What is semi-permanent lip drift?

Semi-permanent lip bleaching is to implant natural pigment into the skin surface, which is generally non-toxic and harmless, will not be dissolved by water, and has a natural effect. But generally speaking, the lip color will gradually fade after about 3 -5 years, and lip color bleachers can recolor according to their own suitable color, so that the same effect can be achieved when they just bleach their lips.
