A birthmark is also known as what?

A birthmark is referred to as a naevus (plural: naevi) in medical terminology. This term encompasses a variety of skin marks that are present at birth or develop shortly thereafter, including pigmented and vascular types. Naevi can appear in different forms, such as moles or hemangiomas, and they can vary in color, size, and texture.

Understanding the terminology related to skin conditions is crucial in the beauty and skincare industry as it allows professionals to accurately identify and communicate about different skin features. The other options represent different types of skin conditions or characteristics: a macula refers to a flat, distinct, and colored area of skin; a comedo is a clogged hair follicle (often referred to as a blackhead or whitehead); and a lesion refers to any abnormal change in the structure of an organ or part, which can encompass a wide range of conditions beyond just birthmarks. Thus, naevus is the most specific and accurate term for what is commonly known as a birthmark.
