Loose upper-arm skin
Loose upper-arm skin hangs or folds away from the underlying contour. It commonly develops with age or after substantial weight loss and may coexist with local fat. Muscle tone improves shape but cannot remove a large skin envelope.
What you may notice
- Skin hanging from the underside of the arm
- Crepey texture or folding
- Laxity after weight loss
- Chafing or clothing difficulty
Why it can happen
Loss of collagen and elasticity, genetics, sun exposure and the amount and speed of weight change influence recoil. Age-related muscle and fat changes can make looseness more visible.
What may help
Stable weight and resistance training improve contour and function. Energy devices may offer limited tightening for mild laxity. Brachioplasty removes excess skin, usually leaving a long inner-arm scar; liposuction may be combined when fat is present but can worsen laxity if used alone.
When to consult
Consult a clinician for sudden swelling, pain, weakness or one-sided change. Surgical consultation should cover scar placement and healing risk.
