What is epidermal thickening?
Epidermal thickening is the process by which the outer layer of the skin, the epidermis, becomes thicker than usual. This can happen in response to various factors such as excessive sun exposure, friction, certain skin conditions, or as a normal part of aging. Epidermal thickening can lead to rough, calloused, or hardened skin that may be more prone to certain issues like dryness or cracking.
