Age spots, also known as “age pigmentation”, are commonly called “life spots”. With ageing, a large amount of unsaturated fatty acids in the body are oxidized by free radicals to generate lipofuscin, coupled with the low lysosomal function of the aging cells, the lipofuscin is not enough to be eliminated and the pigmentation patches are formed. Age spots are a kind of age-related changes of the skin. It is commonly found in sun-exposed areas of elderly men. Clinically, it is gray-brown or brown or gray-white flat and thin plaque, slightly higher than the surface, green bean to soybean size, irregular shape, sometimes can be fused into small pieces. Generally asymptomatic, sometimes slightly itchy. Age spots show mild hyperkeratosis on histopathology, and may have punctate keratosis. The epidermis is mildly hyperplastic and hypertrophic, and the dermis is often mildly basophilic. Age spots are generally non-inflammatory and may have a few lymphomonocytic infiltrates. For the appearance of facial discoloration, you need to ask the doctor for a face-to-face consultation.
