    GlossarySkin Surface

    outermost layer of skin acting as a protective barrier

    The skin surface refers to the outermost layer of the skin, known as the epidermis. It acts as a protective barrier against environmental factors, such as pathogens and UV radiation, and plays a crucial role in regulating moisture and temperature. For professionals, understanding the skin surface is essential for diagnosing and treating various dermatological conditions, including alopecia, which can be influenced by the health and integrity of this layer.
