Dermatologists are medical doctors who specialize in diagnosing and treating conditions related to the skin, hair, and nails. They handle a variety of issues, including acne, eczema, psoriasis, and skin cancer. Dermatologists also perform cosmetic procedures, such as Botox injections and laser treatments, to enhance the appearance of the skin. In addition to treating diseases, dermatologists educate patients on proper skin care and sun protection. They often work with other healthcare professionals to provide comprehensive care for conditions that may affect the skin, such as diabetes or autoimmune disorders. Their expertise is essential for maintaining healthy skin.
