Skin seems to become looser over time and this happens for a number of reasons. Center for Dermatology & Plastic Surgery has options to tighten skin on the face and body.
One cause of skin becoming looser is due to the effect of environmental stress on elastic fibers and collagen fibers in the skin. Environmental stress can be sun, pollution, diet and even just plain stress. In addition, we lose facial volume because our facial fat pads diminish as we age.
As a result the breakdown of these fibers causes laxity, increasing over years. Gravity combined with volume loss pulls the looser skin downwards. The face will show some “jowling” as early as the 30′s. Puffiness and bags under the eyes can also be due in part to skin laxity.
