Would brachioplasty remove stretch marks on the arms?

The only stretch marks that will disappear are those which are removed with the skin excision. Sometimes the stretch marks which are not removed, look a little better under tension. This might be a nice bonus, but you should not necessarily expect this to be a result.

Brachioplasty typically takes away the badly stretched thinned skin on the inner arm away. It isn't guaranteed to remove them entirely but the majority are in most cases.

When a classic brachioplasty is performed, the significant amount of skin is removed usually from the back part of the upper arm. If stretch marks are within the skin that is removed, they are treated. If stretch marks are in the skin that remains, they will not be helped by brachioplasty surgery.
