Derm Shares The Popular Anti-Aging Tool That Is ‘The Worst Thing’ For Your Face: ‘Reintroducing Bacteria Into Your Face’
March 19, 2025 by Marissa Matozzo
Facial cleansing brushes (made popular by brands like Clarisonic) gained popularity in the 2010s, but also received criticism for possibly harming the skin’s protective barrier and triggering irritation or breakouts due to over-exfoliation and misuse.
Some users on social media reported that despite the advanced sonic technology, the brushes caused excessive exfoliation, removing essential oils and disrupting the skin’s protective layer.
This disruption often resulted in dryness, irritation, and could worsen acne or provoke new breakouts. People with sensitive skin might find it difficult to tolerate regular use of these brushes, experiencing discomfort or negative reactions.
In an informative TikTok video, dermatologist and skincare specialist Dr. Shereene Idriss thoroughly explained why this tool should be avoided for achieving healthier skin after 40. She highlighted that using such brushes can unintentionally transfer bacteria and grime back onto your face during cleansing.
At the beginning of her above video (titled “Skincare Tools You Should Not Waste Your Money On!”), Idriss stopped by a drugstore’s skincare department and pointed to a Clarisonic knockoff facial cleansing brush. She then said, “This is what I’m looking at. For 40 bucks, please don’t waste your money.”
The dermatologist continued, “There was a company called Clarisonic that went out of business of a few years ago that basically just did this. You don’t need this. This is, like, one of the worst things you could do for your face.”
Clarisonic, once known for its skincare devices featuring an oscillating brush, was available in specialty beauty stores. The company ended its operations and the brand was discontinued as of September 30, 2020.
Idriss added that “more often than not, people never wash the heads” of these brushes. This, she noted, means that “they’re constantly reintroducing bacteria and crud into their face.”
