The main causes of sagging is due to loss of fat and support structure under the skin due to aging or after weight loss from slimming. One further reason is that the skin also thin out during aging with decreased collagen and elastin fiber to support the skin. The gravity then exert its toll by allowing every structure of the skin to slide down.
After significant weight loss, the subcutaneous fat is lost by a big amount. The overlying skin lost the support and begins to slide down. The worst place to see the sagging is the abdomen area causing flabby redundant extra skin. Other area includes the thigh, buttock, under arm, chin, and of course the face.
In general, during the pregnancy, the mother can put on 10 kg body weight. After the delivery, easily there are still 7 kg weight gain. Pregnant state of abdomen is over stretched causing the skin loosing its elasticity. Post delivery, the abdomen shrink back in size but the skin collagen and elastin fibers are broken, thus losing its recoil ability. This cause the skin flab to drop down causing sagging appearance.
The face sags the most during aging and even in extreme slimming course.
During aging, the skin under the eye shows the tear trough line, also called the nasojugal line due to lost subcutaneous fat. The area immediately above this line shows bulging skin contained in it is the fat globule. The fat moves forward causing eye-bag.
Various lines and folds appears after crash course slimming or during aging process. They includes the nasolabial also called the power line, the marionette line, the mental lines at the chin.
This is most prominent after extreme slimming. The aging also adds the double chin significantly due to the loose skin.
During the aging, the skin as well as the muscle of the neck weakens and causing the folds develop in the neck called the turkey neck bands.
Most common is the sagging of the abdomen skin after slimming. The best way to treat this is by tummy tuck.
This is also another area that is difficult to treat. In extreme case, a tuck of the thigh is necessary.
This is the most difficult area to treat. This is the result of slimming and aging process combined. The best treatment is tuck rather than a liposuction.
