Which term refers to the art and science of beautifying and improving the conditions of finger nails, toenails, and the surrounding skin?

The term that specifically encompasses the art and science of beautifying and improving the conditions of fingernails, toenails, and the surrounding skin is Nail Technology. This field focuses on the skills, techniques, and practices involved in maintaining and enhancing nail health and aesthetics through various methods, including manicures, pedicures, nail art, and treatments.

While Beauty Therapy, Cosmetology, and Manicure Services relate to the broader scope of beauty treatments, Nail Technology is particularly specialized in the nail care aspect. Beauty Therapy includes a wider range of services, such as skin and body treatments. Cosmetology covers hair, skin, and nails comprehensively but does not concentrate solely on nails. Manicure Services refer to the specific service for hands and nails but does not encapsulate the overall discipline or education dedicated to nail technology as a whole. Therefore, Nail Technology is the most accurate term for this specialized field.
