I heard about that the oil cleanser can remove blackheads which when I tried is true but I don't think you should keep massaging your face for 10-15 minutes here the steps I did
-Put a warm towel on the nose and chin area
-Pump the oil cleanser 4 times to avoid the friction of the hand
-Then emulsify, apply some water on your face while massaging the oil should look color white now
-Then use a foam cleanser then Moisturize
I use to do this for atleast one per week
Btw you can check Wishtrend video about this if your wanna learn more (the title is "How to remove Blackheads and not enlarge your pores" )
