What Causes Dimples?
A dimple is a dent or depression in the skin on a part of the body where the flesh is soft. The fibers which lay in the tissue under the outside skin help to hold the skin firm. These fibers which are, of course, small run in all directions and are of different lengths. Now and then these fibers will just happen to grow short in one spot or the other and pull the skin in, forming a little depression, but producing a very pleasing effect.
