MEDI-PEEL ended Derma Factory's run at Coupang's skincare #1

Coupang is Korea's everything store. We read its skincare best-seller list every day and report only the days we can verify.

A long run

Fact. Derma Factory had Coupang's skincare #1 on every captured day from Oct 10 to Oct 26 — fifteen in a row. Fourteen of those were its Niacinamide 20% Serum; on Oct 23 it was the brand's Retinal 300ppm Cream.

The handover

Fact. On Oct 27 MEDI-PEEL's Melanon X Cream was #1, followed by The Ordinary's Niacinamide 10% + Zinc 1% Serum and AESTURA's Atobarrier 365 Cream Plus. Derma Factory's best place that day was #8, with the serum sold as a two-pack; the single 30ml serum that had led the chart was not in that day's top 100. Observation. MEDI-PEEL's cream had been #2 on eight of the fifteen days of the run. Inference. On a daily chart a long run can end in a day, and a listing leaving the list is not the same as a product losing buyers — one day is too short to say which.
