FRECKLES AND MOLES

Freckles are pale brown spots on the surface of the skin that are usually a direct result of prolonged sun exposure. Freckles can also appear as a result of genetics. Moles are distinctively darker than freckles, are long-lasting, and are also related to both genetics and sun exposure.

Both freckles and moles are exceedingly common and are more easily identified in individuals with light skin. On average, a typical adult has 10-40 moles. Most moles begin growing by the age of 10 and continue until mid-adulthood. In adolescents, moles will grow as the child grows.

WHAT CAUSES MOLES TO FORM?

These spots are made up of clusters of specialized skin cells called melanocytes which produce melanin. The pigment of each spot is determined by the number of cells clustered and the amount of melanin produced. While most moles are the result of genetics, sun exposure and sunburns can lead to the formation of more moles.

Most moles and freckles are considered harmless. However, atypical moles occur in around 10% of the population and some of these can be more serious. It is important to note if your mole changes shape, has irregular edges, grows, or bleeds. Atypical moles should be reviewed by a trained professional, such as a dermatologist, and a biopsy may be taken to check the mole.
