How does the dermis maintain homeostasis?

The skin’s immense blood supply helps regulate temperature: dilated vessels allow for heat loss, while constricted vessels retain heat. The skin regulates body temperature with its blood supply. The skin assists in homeostasis. Humidity affects thermoregulation by limiting sweat evaporation and thus heat loss.

Does the dermis functions as padding and insulation?

Below the dermis lies a layer of fat that helps insulate the body from heat and cold, provides protective padding, and serves as an energy storage area.
