Aloe vera has natural skin-tightening properties that can help get rid of sagging breasts. The antioxidants in aloe vera prevents damage caused by free radicals and help firm sagging breasts. Apply aloe vera gel onto your breasts and massage gently in a circular motion for 10 minutes. Allow it to sit for another 10 minutes and then wash it off with warm water. Repeat this remedy 4 or 5 times a week to get effective results. You can also prepare a mixture of 1 tablespoon of aloe vera gel and 1 teaspoon each of mayonnaise and honey. Apply this onto your breasts and leave it on for 15 minutes. Rinse it off first with warm water and then use cold water. Do this once a week.
