Ordinary Hyaluronic Acid Serum Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

The Ordinary is the best-performing ordinary hyaluronic acid serum brand in July 2026, moving 380,000 units across 5 ASINs for 55.1% of Top 10 volume. celimax follows with 100,000 units (14.5%), ahead of ANUA on 70,000 units (10.1%).

With 6 brands splitting the Top 10 and 79.7% 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 $9.06 to $22.00, 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: B0C3PCJ6SD booked 50K units at $6.70, with ▲ 0.0% MoM change. On the growth side, B08936CZHQ leads positive momentum with ▲ 900.0% MoM growth on 3K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
