Solar lentigo (synonyms: lentigo actinica, senile lentigo, liver spots)  are flat brown-black spots that usually occur in sun-exposed areas of the body. They are also called age spots. They are unrelated to the liver or liver function.

 

The brownish macule occurring usually as numerous lesions on chronically sun-damaged skin. Solar lentigo may be regarded as the precursor lesion of the reticulated type of seborrheic keratosis, because of the frequent association of these two pigmented skin lesions on clinical and histopathologic grounds

Prevention

Protect your skin from the sun by taking the following precautions:

  • Wear protective clothing such as hats, long-sleeved shirts, long skirts, or pants.
  • Use sunglasses to protect the eyes.
  • Sunlight is most intense at midday, so try to avoid exposure during these hours.
  • Use high quality sunscreens, preferably with SPF (sun protection factor) ratings of at least 15. Apply sunscreen at least a half hour before exposure, and reapply frequently. Use sunscreen in the winter, too.

Treatment with Laser

Lasers are most effective in treating epidermal pigmented lesions (eg, lentigines, ephelides).

 

Variable responses can be expected in café au lait macules, Becker nevi, nevus spilus, and melasma. Nevus of Ota is unique in that near-total clearance is often seen after laser treatment.
