	rdfs:comment """Age spots (also known as liver spot, solar lentigo, &quot;lentigo senilis&quot;,&quot;old age spot&quot;, &quot;senile freckle&quot;) are . They range in color from light brown to red or black and are located in areas most often exposed to the sun, particularly the hands, face, shoulders, arms and forehead, and the scalp if bald.
The spots were once called liver spots as they were incorrectly believed to be caused by liver problems, but they are physiologically unrelated to the liver, save for a similar color. They form after years of sun exposure.
In the overwhelming majority of cases, age spots pose no threat and require no treatment, though they occasionally have been known to obscure the detection of skin cancer. However, despite being a benign condition, age spots are sometimes considered unsightly and some people choose to have them removed. This can be done by electrosurgery, laser treatment, cryotherapy, or the use of depigmentation agents, such as hydroquinone,  tretinoin, topical cysteamine, azelaic acid, or alpha hydroxy acids.
