1. Before use: Be sure to ensure that the pores are completely open after the hot bath or sweating, keeping the face moist.
2, use: slowly move the product back and forth on the skin, do not stay in the same place for too long, so as not to damage the skin. It can absorb oil, whiteheads, acne and lighter blackheads. If the blackhead is deeper, it is best to use it with the blackhead export solution! It doesn't matter if you can't suck it at once. Don't use it for too long. Use it for a while, for a week or two. The deep blackhead will come out and will not leave scars.
3, after use, you can use some toner to tighten the water or cold water to shrink the pores and then do the follow-up maintenance. It is recommended to look at the manual again.
