Using a pore vacuum is actually quite simple. Ideally, you want to start by first preparing your skin by cleaning it with warm water or a damp hot towel. This helps open up your pores, making it easy for the machine to suck the blackheads. Once you’ve done this, turn on the machine and set it on the lowest setting, then gently move the suction head over the spots with blackheads and let it do its job. You can adjust the settings depending on the amount of suction you need. Also, don’t stay on one spot for more than 5 seconds; it might lead to bruising.
