It takes 200-300 yuan to soak once, and it must be done for a long time, because things such as oil are constantly secreted. I used to do it when I was working in a beauty salon. Later, I changed my job and thought it was really too expensive to go to a beauty salon, so I bought one myself. I chopped up the Velvet Bubble endorsed by Jelly Lin, because this is a beauty salon route, and the suction of the two pumps is relatively large, and the effect is similar. That hundred dollars is for home use, actually.
