Skin is a dynamic, protective organ that grows, stretches, shrinks, creases, and wrinkles in response to a person's age, habits, weight fluctuations, and the environment. Skin serves many important functions including:
- protecting the body from environmental factors such as bacteria, fungus, viruses, allergens, water, and chemicals
- regulating body temperature by sweating and adjusting blood flow to the skin
- synthesizing vitamin D
- helping the body sense touch, pain, temperature, pressure, and position
- providing some protection against the sun's harmful ultraviolet rays via the skin protein melanin
