Background High‐intensity focused ultrasound is approved by FDA for both upper face and lower face, neck laxity and for decollete rejuvenation. It produces micro‐focused thermal damage on the dermis and superficial muscular aponeurotic system layer at precise depth and with this thermal stimulus the collagen denaturation and subsequent neo‐collagenosis occur. High‐intensity focused ultrasound (HIFU) effects on body laxity has also been used in some studies but it has not been approved yet. Aims To find out the efficacy of HIFU for the treatment of upper under arm laxity. Patients/Methods We used HIFU device with the new transducers; 13 mm depth 4 MHz and 2J for under arm laxity for 5 patients. Results All patients showed a clinical improvement according to the physicians and patients assessment scales. The side effects were mild erythema and edema during the treatment and tenderness which lasted in 10 days. We follow up our patients in a one year period, and there were no side effects. Conclusion HIFU can be used for upper arm laxity treatment with the new transducers developed for body areas.
