Age, like the force of gravity, tends to pull features down. But this is not inevitable, and you can maintain the firmness of the tissues.
By smoothing: apply your serum or your firming cream by rubbing from the base of the neck, then going up little by little along with the jawbones and towards the cheekbones. Also, perform petite circular massages.

Pinching: grab the flesh between the thumb and index finger to pinch, always following the same path.

By toning: contract, at a rapid pace, the neck muscles. You should see the tendons and muscles taking shape.
