1. Before Use: Make sure that the pores are completely open after having a hot bath or place a warm towel on your face.
2. During Use: Please move it slowly along the skin. Do not stay in the same position for more than 3 seconds to avoid your skin being hurt. It can suck out fats, whiteheads, and relatively shallow blackheads. If the blackhead is relatively deep, it is best to use it together with derived lotion. It doesn't matter if your blackheads are too stubborn after your first attempt of suction. Over a period of time, a week or two, the blackheads that are deeper will be out eventually, and it will not leave any scars.
3. After Use: You can create a skincare routine by using a toner or cold water to shrink the pores. It is recommended to consult the manual.
