【英语时差8,16】电针除痣（上）

From Botox to liposuction, people will go to great lengths to become beautiful. Some will even allow themselves to be electrocuted. As in electrolysis, the hair removal process involving mild doses of electrical current used to kill hair follicles. During electrolysis, a technician inserts a needle into a hair follicle and zaps it with electricity. Once zapped, the follicle won’t produce more hair. There are three types of electrolysis. The Galvanic Method uses a needle conducting DC current that triggers a chemical reaction in the hair follicle. The reaction produces sodium¹ hydroxide, or lye, which kills the follicle. The Thermolysis Method uses an AC current and causes water molecules² surrounding the follicle to vibrate, producing heat much like a microwave oven to kill the follicle. Combining the Galvanic and Thermolysis techniques, the Blend Method runs both AC and DC currents to kill the follicle more quickly.
