Theory & function:Picosecond is a unit of time, 1 second = 1 trillion picoseconds, (1 second = 1000 Milliseconds, 1 millisecond = 1000 microseconds, 1 microsecond = 1000 nanoseconds, 1 nanosecond = 1000 picoseconds); therefore, the speed is fast, the same effect acts on the skin for a short time, and no damage.

Light selective absorption blasting chromophore:Light acts on the skin and light energy is converted into heat. The melanin mass quickly absorbs a lot of heat. The instantaneous heating blasting decomposes the melanin group into a small number of melanin small particles, and the shallow pigment small particles immediately extract the epidermis crust and disappear with the scab. The deep pigment particles are swallowed by human macrophages and will be excreted with the lymphatic system.

Does not damage normal skin:Normal surrounding skin tissue, no damage is formed because no pigment does not absorb laser light of fixed wavelength
