Chronic sun exposure is a common cause of brown pigment patches and vascular dilation creating facial redness. Other causes include ethnicity, tanning beds and genetic predisposition. While laser therapy is used to treat red and brown, the settings are customized to allow the laser to target the exact layer of tissue and pigment color of the lesion. Cherry angiomas are small round red lesions generally found on the trunk of the body and are not the result of sun damage but purely genetic in nature. They are also very effectively erased with laser therapy.
