There is a new technique called The Mini Ultimate Breast Lift, which uses only a circumareola incision to reshape your breast tissue creating upper pole fullness, elevate them higher on the chest wall and more medial to increase your cleavage. Unfortunately, you have not provided any photographs or your bra size. This technique produces the least scars and you may be a candidate.
