Roc Firming Serum Stick Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

medicube is the best-performing roc firming serum stick brand in July 2026, moving 130,000 units across 2 ASINs for 23.6% of Top 10 volume. MEDITHERAPY follows with 100,000 units (18.2%), ahead of celimax on 100,000 units (18.2%).

With 9 brands splitting the Top 10 and 60.0% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $17.00 to $20.85, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 2 ASINs forced its way in: B0GCC2JV65 booked 40K units at $21.80, with ▲ 33.3% MoM change. On the growth side, B0GR1VKPFD leads positive momentum with ▲ 1150.0% MoM growth on 10K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
