As the skin ages, natural aging and photoaging will inevitably occur, resulting in skin laxity, increased wrinkles, enlarged pores, increased pigmentation, capillary dilation and abnormal redundancy. Age spots, also known as seborrheic keratosis, senile warts and basal cell papilloma, are the most common benign skin tumors in middle and old age, but many young men and women can also be involved, without gender differences. The cause of this disease is still unclear, there is a clear genetic predisposition, or related to long-term sun exposure. The course of the disease is slow and does not heal over the years. If it suddenly increases, it may be the skin manifestation of malignant tumors, especially gastrointestinal tumors. The rash usually occurs on the face, especially the temporal area, followed by the back of the hands, trunk and extremities, but can occur anywhere on the body surface. Early damage is small, flat, well-defined patches with smooth or slightly rough surface, light yellow-brown or brownish. Later, the damage gradually increases in size, the surface becomes more elevated and papilloma-like, and a thick, oily crust may form. Pigmentation can be very significant. The color of the old damage varies greatly, and can be healthy skin color or light teal or even dark brown, or even black, and the number is variable. The disease generally has no conscious symptoms, and occasionally may be pruritic. The disease is rarely malignant, but obviously affects the beauty of the face, once it appears, it seems to make people feel that they have entered old age. In fact, otherwise, with the progress of society, the improvement of medical conditions, and the improvement of people’s health awareness, the survival period of health is getting longer and longer, and the health condition of the body seems to be disproportionate to the condition of the facial skin. Therefore, it is necessary to get rid of the aging spots on the face so that you can feel still healthy, young and energetic. The treatment of this disease is not difficult, and the main methods are CO2 laser treatment, cryotherapy, photodynamic therapy, etc.
