Which one of ion beam and fractional laser is better, its effect varies from person to person, so it is impossible to judge at present. Fractional laser is the application of fractional laser to uniformly make many tiny holes on the skin, and then cause a series of skin biochemical reactions to achieve the effect of skin tightening, skin rejuvenation, lightening of pigmentation and improvement of scarring. Ion beam is a plasma radio frequency technology similar to laser. Its principle of action is that plasma produces non-gasified micro-exfoliation on the skin surface, initiating the body’s repair and reconstruction function, and the color and texture of the regenerated epidermis will be closer to normal skin. It can be used for acne pits, depressed scars, rough skin, fine lines, large pores, skin laxity and other symptoms. Comparing the two, it is impossible to judge which one is better due to the differences in personal constitution, condition, and the degree of technology of the hospital. People with aesthetic needs are advised to go to a regular hospital and have a professional doctor judge which one is suitable for them.
