Drdorisday is a creator with a presence on Instagram (347,775 followers), TikTok (12,400 followers), based in United States. Their content sits in the skincare & dermatology space. Their YouTube bio reads: "Derm. Scientist. Pro-aging advocate. Transforming how you age- inside and out NYU Langone | Co-Founder Rapalogix Health | Author × 4 | Radio Host". The full audience and engagement breakdown is below.
Drdorisday reaches an audience concentrated in United States primarily through YouTube, and is best activated via Instagram Reels and Stories, TikTok branded content. Their sponsorship history skews toward Longevity / Health, a clear signal of fit for brands in those categories. Demonstrated partners include Rapalogix Health. Engagement on YouTube runs around 2.5%, which points to an audience better suited to category-relevant, mid-funnel campaigns than to pure-reach buys. The channel's mix of Instagram Reels and Stories and TikTok branded content lets a sponsor choose between short awareness placements and longer, more detailed integrations. Because the audience follows beauty content rather than arriving through untargeted reach, sponsorships that match the channel's subject matter tend to convert more efficiently than broad placements. A consistent, on-topic posting focus gives sponsors a predictable, brand-safe environment, lowering placement risk compared with broad, general-interest channels. Campaigns here are best measured on qualified engagement and consideration within the niche rather than on raw impression volume. For United States-focused brands in Longevity / Health and related categories, Drdorisday offers a defined, creative-fit audience rather than broad, low-intent impressions.
