Quick answer
HIFU (high-intensity focused ultrasound) heats precise points in the deeper layers of the skin, without incisions, to stimulate collagen production. It can help with mild to moderate laxity of the face, neck and décolletage. Improvement is gradual over weeks and varies from person to person.
How HIFU works
The device focuses ultrasound energy at set depths of the skin and supporting tissue. Controlled heating stimulates collagen renewal, which may contribute to firmer skin over time.
Who it may suit
It may suit mild to moderate laxity, a less defined jawline or neck and décolletage skin with less firmness. With marked laxity results are more limited and the doctor may suggest other options, such as PDO threads or a collagen biostimulator.

How the session works
After cleansing, a gel is applied and the device is passed over the agreed areas. You may feel heat and some discomfort over bony areas. You can usually return to normal activities the same day.
Aftercare and possible side effects
Redness, mild swelling or tenderness may appear in the following hours or days. Daily sun protection is recommended. The doctor will tell you if and when a repeat makes sense.
