ephelis

A child has a small ephelis on their cheek.

Definition

1. Noun (countable, plural: ephelides):
   • Medical term: An "ephelis" is a small, brownish spot on the skin, commonly known as a freckle. It is caused by an increase in melanin production due to sun exposure, and it is typically harmless. Ephelides are most common in people with fair skin and often appear on sun-exposed areas like the face and arms.

Usage Examples

• (Small brown freckles caused by sun exposure.)
• (Medical professionals check these spots for safety.)
• (Freckles may change with sun exposure.)

Advanced Usage

• "Ephelis vs. lentigo": In dermatology, an ephelis is a temporary, sun-induced freckle that may fade in winter, whereas a lentigo is a permanent, age-related spot. This distinction is important for diagnosis.
  • The doctor noted that the spot was an ephelis, not a lentigo, because it lightened during colder months. (Differentiating between types of skin spots.)

• Ephelidal (adj): Relating to or resembling an ephelis.
