Freckles are small, concentrated spots of melanin on human skin. They are also known as ephelides (singular: ephelis). Freckles are typically found on individuals with a fair complexion and are more common in people with red hair. They are usually visible on areas of the skin that are frequently exposed to the sun, such as the face, arms, and shoulders.
Causes[edit | edit source]
Freckles are primarily caused by a combination of genetics and sun exposure. The MC1R gene is often associated with the development of freckles. When skin is exposed to ultraviolet (UV) radiation, it triggers the production of melanin, which can lead to the formation of freckles.
Symptoms[edit | edit source]
Freckles appear as small, flat, and circular spots that are usually tan or light brown. They can vary in size and number and are most commonly found on sun-exposed areas of the skin.
Diagnosis[edit | edit source]
Freckles are typically diagnosed through visual inspection by a dermatologist. They are distinguished from other skin conditions such as lentigo and melanoma by their appearance and distribution.
Treatment[edit | edit source]
While freckles are harmless and do not require treatment, some individuals may seek cosmetic treatments to reduce their appearance. Common treatments include:
- Laser therapy
- Topical creams containing hydroquinone or retinoids
Prevention[edit | edit source]
Preventing freckles involves minimizing sun exposure and protecting the skin from UV radiation. Recommended preventive measures include:
