The crepey, loosened skin of the inner upper arm is a use Ultherapy is FDA-cleared in the US for: skin laxity on the anterior and posterior arms, cleared in February 2025 with the abdomen. The clinician runs lines of focused ultrasound under the skin of the inner and the back of the arm at the depths chosen from the image. The heat builds new collagen over three to six months so the skin tightens. Both arms in one session, with the price in writing at a free consultation at Ultherapy London, 130 Harley Street.
What it does on the arms
The skin of the inner arm firms and the crepey texture smooths; loose, hanging skin after a large weight loss is more than Ultherapy lifts. A soft layer over a triceps that has lost tone is a muscle question, where EMsculpt NEO, which we also provide, is added, with the order planned at the free consultation.
What the evidence covers
The 2025 clearance rests on a review of published studies: five on the arms with 113 people, which showed clinically significant improvement up to six months after treatment, with no unexpected or severe side effects. The full guide sets out the face and neck studies.
The session and the result
About 45 minutes for both arms, with a comfort plan agreed beforehand; redness for a few hours, swelling for a day or three, tenderness for up to two weeks. The result builds over three to six months, when we photograph it, and holds for around a year in our experience.
Price and booking
Both upper arms are priced as an area, in writing at your free consultation, with a price match on any comparable written quote and interest-free finance through Humm, subject to status. Call Ultherapy London on 0207 043 8109 or use the form below; the full Ultherapy guide covers the rest.
