Can a mini arm lift be performed on the lower portion of the upper arms only? (Photos)

Yes, what you're describing is actually a very common concern and, in many cases, a mini arm lift or limited-incision brachioplasty can absolutely target just the lower portion of the upper arms — specifically the area near the inner arm, close to the elbow.
Here’s a quick breakdown for you:
Mini Arm Lift for Lower Arm Skin Laxity
• Target Area: Can focus on loose skin confined to the lower part of the upper arm (the "distal" upper arm), especially if it's limited to the last 2–3 inches above the elbow.
• Incision Location: Typically, a short, discreet incision can be made within the natural creases of the arm or just above the elbow area, depending on your anatomy.
• Candidacy: If your skin laxity is mild to moderate and well-localized, you’re likely a good candidate for this more conservative approach.
Benefits
• Smaller scar, often hidden or less noticeable
• Faster recovery compared to a full arm lift
• Avoids the long scar that typically extends from the armpit to the elbow in full brachioplasty
Things to Keep in Mind
• Skin Elasticity: If your skin is too loose, a mini arm lift may not provide adequate tightening, and your surgeon might recommend a slightly longer incision for best results.
• Surgeon Expertise: Not all surgeons offer short-scar arm lifts, so you’ll want to consult with one experienced in tailored, minimal-scar procedures.
• Possibly Combine: Some patients combine this with non-surgical skin tightening (like radiofrequency or laser) to improve results in borderline cases.
I recommend scheduling a consultation with a board-certified plastic surgeon who specializes in post-weight loss body contouring. They can evaluate whether a mini lift, a skin-only excision, or possibly a combination of minor lift and skin tightening would be your best option.
