Me Line Spot have been created to treat pigmentary lesions such as solar, actinic or senile lentigo which consists of a brown/black spot that can present either homogeneous or heterogeneous pigmentation. These types of lesions are induced by natural or artificial ultraviolet light. The lentigo generally has a flat or slightly depressed surface but occasionally they can present a wrinkled surface normally surrounded by normal-appearance skin. Over time, they can increase in size and number and even converse together forming a bigger patch. One particularity of the solar lentigo is that when observing it with epiluminescence microscopy we see that the pigmented area is cross-linked.
Generally, these types of lesions appear in skin phototypes I-III, usually in face, forearm, back of the hands and upper torso. It is very important to establish the differential diagnosis between ephelides (freckles), seborrheic keratosis and lentigo maligna.
