Top 20 Skincare Best Sellers on TikTok Shop United Kingdom — September 2026

TL;DR

A brutal category contraction failed to break the absolute duopoly dominating skincare on TikTok Shop in the United Kingdom during September 2026. While total category GMV dropped by -71.1%, plmakeupacademy and medicube UK tightened their grip on the market, sweeping all five top positions. plmakeupacademy captured first place propelled by a massive +326.2% sales explosion on its lead trio, while medicube UK mounted a multi-SKU defense across ranks two, four, and five. This means consumers are consolidating their spending around proven viral heroes and established clinical routines rather than trying newcomer products. Further down the board, challengers Dr.Leo-UK and The Ordinary Store UK carved out niches, but neither could dismantle the heavyweights holding court.
