A mastopexy (more commonly known as a breast lift) is a surgical procedure designed to lift sagging breasts and restore the more youthful, shapely profile you enjoyed before age, fluctuations in weight, and breastfeeding began to adversely affect their appearance. Changes in your body after pregnancy and breastfeeding may have left your once full breasts looking droopy and deflated. When combined with the pull of gravity and the natural decrease in collagen and elastin in your skin as you age, the result is loose, excess skin, asymmetries in your breast size and shape, as well as nipples that aren’t as perky as they used to be.
