A dermatologist has warned Australians to be careful with the latest skincare routine going viral on TikTok.

Tia Zakher has been recognized for sparking interest in the ‘caveman method’, a skincare routine that involves eliminating all skincare products in an effort to address persistent skin issues.

Her TikTok videos on this method have garnered over 50 million views in just the past week, and global Google searches for ‘caveman method’ surged on April 27, merely two days after she posted one of her initial videos.

While it might seem like a contemporary social media trend, the caveman method—or some variation of it—has existed for years, and dermatologists sometimes recommend it to patients.

“It’s quite common for us in dermatology to see people who have a problem with the products they’re putting on their face,” he said.

“So the best thing is stop everything, and that’s pretty much the caveman routine.”

Common skincare concerns that can be traced back to specific products or ingredients include contact dermatitis, allergic reactions, redness, inflammation, sensitivity, flares in acne or rosacea, and damage to the skin barrier.

Cutting out all skincare products, as in the caveman method, then reintroducing them one by one may help patients identify what is causing their skin concerns.

However, Freeman warned that this is only intended as a short-term routine to identify and address skin concerns that may be linked to certain skincare products.

”The last thing that I would like to suggest is that this is a good routine to use forever,” he said.

“In my mind, dermatologically speaking, it should only be used temporarily.”

Patients should also continue using SPF while following the routine, as skipping it increases the risk of sun damage and melanoma.

Freeman cautioned Australians against taking specific skincare advice from influencers, as what works for one person will not be suitable for everyone.

He suggested speaking to a dermatologist or GP about skin concerns, or seeking information online or using AI tools before starting a new skin routine.

Zakher has not responded to questions from 9news.com.au about her skincare routine, if she has consulted with a dermatologist, or the online reaction.
