Do you ever only use 3.0 on a small ultherapy face, young, thin layers and ditch 4.5?

Just for better skin but not go deep into the muscle?

Transducers are customised to ones face.

Yes, it really depends on the face. So, if one has laxity that is significant, and the SMAS layer is deep, then sure a 4.5 will be used, however in thinner areas of the face, we can visualise the layers using Ultrasound on the screen, and a 3.0 transducer can be used. The 1.5 is used only to stimulate collagen, as it does not penetrate deep enough to cause a significant lift- it is designed to treat skin texture (decrease fine to medium wrinkles). So, a good Ulterapy provider will ALWAYS customise a program according to YOUR facial features, and apply the lines in areas that you will have the most benefit from. All the best, Dr Davin Lim.

Ultherapy treatments are customized for each patient

There are three transducer depths that are used with Ultherapy which include 1.5 mm, 3.0 mm and 4.5 mm.  The transducer depth that is used completely depends on the patients anatomy.  If a patient has a thin face with thin subcutaneous tissue, a more superficial depth would be used to target the SMAS layer.  The Superficial Musculoaponeurotic System (SMAS) is located below the fat and is a strong tissue that envelops the face. It is made up of collagen, elastic fibers, muscle fibers and fat cells. The ultrasound energy produced during an Ulthera treatment, precisely and consistently heats the targeted tissue to 60-70 degrees centigrade, which is the optimal temperature for contraction and denaturation of collagen. 

It is important to ensure that your ultherapy technician is experienced and is visualizing the ultrasound during treatment.  Ultherapy treatments are customized for each patient. Good Luck!

Ulthera Depths

When having Ulthera, it is imperative your provider do a thorough imaging of your tissue with the Ulthera ultrasound to determine at what depth your muscle lies.  An effective Ulthera treatment involves treating at two levels: the depth of the muscle and one depth above.  If the muscle is at 4.5 mm, the patient would be treated with the 4.5mm and 3.0mm transducers.  However, if the patient's muscle is at 3.0mm, a treatment with the 3.0mm and 1.5mm transducers would be more effective. 

The 1.5mm transducer can be used as a stand alone treatment for patients who are wishing to address just fine lines and wrinkles (this is often done in younger patients).  While the transducer does allow for some lifting, most patients benefit from the dual depth traditional Ulthera treatment.  Consult with an experienced provider who can discuss the different treatment options and determine what will best meet your needs.  It is important your provider is skilled at interpreting the ultrasound and can determine the most effective depths for your treatment.

Ultherapy Treatment

Hello - Ultherapy systems have a screen that allows the Ultherapist to visualize the various layers and precisely target the depth the ultrasound energy is delivered. It is possible to use Ultherapy to treat skin and not subcutaneous fat or SMAS layer just above muscle. Usually, the 1.5 transducer is used for treating the skin. Still, everything is first confirmed by visualizing on the Ultherapy screen.  Make sure you receive your Ultherapy procedure in a board certified dermatology or plastic surgery office for safety and best outcome.

Ultherapy smoothing

The Ulthera 1.5 mm transducer is specifically used to stimulate collagen production in the upper layers of the skin, to improve fine lines and wrinkles. This is a 'stand alone' treatment meaning that it can be and is often done without using the 3.0 and 4.5 mm transducers used in an Ultherapy session that is focused on lifting rather than surface smoothing.
