Dermatology is a medical specialty that focuses on diagnosing and treating the skin, hair and nails. Skin acts as a barrier, protecting the body from daily exposure to germs and toxic substances. Through the sweat glands, the skin also helps regulate body temperature. Responsible for the sense of touch, the skin (along with the nervous system) alerts the body to potential dangers by sensing pressure, pain, heat, and cold. Healthy skin is important as it produces vitamin D when exposed to the sun, and vitamin D promotes the body’s absorption of calcium, essential for healthy teeth and bones.
Examples of skin, hair and nail conditions include: psoriasis, alopecia, and onychomycosis. With the skin being the largest organ of the body, there are a number of other conditions to study such as: acne, eczema, hidradenitis suppurativa and vitiligo (to name a few).
