Age spots are not only for the elderly. It is a benign epidermal proliferative tumor that is more common in the elderly and may be related to factors such as sun exposure and chronic inflammatory stimulation. Due to long-term sun exposure, chronic inflammation and other factors, the skin cell metabolism is abnormal and keratinized cells cannot be shed normally, while the pigment particles inside the cells cannot be discharged from the body in time. Although the occurrence of this disease has a certain relationship with skin aging, it does not mean that only the elderly will have age spots, such as people who do not pay attention to skin cleaning and skin care for a long time, as well as workers who are exposed to the wind and sun for a long time, can develop the disease. At the same time, the occurrence of seborrheic keratosis has a certain genetic susceptibility, if there is a father with seborrheic keratosis in the family, the offspring is also prone to occur, and the age of occurrence is not limited to the elderly over 60 years old, but also the middle-aged and young people can develop the disease, so it further indicates that not only the elderly can develop the disease. Seborrheic keratosis lesions are usually found on the face, back of the hands, chest and back, and are single or multiple yellowish or light brown flat papules or plaques slightly above the skin surface. If it affects aesthetics, it can be treated by freezing, laser or electrocautery to remove local lesions and restore normal skin appearance.
