The best, most effective way [to remove a pimple] is to see your dermatologist for a cortisone injection, which will shrink a pimple down within 24 hours. If you are unable to get to a dermatologist in time or would prefer to stay away from a shot, then use a medicated sticker or a concealer that has salicylic acid in it (something that many brands like Neutrogena and Cover fx sell.)

As for all of the old wives’ tales you’ve heard that miraculously shrink zits, like diaper rash cream or toothpaste? Dr. Kim does not recommend them. “Toothpaste may temporarily dry out a pimple but can be harsh and irritating,” she said. “I’ve seen skin burns from application of oregano oil and apple cider vinegar.”
RealSelf contributor Dr. Eric Schweiger added in an interview, “Fight the urge to do bathroom surgery and don’t try and pop it yourself.”
Due to hormones and stress, it’s nearly impossible to stop all random breakouts before they happen. “My best advice is to use a consistent skin-care regimen everyday, even when you don’t have a breakout,” Kim said.
