[0002] A skin treatment instrument is a medical device that uses technologies such as light with a specific wavelength, radio frequency, microcurrent, plasma, etc. to improve skin problems. Plasma skin treatment is a non-invasive skin treatment method that uses the plasma technology of the treatment instrument to improve skin problems. Plasma is the fourth state of matter, composed of active components such as ions, electrons, and free radicals. In plasma treatment, plasma is generated by a skin treatment instrument and applied to the skin surface to stimulate the production of collagen, improve blood and oxygen circulation, improve skin texture, reduce wrinkles and age spots, etc. Plasma treatment instruments can be used to treat various skin problems, such as acne scars, age spots, wrinkles, skin laxity, etc., and they can also be used to stimulate hair growth and improve the overall health of the skin.

[0003] Currently, for the operating handles of skin treatment instruments on the market that generate plasma by ionizing nitrogen, oxygen, etc. in the air with high-voltage electrodes, there are generally problems such as easy loosening and displacement in the installation of the circuit board and the high-voltage electrode. The high-voltage electrode cannot always be kept at the center point, and it is impossible to ensure that the high-voltage electrode discharges evenly and vertically to generate an ionization reaction. There is also a risk that the high-voltage electrode may break down the surrounding insulators during the discharge process, causing damage. Summary of the Invention
