An arm lift – also known as a brachioplasty – is a type of procedure that sees excess skin and fat between the armpit and the elbow being removed. This is achieved by making small incisions on the undersides of your arms, tightening the underlying tissues and then securing them with stitches. Many opt to undergo an arm lift should they feel that they’re underarms sag or appear loose, and feel that they would benefit from a tighter appearance.
