It's a simple and very affordable trick. Just buy a face brush, like the one shown in the image above. You can find a similar one in any drugstore, like Target or Ulta.
Just rub your face with the brush and the facial cleanser, like the Younique Awake Facial Cleanser in soft circular motions. If you do this in the shower, the steam will help the pores to open and unclog.
Finish this routine with Rose Water damped in a cotton pad, to sooth and close the pores.
