Ultrasound lifting: how much does it actually lift?
In short
In a 2023 systematic review, objectively measured changes were in millimeters: brows raised by 0.47–1.7 mm and the area under the chin reduced by 26–45 mm². The change appears gradually over the months it takes collagen to rebuild, so judging after one month is too early. Results varied by study population, device and settings, and the same change cannot be expected for every individual.
Key points
- (1).
Focused ultrasound creates tiny heat-coagulation points at set depths under the skin, and the tissue tightens as the skin repairs them and makes new collagen.
- (2).
In the 2023 review of 16 studies, at 90 days clinicians rated 92% improved (n=337) but only 42% of patients felt improved (n=81), rising to 53% at 360 days.
- (3).
Severe existing laxity and a BMI over 30 were listed as relative contraindications because results were poorer; effects were shown in mild to moderate laxity.
- (4).
Treatment involves moderate pain and temporary redness, and other adverse effects such as altered sensation, bruising, burns over the jawbone, linear marks and contact dermatitis were reported rarely, in 2%.
- (5).
The review has no follow-up beyond 1 year, all studies involved women only, and device settings and protocols varied between studies.
FAQ
How long does it last?
In the cited studies (all in women, with varying devices and settings), improvement was reported up to 1 year; there are no data beyond that, and individual results vary.
Does it hurt?
The paper describes the pain as moderate. It varies with the area and energy settings.
If it does not work, should the energy be turned up?
Raising the energy also raises the risk of burns and altered sensation. If the limited effect is due to the degree of laxity, more energy will not solve it.
