GRAPHIC: How doctors remove blackheads

Although blackheads can be unsightly, they don’t pose any health risk. Many people mistakenly believe they are a sign of a dirty skin, but this simply isn’t true.

“Blackheads are just an oxidised mix of oil and dead skin cells that are sitting in pores – the exposure to air is what causes them to oxidise and turn black. It’s not a sign that you’re dirty, so don’t cause more damage by being rough with your skin and scrubbing really hard,” Dr Rachel Nazarian, a dermatologist at Schweiger Dermatology Group in New York City told Allure.

While blackheads don’t pose any health risks, they can negatively affect your self-confidence. Fortunately it is possible to treat blackheads at home with over-the-counter products that contain benzoyl peroxide, retinoids or salicylic acid.

In extreme cases, however, you may need to take prescription antibiotics or visit your doctor who will do an extraction.

The extraction procedure is fairly simple and non invasive. Your doctor uses a comedone extractor to remove the build-up trapped under your skin.

WARNING: Graphic extractions ahead

Sometimes blackheads can become so large they need to be extracted by a doctor. And sometimes the doctor films these extractions.
