Very good, put a cotton pad on your nose for 8 minutes, and you will see that the blackheads float obviously.
The one with a shiny nose, in addition to the effect, the biggest advantage of this one is gentleness. I tested it with a PH test paper.
It is weakly acidic. I have used several other porcelain muscles, all of which are super-stimulating with strong acid, so this one in Ji Hua Village is very good.
