Thread Lifts vs Ulthera - David Loh Surgery, Aesthetic Clinic | aesthetic |
The face is not made of skin alone. Under the skin, and pretty much in continuation with it, are the fat pockets, fibrous tissues, muscles of the face as well as ligaments. Together they make up the fibro-muscular layer is also called the SMAS.

This is the layer which surgeons tighten during a surgical-facelift. It is also the layer which many thread lifts target. Thread liftprocedures like the Silhouette Threads or the Endotine Threadlift pull on the SMAS to create the lift. But these are semi-invasive procedure where we deliberately anchor the threads to the SMAS layer for the lifting effect. And as such, one can expect some recovery time in the form of bruises and swelling.

With Ulthera, we can target the SMAS selectively and non-invasively. That is to create a non-surgical SMAS Lift.

Because it is non-surgical, there is no recovery-time. But the Ulthera is by no means any less accurate or precise as compared with surgical methods. With a built-in ultrasound scan, the Ulthera can accurately locate the SMAS and deliver a very precise dose of energy to it. This results in the immediate contraction of the fibro-muscular layer and a lifting of the face – an effect that is probably due to mild swelling. Collagen regeneration then goes on for another 3-6 months.

Thermage actually only tightens the skin of the face, so technically it isn’s a SMAS Lifting device.

Hence, when we talk excitedly about skin-tightening, we are actually talking about tightening mainly the tissues immediately under the skin which is collectively called the Superficial muscular aponeurotic system (SMAS).
