What is Dermatology?

The study of a vast field of knowledge about the physiology and pathology of the skin and hair, nails, sweat glands, and oil glands. Robert Willan in England (1757–1812) was the first to publish and classify information about skin disease, which was further explored by Jean-Louis Alibert (1768–1837) in Paris, who considered each dermatosis as a specific branch of dermatology. But it was not until the discovery of the microscope that dermatologists were able to see the skin in all its structural and cellular detail. At the same time, the infant science of bacteriology revealed the secrets of infectious diseases such as impetigo and boils.
