Do I need an arm lift or arm lipo?

Mahalo for your photos. You are a candidate for either liposuction and/or energy based contraction methods to achieve smaller diameters and tighter arm contours. The risks to be considered are scars at the entry portals and possible contour irregularities. Arm lifts carry risk of larger, more visible scars and may not be that effective for your situation (not recommended). Consult with experienced board certified surgeons before any procedure.

Based on your photos you do not have any degree of. Saggy skin so Liposuccion will be a great option for you.

From your photos, you appear to be a good candidate for BodyTite with liposuction of the arms. BodyTite does not remove any fat, but it is capable of producing a 45% contraction in tissues. Results can be seen immediately after one treatment and are more evident over three to six months post-treatment. Wait until six months to fully evaluate the aesthetic results. Sedentary activities can be resumed in two to three days and full activity with exercise within two to three
