ultrasound skin laxity treatment


Skin laxity is a problem that affects everyone; as we age, our skin loses collagen and elastin, proteins that help keep it firm and plump, which causes a loose or sagging look. This FDA approved treatment can be used as a preventive measure or to treat an existing problem to lift the face and tighten the neck in the long term.

Introduction to Ultrasound

Ultrasound treatment (High Intensity Focused Ultrasound) can be used to control this laxity by delivering precisely targeted controlled pulses of ultrasound to areas of concern, which starts a process called thermal coagulation. This causes existing collagen fibres to denature, which stimulates new collagen synthesis and regeneration. 


This is a non-invasive treatment that does not negatively affect the outer layer of skin, bypassing the surface to deliver energy to the deeper layers to promote collagen production.

Areas that can be treated with Ultrasound

Ultrasound treatments can be used to address loose skin on the décolletage, jawline, eyebrows, chin, neck, nasolabial folds (between the nose and mouth), and eyelids, as well as being able to affect uneven skin tone and texture, and even reducing the size of large pores.


Results are noticeable almost immediately in some cases, and continue to improve for up to a year after treatment, with no downtime.
