Ems (electrical Muscle stimulation) micro-current technology is a cosmetic method in which the action potential of the central nervous system during the contraction of muscles is controlled by using current to simulate the action potential of the central nervous system, so that the muscles are stimulated to contract and promote blood circulation, the yield of elastic fibers is increased, and the activity of the muscles is re-excited, thereby relaxing muscles tensed due to daily facial expression, and having remarkable effects of preventing facial muscles from atrophy and sagging, improving facial Muscle aging, and restoring facial skin elasticity. When the face is lifted and massaged, the key cap 213 is pressed, so that the key cap 213 presses the control key 235, and the three-in-one beauty instrument is adjusted to the EMS micro-current mode. At this time, the control circuit board 23 starts to control the current to flow to the first roller shaft head 11 and the second roller shaft head 12, before the first roller shaft head 11 and the second roller shaft head 12 contact with the skin, the current cannot be communicated because the first roller shaft head 11 and the second roller shaft head 12 are not electrically connected with each other, the control circuit board 23 monitors that the current is not circulated, and the three-in-one beauty instrument is in a standby state; when a user places the beauty head 1 on the surface of skin, the first roller shaft head 11 and the second roller shaft head 12 are simultaneously contacted with the skin, current can circulate, the control circuit board 23 monitors that the current can pass, and controls the three-in-one beauty instrument to be switched into a running state, the first roller shaft head 11 and the second roller shaft head 12 release the current to the skin to simulate the action potential of central nerve, so that the muscle of a contact part is contracted, and the drooping muscle of the face is lifted; when the fine position of face is massaged, because the position restriction, probably only first roller spindle nose 11 can contact with face's skin, place the finger this moment and put on the third roller spindle pole 133 of metal system, because human electrically conductive action, first roller spindle nose 11 and third roller spindle pole 133 can form a circulation again for trinity beauty instrument can be with monopole mode normal operating.

Ep (electroporation) is a cosmetic method that can promote absorption of skin care products. Skin care products contain a large number of macromolecules, which are normally not absorbed by skin cells through cell membranes, and thus the skin care effect that can be exerted by manually applying the skin care products to the skin surface is only about one percent. However, when the device is powered on, the cell membrane can not pass current, but can act as a capacitor, and an ion channel can be formed instead, so that macromolecular compounds can pass through the ion channel. The EP electroporation technology just utilizes the characteristic of cell membranes, and the beauty treatment head 1 is utilized to place cells under the stimulation of a specific electric field to form a temporary channel through which macromolecules can pass, so that macromolecular compounds which generate effects in the skin care product are promoted to permeate into skin cells, and the absorption rate of the skin care product can be improved by ten times. When skin care products are needed to be LED in, the key cap 213 is pressed, so that the key cap 213 presses the control key 235, the three-in-one beauty instrument is adjusted to the EP electroporation leading-in mode, and the corresponding mode can be displayed on the LED display screen 234. The main purpose of the EP electroporation mode is to introduce the active ingredients of the skin care product into the dermis of the skin in order to promote penetration of the cosmetic, in which mode the control circuit board 23 monitors whether the first roller shaft head 11 and the second roller shaft head 12 or the third roller shaft rod 133 of the cosmetic head 1 have been in contact with the skin through conduction, and if a cycle has been formed, it starts to control to precisely output a current with a voltage of 30-35V and a cycle number of 2200Hz-40000Hz to the skin of the cosmetic head 1, so that ion channels are temporarily formed on the cell membrane and the macromolecular compounds are introduced into the cells; when the beauty treatment head 1 stops contacting with the human body and can not form effective conductive circulation, the control circuit board 23 controls the power supply 22 to stop outputting current to the beauty treatment head 1, and enters a standby mode, and when the standby time exceeds the preset time, the control circuit board 23 can also control the three-in-one beauty treatment instrument to automatically shut down so as to save electric quantity.

Mp (mesoporation) needleless cosmetic technology is a cosmetic technology that combines electroporation and electroosmosis techniques. Firstly, an electroporation technology is utilized, and an electric shock hole which can be kept open within seconds or even minutes is formed on a lipid bilayer of skin cells through electric shock, so that hydrophilic molecules which cannot be absorbed by the cells in the skin care product can penetrate through the lipid bilayer of the cells to enter the cells; then, the electroosmosis technology is utilized to promote absorption of dispersed nutrient molecules in the skin care product, positive current is applied to the nutrient molecules of the positive electrode, and the nutrient molecules can be pushed into skin tissues due to mutual repulsion of charges with the same property, and neutral molecules can be driven to penetrate into the skin at the same time. When the needle-free beauty treatment is needed, the key cap 213 is pressed to control the three-in-one beauty instrument to be switched to the MP needle-free beauty treatment mode, the control circuit board 23 controls the beauty head 1 to apply electric shock to the skin firstly according to a preset program, so that the lipid bilayer of skin cells generates an electric shock hole, and then the cosmetic head is switched to a positive current release mode to push nutrient molecules in the skin care product to enter the dermis of the skin through the electric shock hole, so that the skin care process under the whole set of MP needle-free beauty treatment mode is completed.
