Perky, but scars
A breast lift
removes excess breast skin and repositions nipple/areolas to higher, more youthful position (usually without removal).
But, there are permanent scars (that fade) and 15%+ risk of absent nipple sensation. If you smoke, there is a risk of poor circulation and dead skin causing worse scars. Infection, asymmety, and bad scars are rare, but possible. See an abps-certified plastic surgeon.
