Freckles
Freckles
Freckles (/ˈfrɛkəlz/) are small, flat, brown spots that appear on the skin. They are a common skin condition that can occur in people of all skin types, but are most common in individuals with light skin and hair.
Etymology
The term "freckle" comes from the Middle English freken, which, in turn, comes from the Old Norse freknur, meaning "spots".
Definition
Freckles are a type of pigmentation in the skin. They are caused by an increase in the production of melanin, the pigment that gives skin its color. Freckles are usually tan or light brown, and they typically appear on the face, although they can appear anywhere on the body.
Causes
Freckles are primarily caused by exposure to the sun. The skin produces more melanin in response to sun exposure in an attempt to protect the deeper layers of skin from damage. This increased melanin production can cause freckles to form. Genetics also play a role in the development of freckles, as individuals with a family history of freckles are more likely to develop them.
