What is the medical term for a wrinkle?

The term "Rhytid" derives from the Greek word "rhytid," which means wrinkle or fold. In medical terminology, it specifically refers to a wrinkle in the skin, making it the most precise choice when describing this particular skin condition.

While "furrow" can also refer to a line or groove in the skin, it is a broader term that can apply to various types of skin indentations and is not exclusively limited to wrinkles. "Dermatopathy" refers to any disease of the skin, not specifically to wrinkles. "Lentigo" pertains to a type of pigmented spot on the skin, usually related to sun exposure, and is unrelated to the concept of wrinkles. Therefore, rhytid is the appropriate medical term for a wrinkle.
