"What does a dermatologist do?"

A dermatologist is a physician who specializes in the diagnosis and treatment of disorders of skin, nails, and hair.

What's the largest organ in your body?

Answer: Your skin!

On an adult, skin has an average surface area of 22 square feet-about the same as space covered by a roll of wallpaper. It weighs eight pounds-give or take a pound or so. Waterproof and stain-resistant, skin keeps fluids like blood and water inside your body while protecting you from disease-causing pathogens and guarding your internal organs, bones and tissue. But skin is more than just the body's natural wetsuit. It contains a complex network of cells, nerve endings, blood vessels, sweat glands and oil glands. And they all perform a multitude of tasks key to your well being. For instance, the nerve endings in your skin recognize important sensations, including touch, pressure and pain. They sense whether you're hot or cold-and help regulate your temperature by sending signals to your blood vessels and sweat glands. The skin makes steroids and hormones-and white blood cells that battle disease-causing microbes and trigger immune system reactions within your body. Yes, there's a lot more to your skin than meets the eye. That's why the job of the dermatologist is so important.
