What is the difference between HIFU and Ultherapy?

When people ask about non-surgical options for laxity of the face and neck, the two names that come up most often are HIFU and Ultherapy. Because both use the same type of energy, they are often confused. This article gives a general overview of what the two treatments have in common and how they differ.

What they have in common

• Both use focused ultrasound energy. The energy reaches the deep dermis and the supporting layer called the SMAS without harming the skin surface.
• The controlled heat created in these layers stimulates the body's own collagen production.
• No incisions are needed. Most people can return to daily life on the same day.
• Because collagen production takes time, changes appear gradually over weeks. Results vary from person to person.

The key difference: imaging

Ultherapy is a system that can display the tissue layers on a screen during the treatment. The physician can see the layers beneath the skin and plan the treatment before delivering the energy.

With HIFU devices, the treatment is delivered at depths defined by the handpieces. With both methods, how the treatment is carried out is decided by the physician's assessment.

What happens during the treatment?

The two treatments follow a similar course:

1. At the consultation, your skin and expectations are assessed and suitability is decided.
2. The skin is cleansed, the treatment area is marked and ultrasound gel is applied.
3. The energy is delivered in lines with the device's handpiece. The duration depends on the area.

You may feel warmth and a prickling sensation during the treatment. Comfort measures can be taken if needed. Temporary redness, mild swelling and tenderness may follow.

Which one suits you?

There is no single answer that applies to everyone. Skin type, the degree of laxity, the area to be treated, expectations and medical history are assessed together. Marked excess skin may require a surgical assessment. Which method suits you is decided together at the consultation.

These treatments may not be suitable during pregnancy and breastfeeding, if there is an open wound or active infection in the treatment area, or if there is a metal implant, pacemaker or similar device in the area. Please tell us about any medications you take and any illnesses you have had at the consultation.
