Dermis


The dermis is a layer of connective tissue composed mainly of collagen fibers including about 5% elastin.

The dermis provides the epidermis with nutrients and removes waste products, as well as giving structural support.

The plane of contact between the dermis and the other skin layers is undulating, including papillae (upward projections of the dermis) and rete ridges (depressions of epidermis).

Dermal Collagen

Collagen is an insoluble protein arranged in an orthogonal (basket-weave) pattern.

Type I collagen is also referred to as "new collagen."

Type III collagen is also referred to as "mature collagen."

Mature collagen has a low turnover rate.

Histology shows UV damaged skin has less type I collagen than normal skin (less than undamaged chronologically aged skin).

The ground substance of the dermis (extracellular/intercellular matrix) consists of polysaccharides, glycosaminoglycans and glycoproteins.

Glycosaminoglycans are only 1 % of the dry weight of skin, but able to bind up to 1000 times its own weight in water and have a dramatic effect on skin hydration.

Skin's glycosaminoglycan content is best restored through the Skin Texture Treatment and frequent use of the Gernetic Cells Life Serum.

Hyaluronic acid is one of the main glycosaminoglycans in adult skin.

It is also an excellent "carrier" vehicle for other skin care products when applied topically.
