A dermatologist has warned against a beauty trend that involves opening the skin’s pores to remove blackheads and “grits.”

In recent weeks many fans of the extraction method have taken to the SkincareAddiction feed on Reddit to share their personal results following trying the process to extract ‘grits’ from the skin’s surface.

Details of the extensive regime, which is supposed to completely remove all debris from pores, were first shared on the thread a year ago, and Refinery29 describe the process as follows:

“You use an oil cleanser, followed by a clay mask, then a second round of oil cleanser, using your fingers to massage vigorously this time around.”

But Dr Anjali Mahto, consultant dermatologist at the British Skin Foundation, told HuffPost UK she would strongly advise against trying this.

“This method of removing blackheads is a worrying new trend,” Mahto said.

“I can’t stress enough how important it is to seek advice from a qualified dermatologist when treating problem skin.

“Using this alternative method may lead to infection or scarring.”
