What is the dermis, and why does it matter?

Where is the dermis?

The dermis is connective tissue between the epidermis and subcutaneous tissue. It contains blood vessels, nerves and skin appendages.

How do its two regions differ?

The superficial papillary region borders the epidermis and contains relatively loose connective tissue. The deeper reticular region contains larger fibre bundles. These are regions of one continuous tissue, not separate organs.

Are collagen and elastin the same thing?

Collagen contributes strength; elastic fibres allow stretching and recoil. Fibroblasts produce and maintain these fibres and the surrounding matrix.

What does this mean for aesthetic technology?

A claim that a procedure affects the dermis does not by itself establish that the procedure is necessary, safe or effective for a particular person. The exact device, its intended use, the quality of research and the ability to manage complications all need clarification.

Ask what improvement the practitioner expects and how it will be assessed. “More collagen” should not be the only answer. Photographs, measurements and a person’s experience provide different types of information; it helps to know in advance which the clinic will use.

How should we assess “improving dermal quality”?

That phrase needs explanation. Ask precisely what “quality” means and how it will be evaluated. Someone’s opinion of their skin’s appearance, a standardized photograph and an instrument measurement are not interchangeable answers. This distinction also helps when reading research or an offer. Defining the goal in advance helps you later assess the change that originally led you to consider a procedure.
