Hello and thank-you for your question. Non invasive treatment, such as Coolsculpting are attractive because there is no down time or recovery, yet I do not think that you will achieve your desired goals without surgery.CAST Liposuction combined with minibrachioplasty produces excellent upper arm contourLiposuction for upper arm contouring can produce excellent results in individuals with good skin laxity. I recommend the Circumferential para-Axillary Superficial Tumescent (CAST) technique for upper arm contouring. The use of tumescent anesthesia, micro cannula, and meticulous post operative care maximizes skin retraction and can give excellent improvement. If there is skin laxity, a brachioplasty may be required to tighten the skin. The minibrachioplasty is ideal for correcting the loose skin in the upper third of the inner arm. An ellipse of skin is removed from the axilla (arm pit) and the thin skin of the upper inner arm is advanced and tightened. The scar generally heals well and is well hidden, allowing you to wear short sleeves and sleeveless blouses. A photo of areas would be helpful. I would recommend an in person consultation with a Board Certified Plastic Surgeon well versed in body contouring. Best wishes, Andrew Lyos MD, FACS
