What is the medical term for wrinkles?

The medical term for wrinkles is "rhytids." This term is derived from the Greek word "rhytis," which specifically refers to a wrinkle or a fold in the skin. In the context of dermatology and cosmetic treatments, the term is commonly used to describe the natural aging process of the skin where sagging and fine lines develop due to factors like loss of collagen, sun exposure, and other environmental influences.

The other options may describe similar features of the skin but do not specifically denote wrinkles in the medical sense. Dermatitis refers to inflammation of the skin, furrows may suggest deeper or more pronounced lines but not specifically a general term for all wrinkles, and creases can indicate any kind of line or fold in the skin but are often less formal and not specifically aligned with medical terminology. Hence, "rhytids" is the precise term used in clinical settings to identify wrinkles.
