　　1. What is its principle?

　　Answer: Three aspects are mainly involved.

　　(1) Light modulation function

　　(2) Light stimulation

　　(3) Selectivity of light

　　Light modulation is the use of LED irradiation to regulate cell activity and achieve the effect of skin rejuvenation. This is different from the photothermal effect of laser beauty. The photothermal effect is that when the tissue absorbs the photon energy, it can be converted into heat in most cases, resulting in These tissues that absorb photon energy are denatured, even solidified or necrotic. If photons with huge energy are absorbed in a short period of time, it may cause the physical disintegration of tissues. This is the principle of laser tattoo removal. Does it hurt? The light-toning effect is non-heating, or slightly hot, far from achieving the effect of light-heating that relies on temperature to degenerate and coagulate or necrotize tissues, thereby moderately damaging and stimulating skin regeneration.

　　All kinds of red light, yellow light, and infrared light are all made of beauty by this effect. In addition, not only LED light can be used, but laser or strong light also has a certain light adjustment effect. It's just that their photothermal effect is the mainstream and the main goal that people pursue. Under the cover of the powerful photothermal effect, the light-tuning effect is less noticeable, and it is not very much mentioned.

　　What is light stimulation? In clinical medicine, certain low-energy light can accelerate wound healing. What is the mechanism of this effect? No one knows yet. It is speculated that it is achieved by improving blood circulation or stimulating collagen synthesis. Anyway, it is currently called light stimulation.

　　What is light selectivity? Professionally called selective photothermal effect. In layman's terms, the absorption of light by the various tissues on our face is not irresistible. Only those that meet its appetite can absorb it in large mouths. It is also only when enough light is absorbed to produce some functions, such as absorbing enough light to have enough heat, to dissolve melanin or hair follicles (freckle whitening or hair removal), to close capillaries (to remove red blood streaks), and so on.
