Dermatologists take to TikTok to share their own ‘hacks’


 

A young woman is having her lip swabbed with an unknown substance, smiling, on the TikTok video. Seconds later, another young woman, wearing gloves, pushes a hyaluron pen against the first woman’s lips, who, in the next cut, is smiling, happy. “My first syringe down and already 1,000x more confident,” the caption reads.

That video is one of thousands showing hyaluron pen use on TikTok. The pens are sold online and are unapproved – which led to a Food and Drug Administration warning in October 2021 that use could cause bleeding, infection, blood vessel occlusion that could result in blindness or stroke, allergic reactions, and other injuries.

The warning has not stopped many TikTokkers, who also use the medium to promote all sorts of skin and aesthetic products and procedures, a large number unproven, unapproved, or ill advised. As TikTok has become one of the most widely used social media platforms, millions of mostly teenagers regularly log on for skin care advice, which, more often than not, comes from “skinfluencers,” aestheticians, and other laypeople, not board-certified dermatologists.

The suggested “hacks” can be harmless or ineffective, but they also can be misleading, fraudulent, or even dangerous.

Skinfluencers take the lead

TikTok has a reported 1 billion monthly users. Two-thirds are aged 10-29 years, according to data reported in February 2021 in the Journal of the American Academy of Dermatology by David X. Zheng, BA, and colleagues at Case Western Reserve University, Cleveland, and the department of dermatology, Johns Hopkins University, Baltimore.

Visitors consume information in video bits that run from 15 seconds to up to 3 minutes and can follow their favorite TikTokkers, browse for people or hashtags with a search function, or click on content recommended by the platform, which uses algorithms based on the user’s viewing habits to determine what might be of interest.

Some of the biggest “skinfluencers” have millions of followers: Hyram Yarbro, (@skincarebyhyram) for instance, has 6.6 million followers and his own line of skin care products at Sephora. Mr. Yarbro is seen as a no-nonsense debunker of skin care myths, as is British influencer James Welsh, who has 124,000 followers.

“The reason why people trust your average influencer person who’s not a doctor is because they’re relatable,” said Muneeb Shah, MD, a dermatology resident at Atlantic Dermatology in Wilmington, N.C. – known to his 11.4 million TikTok followers as @dermdoctor.

To Sandra Lee, MD, the popularity of nonprofessionals is easy to explain. “You have to think about the fact that a lot of people can’t see dermatologists – they don’t have the money, they don’t have the time to travel there, they don’t have health insurance, or they’re scared of doctors, so they’re willing to try to find an answer, and one of the easiest ways, one of the more entertaining ways to get information, is on social media.”

Dr. Lee is in private practice in Upland, Calif., but is better known as “Dr. Pimple Popper,” through her television show of the same name and her social media accounts, including on TikTok, where she has 14.4 million followers after having started in 2020.

“We’re all looking for that no-down-time, no-expense, no-lines, no-wrinkles, stay-young-forever magic bullet,” said Dr. Lee.

Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, agreed that people are looking for a quick fix. They don’t want to wait 12 weeks for an acne medication or 16 weeks for a biologic to work. “They want something simple, easy, do-it-yourself,” and “natural,” he said.

Laypeople are still the dominant producers – and have the most views – of dermatology content.

Morgan Nguyen, BA, at Northwestern University, Chicago, and colleagues looked at hashtags for the top 10 dermatologic diagnoses and procedures and analyzed the content of the first 40 TikTok videos in each category. About half the videos were produced by an individual, and 39% by a health care provider, according to the study, published in the International Journal of Women’s Dermatology. About 40% of the videos were educational, focusing on skin care, procedures, and disease treatment.

Viewership was highest for videos by laypeople, followed by those produced by business or industry accounts. Those produced by health care providers received only 18% of the views.

The most popular videos were about dermatologic diagnoses, with 2.5 billion views, followed by dermatologic procedures, with 708 million views.

Ms. Nguyen noted in the study that the most liked and most viewed posts were related to #skincare but that board-certified dermatologists produced only 2.5% of the #skincare videos.
