It's said that you can rub it right out after rubbing, but this varies from person to person. I couldn't rub it out, so I used an acne needle and scraped the blackheads out.
Then you can wash your face with water, but you can also wash your face with facial cleanser. I was able to wash my face with facial cleanser before I used the oil to rub it in, so I was able to wash my face with water directly.
And some of my friends have used them as if they were average.
