Hi and thank you for your question! We have seen AMAZING results in treating the arms with coolsculpting! We assess each patient to decide how many cycles per arm, ideally its assessed in person, so we can palpate the tissue to evaluate where the subcutaneous tissue is concentrated, and also use the template for sizing to finalize treatment plan. Sometimes with photos we can give you an idea of what treatment plan will likely be. We usually recommend at least two treatment sessions, but some patients may want to consider a 3rd. Ideally about 6-8 weeks in between treatments, but it can safely be retreated in 4 weeks. Last bit of important info, we have seen (and studies have shown) that when patients use a body treatment from Alastin Skincare called Transform Body Cream, in between treatments, starting right after the first session and possibly even better to start a week or two before, they are seeing accelerated and enhanced results, as well as improvements in texture, skin laxity and crepiness! I without a doubt encourage patients to use this product, especially in an area such as the arms, where skin tightening could be of extra benefit! Best of Luck! Dr. Grant Stevens
