I'm six months out from my arm lift, and the sagging skin is so much tighter now. My arms look noticeably slimmer, and I can really feel the difference. Short sleeves fit so much more comfortably — I'm really happy with it.
The scarring was what worried me most, but the redness has faded a lot and it's still lightening. It sits along the inner arm, so you'd hardly notice it day to day. The bruising and the worst of the swelling were mostly gone by the one-month mark.
The early recovery is the hard part, but once you get through it, the difference in your arm line is real. I'm really glad I did it.
