Collagen is found in the dermis layer of the skin. Collagen forms the structure in which the epidermis layer (the top layer) of your skin rests. Over time, collagen production can decrease, which breaks down the foundation of the skin giving the skin a tired, lusterless look. Cosmetic Acupuncture stimulates collagen production by needling the dermis layer allowing your skin to produce more collagen. Also, by needling certain acupuncture points, the body can produce more collagen.
