A dermatologist is a healthcare professional who specializes in skin, hair, nails, and the tissue beneath them. They can also perform surgeries when necessary. Dermatology is all about addressing a wide array of skin concerns, which is super important since your skin is the largest organ in your body. It acts as a barrier against damage, infections, and environmental factors, so it’s no wonder people seek out dermatologists for help with everything from common issues like acne and eczema to more serious conditions that might arise from trauma or genetic problems.
