Emulsion You can use the ice cream in the noodle shop to replenish water and control oil, and apply it on your face, which is cool and cheap.
If you want to deal with blackheads, you can use Gamelot Blackhead Derivative and Pore Shrinking Essence, which are inexpensive and can last for a long time. I bought it online.
Hehe, I hope these are helpful to you.
