skin ligament (retinacula cutis)

One of numerous small fibrous strands that extend through the superficial fascia, attaching the deep surface of the dermis to the underlying deep fascia, determining the mobility of the skin over the deep structures. These are especially well-developed over the breasts where they are known as the suspensory ligaments of the breast. They are also well developed, but short in the palms of the hands & soles of the feet.
