Freckles are a type of skin lesion that occurs on the face. They appear as small, spotty or sesame-like brown or light brown spots.

It is common on the face, especially the nose and cheeks, and can affect exposed parts such as the neck, shoulders, and back of the hands. There is no rash on non-exposed parts.
