How is the black nose formed?

The root cause of blackheads is caused by large pores, and the methods that can be adopted are:

Fill a clean bowl with half a bowl of water and put it in the freezer of the refrigerator. Wash your face as usual every morning.

Take the frozen ice out of the refrigerator and add some water to it. Pour ice water on the towel and gently wipe your face with a cold towel.

After washing your face, use a black mysterious quick-freezing film on your blackheads.

Put the remaining ice back in the refrigerator and use it the next day. Be careful not to wash your face with cold water at night and go to bed early.
