Oil pulling for face

I read somewhere recently about someone's experience with oil pulling for the face and I decided to try that out for myself today. Oil pulling involves putting a facial oil on your face and gently massaging for at least 15 to 20 minutes. I used my dear klairs gentle black deep cleansing oil and massaged my face gently with it for about 15 minutes. At about the seven minute mark, I started to feel grit beneath my fingers. True enough, dirt was coming out from deep within my pores and probably some blackhead and whitehead mixed with other stuff. My skin only had products from my AM ROUTINE and I did not have any makeup on. After this experience, I can truly say oil pulling for my face works for me. It wouldn't be something that I would do very often, but I would try to keep to at least once a week if I have the time. Have you tried this before?
