A solar lentigo (actinic lentigo, senile lentigo, sun spots, age spot) is a pigment spot on the skin associated with aging and exposure to ultraviolet radiation from the sun. Colloquially this spot is called “liver spot” or “sunspot” or “age spot” (senile lentigo). However, these spots are not associated with liver problems.
The main cause of the appearance of these pigment spots on the skin is the sun exposure of unprotected skin, both by occasional sunburn, as well as chronic exposure.
These are spots on the skin less than one centimeter in diameter that vary in color, from light brown to red or even black, and are located in the areas most sun exposed, particularly hands, face, shoulders, arms and forehead, even the head if it is bald. The most frequent pigment spots are located on the face.
It is important to differentiate a solar or senile lentigo from a maligant melanoma lentigo type before doing a treatment to remove this pigment spot.
