Collagen makes up about a third of all the protein in the human body, more than any other type of protein in the body by mass.
When the human body ages, it lessens the production of collagen, resulting in saggier skin and an older looking appearance.

HIFU uses focused ultrasound energy to target the deeper layers of skin. The ultrasound energy causes the tissue to heat up rapidly. Once the cells in the targeted area reach a certain temperature, they experience cellular damage or trauma . The trauma actually stimulates the cells to produce more collagen resulting in firmer and tighter skin.

This non invasive treatment may have immediate results the ultimate results will take place ver 2-3 month period. There is no down time and carries a lot fewer risks than surgical face lift. Repeated procedures may be needed over time . 
Some clients do not feel much but others might say they feel a sort of minor electric shock feeling as the heat rays enter the skin.

For best results you should have 3 treatments, 3 months in between each one. There is no down time and the treatment carries a lot fewer risks that surgical face lift.
