Thanks for your question. Sofwave actually does have an FDA clearance for 'temporary improvement in cellulite' which is via its skin tightening effect, so we know it is effective for the skin in this region. the thing that might be limiting is the size of the region you want to treat. To treat the full thighs all the way around, for example, is not feasible in one session...in terms of time but also importantly in terms of topical lidocaine dose. Too much topical lidocaine applied in one session could lead to lidocaine toxicity, as some of the topical medication does get absorbed but the body. So, a session of Sofwave would need to be limited to, say, just the back of the thighs, or just the inner thighs, or just above the knees or example. Over time, you could do more regions if need be, budget permitting. I hope that is helpful to you.
