Layer 02, Collagen and elastin

Dermis

The structural layer where firmness, bounce and resilience live.

Depth

Approximately 1 to 3 mm thick on the face

The dermis sits beneath the epidermis and is the connective layer of the skin. It is largely composed of collagen and elastin, woven into a scaffolding that gives skin its strength, bounce and ability to recoil. It also houses blood vessels, nerves, sweat glands, sebaceous glands and hair follicles.

What it is

The dermis is a dense matrix of fibroblasts producing collagen, elastin and ground substance, including hyaluronic acid. Collagen provides tensile strength. Elastin allows the skin to stretch and recoil. Hyaluronic acid binds water and contributes to hydration and plumpness.

Blood vessels in the dermis nourish both the dermis and the overlying epidermis. Nerves here detect touch, temperature and pain.

What it does

Provides the mechanical scaffolding that supports the overlying epidermis.

Holds water in the deeper skin, contributing to fullness and a smooth surface.

Houses the vascular and sensory networks of the skin.

How it changes with age
  • Fibroblast activity may decline, with associated reductions in new collagen and elastin production.
  • Existing collagen and elastin fibres may fragment over time, particularly with cumulative sun exposure.
  • These changes are associated with fine lines, crepiness, loss of bounce and a less even surface.
Categories of treatment that work at this layer
  • Bio-remodelling and skin needling approaches that work within the dermis to stimulate the skin's own repair processes.
  • Biostimulator categories that target collagen production over months.
