Lash Serum Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Grande Cosmetics is the best-performing lash serum brand in July 2026, moving 39,000 units across 2 ASINs for 25.7% of Top 10 volume. The Ordinary follows with 30,000 units (19.7%), ahead of BABE ORIGINAL on 30,000 units (19.7%).

With 8 brands splitting the Top 10 and 65.1% 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 $14.90 to $52.00, 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, one ASIN forced its way in: B07NDN3R9P booked 8K units at $22.49, with ▼ 11.1% MoM change. On the growth side, B0GP6MHRGT leads positive momentum with ▲ 100.0% MoM growth on 1K units, with B0DPZPSZCW close behind at ▲ 50.0% MoM on 900 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
