A lentigo (lentigines for plural) is a small brown pigmented skin macule that’s caused by an increased number of melonocytes for no apparent reason. This skin condition is more common among Caucasians, especially those with fair skin. Lentigines tend to be darker than freckles and can appear anywhere at any age, even on your lips and gums.
Lentigo skin lesions that are caused by sun exposure or ultraviolet light are called solar lentigines, aka liver spots. Solar lentigines can appear anywhere your skin receives sun, frequently your face and hands. And the solar type lentigo usually occurs on aging skin.
No treatment is necessary for a lentigo, lentigines nor solar lentigines. However, treatment for cosmetic purposes is available, including:
- cryotherapy
- laser treatment
- intense pulsed light
- skin bleaching lotions, creams
Although solar lentigines are benign, they do indicate excessive sun exposure, a risk factor for skin cancer. And if you have a lentigo that makes skin cancer diagnosis difficult, particularly melanoma, then surgical removal may be recommended.
One of the best ways to prevent lentigines and preserve skin health is to use sunscreen during prolonged sojourns out in the sun. And avoid the tanning bed solution for golden skin color.
