What are the main layers of the skin involved in regeneration?
The skin is composed of three primary layers: the epidermis, dermis, and subcutaneous tissue. The epidermis, the outermost layer, is primarily responsible for regeneration. It consists of keratinocytes, which proliferate and migrate to replace lost or damaged cells. Beneath the epidermis lies the dermis, which contains fibroblasts, collagen, and elastin fibers that provide structural support. The subcutaneous layer, composed mainly of fat, serves as insulation and padding but plays a lesser role in regeneration.
