With the advancement of technology, people's quality of life has gradually improved. In addition to enriching their own internal knowledge and improving their cultivation, most of them have begun to enhance their external beauty. Therefore, medical beauty has also received more attention. Among them, the Pulse Pulsed Light (IPL) treatment has The treatment is mild and the time is short, so it is very popular among consumers.

Pulsed light waves themselves cover the usual laser wavelengths and can adjust their wavelength or energy to different skin conditions to improve different skin problems (eg, dark spots, fine lines, apple face, large pores, slight distiller's grains, Skin aging, rough and other issues). Even the general removal or removal of hair, the effect is good, and better than the traditional laser treatment.

At present, in the actual pulse light wave treatment operation, a common method is that the doctor directly operates the pulse light wave device according to the standard illumination parameter provided by the pulse light wave device manufacturer, or a doctor can visually examine the characteristic skin on the skin (for example, capillary Vasodilation, hemangioma, varicose veins, freckles, age spots, black sputum and/or hair), and after illuminating the characteristic skin with a pulsed light wave device, revisit the current condition of the characteristic skin to determine whether to increase or decrease the pulsed light wave device Irradiation intensity. However, this type of treatment is performed by a physician to visually examine the current changes in the characteristic skin and to make a comprehensive judgment based on the experience accumulated by the physician.
