not as dramatic advertised photos. It is likely that skin that is naturally firmer would not show as much change as damaged skin.  As reported, the application device does need a lot of priming for first use. It is also likely that as a person learns how much to apply and develops an optimal touch for each area that the product could serve its purpose very well.
