rapid cell division in skin's outermost layer
Epidermal proliferation refers to the process by which cells in the outermost layer of the skin, known as the epidermis, rapidly divide and multiply. This process is crucial for skin regeneration and repair, helping to replace dead or damaged cells and maintain the skin's protective barrier. In conditions like psoriasis, this proliferation can become excessive, leading to thickened, scaly patches of skin.
