Dermis

Skin Structure

진피

The thick layer beneath the epidermis, where supporting fibres such as collagen and elastin gather together with blood vessels, nerves, sebaceous glands and hair follicles.

What kind of layer it is

The dermis is the layer that effectively determines the firmness and thickness of the skin. Fibroblasts produce collagen and elastin to form a mesh structure, and substances such as hyaluronic acid fill the spaces between them to hold water.

Good to know

A considerable number of procedures related to firmness and fine lines target this dermal layer. However, the depth and thickness of the layer differ by area and by person, so responses to the same procedure may vary from person to person.
