Two Distinct regions of the integumentary system: epidermis & dermis. Underneath dermis is hypodermis (superficial fascia), also called subcutaneous tissue which is composed of loose connective tissue (mostly areolar and adipose).
A collagen facial is a treatment designed to restore the depleted collage in your face and rejuvenate your skin. Ultimately, a collagen facial will slow down the aging process by replenishing your body's natural proteins through external applications.
In addition, collagen provides a natural scaffold or substrate for new tissue growth. Collagen dressings stimulate new tissue growth and encourage the deposition and organization of newly formed collagen fibers and granulation tissue in the wound bed. These dressings chemically bind to matrix metalloproteinases (MMPs) found in the extracellular fluid of wounds.
