The prevalence and nature of sponsored posts on Instagram by dermatologists have been well characterized within the literature [1]. Dermatologists use social media to provide education and recommend products; however, well-intended products and misinformation may be convoluted by financial or personal interests, potentially risking patient welfare. With the growing use of social media, we aimed to characterize the prevalence of sponsored posts by dermatologists on TikTok (ByteDance Ltd), a popular and rapidly growing video-sharing platform [2,3].

The following keywords were used to search for dermatologists’ profiles on TikTok: dermatology, dermatologist, board-certified dermatologist, and doctor. Exclusion criteria included profiles that were private or those without first or last name, degree, and specialty. Of the profiles included, the following data were collected for each profile: username, gender, training level (attending, resident, fellow), follower count (as a proxy for engagement), total number of posts, number of self-reported sponsored posts, number of dermatology-relevant sponsored posts, and category of sponsored posts (Table 1).

A total of 94 profiles were included; 67 (71.3%) belonged to female users and 27 (28.7%) belonged to male users. Attendings and residents/fellows accounted for 89.4% (n=84) and 10.6% (n=10), respectively. Of the 94 profiles, 38 (40.4%) had sponsored content, of which 32 (84.2%) were attending and 6 (15.8%) were trainee profiles. Among the 38 sponsored dermatologists, 34 (89.5%) had dermatology-relevant content. Residents/fellows had a greater median number of followers compared to attendings (28,650 vs 20,950). Sponsored dermatologists had a greater median number of followers than nonsponsored dermatologists (66,100 vs 1639) (Table 1). Sponsored dermatologists had significantly more followers even after subdividing by training level (P<.001 for attendings and P=.02 for residents/fellows). Table 2 displays the Spearman ρ and the corresponding P values for the number of followers, sponsored posts, and number of dermatologist sponsors.

Our study identified that less than half of the surveyed dermatologists on TikTok had sponsored posts. Dermatologists that had sponsored content had a higher number of followers, with a correlation between increased number of sponsored posts and number of followers. This highlights that product advertisement reaches larger audiences than medical education. Companies often seek highly followed “influencers” to maximize brand marketing [1,4].

Dermatologists with large followings and sponsored content have stewardship to educate their viewers and not only advertise. Dermatologists on TikTok can educate a wide audience about skin, nail, and hair health, and should do so mindfully. If patient welfare is prioritized above personal interests from sponsorship, dermatologists can have a profoundly positive impact on their TikTok audience. To prevent such biases, sponsored dermatologists must remain transparent on social media and disclose conflicts of interest clearly.

Social media is an integral part of society and influences the health care provider–patient dynamic, the dissemination of medical knowledge, and the delivery of care [5]. Dermatologists have leveraged TikTok to connect and educate the public and promote brands and best practices. The wide reach of social media augments the negative impact of promoting non–evidence-based products, sharing inaccurate information, and making wrongful claims. Dermatologists must be aware that the ethical standards that apply to patient care also apply to social media so that patient well-being is prioritized.
