Top 20 Skincare Best Sellers on TikTok Shop United States — August 2026

TL;DR

K-beauty heavyweight medicube US Store effectively locked down the skincare category on TikTok Shop in the United States for August 2026, capturing six of the top ten slots even as its flagship balm saw GMV retreat by -55.9%. This means viral skincare leadership is now insulated by catalog depth rather than single-SKU dependence. Behind the leader, challenger Dr.Melaxin mounted steady pressure at rank 3 with +10.6% GMV growth, while dark horse Tarte Cosmetics carved out rank 5 with its sun-care hybrid. Across ranks 6 through 10, Dr.Melaxin and medicube US Store split the remaining volume entirely. With total category GMV reaching $89.7M, top-tier incumbents left virtually no oxygen for unestablished newcomers.
