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

TL;DR

medicube US Store staged an overwhelming category takeover across skincare on TikTok Shop in the United States for October 2026, capturing four of the top five ranks and anchoring a commanding 67.5% top-ten concentration. Lone challenger d'Alba Piedmont broke the monopoly at rank two with its White Truffle spray, while dark horse formulas from Gopure and epais clung to ranks eight and ten. This monopolistic clustering means emerging beauty labels must rethink creator scale, as medicube US Store's affiliate web leaves almost no algorithmic surface area for unestablished brands. With category GMV flat at +0.0%, growth was zero-sum, turning October 2026 into a direct brand displacement battle.
