Skin is an organ which protects us from the environment, controls our body temperature and prevents our body from losing fluid and electrolyte balance.
Skin can be generally divided into three main parts:
The outer part (epidermis) contains skin cells, pigment, and proteins.
The middle part (dermis) contains blood vessels, nerves, hair follicles, and oil glands. The dermis provides nutrients to the epidermis.
The inner layer under the dermis (the subcutaneous layer) contains sweat glands, some hair follicles, blood vessels, and fat.
Each layer also contains connective tissue with collagen fibers to give support and elastin fibers to provide flexibility and strength. Collagen and elastin are the components that make the skin firm
The skin can become sagging when it loses collagen and elastin. The most common cause of skin sagging is aging and the skin becomes thinner and looser. Other factors contribute to the sagging skin on the face: skin dehydration, loss of facial fat. Facial muscles tension, weak, tendon inflammation and reduction of blood circulation to the skin are also contributing to the sagging skin.
Acupuncture can reduce muscle tension and tendon inflammation, increase skin elastin and collagen synthesis and hydration and stimulate skin remodeling. As a result the facial skin becomes tighter and firmer. This gives you the younger looking skin.
