Can a breast lift help smoothen or remove some stretch marks on the top of the breast?

Dear Fantastic750344,
it is hard to tell for sure without an examination. It will remove excess skin and lift your breasts so it might also improve some stretch marks. I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

During a breast lift, only some skin is removed from the breast, so whatever stretch mark are inside the pattern of the breast lift are removed during the lift. If the scars are outside of the pattern of the breast lift, they will remain after the breast lift. Best wishes..
