What are skin conditions?
The largest organ we have is not on the inside of our body but the one we wear on the outside: our skin. Our skin protects all of our internal organs, bones, muscles, and circulation. Our skin helps us keep warm, allows us to sweat and cools us down on hot days. It also absorbs vitamin D from sunlight. You could say that our skin is the most important organ we have.
Adults carry eight pounds and approximately 22 square feet of skin. So you can imagine the problems we might develop with such a large organ. Skin conditions are many and varied. They can range from cuts and scratches to red and itchy rashes and more serious problems like cancer. Our skin is what people see when they look at us, so its health can even impact our self-esteem.
Skin conditions can come on suddenly or develop over time. Some are genetic and impact people from birth. Some of the most common skin conditions are acne, rash or hives, psoriasis, eczema, rosacea, lupus, and different cancers. The medical term for skin is “dermis”, so the study of these different skin disorders is called dermatology. If you have a skin problem, your doctor might recommend you see a specialist called a dermatologist to determine the best treatment plan for you.
