Ultrasound delivers focused ultrasound energy at depths of up to 5mm, generating minimal heat into the skin non-invasively from the inside-out (unlike lasers and radio-frequency treatment which penetrate the skin from the outside-in). It creates a progressive thermal rejuvenating effect down to the adipose tissues that stores energy and insulates the body. In short, this part of the procedure breaks down the fats, and favours fat volume reduction in the submental zone. It also activates the skin’s natural regenerative process by increasing the collagen tissue extensibility. Results of facial remodelling and lifting of the skin can be seen progressively within 40 days.
