Lip Liner Sharpener Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

REVLON is the best-performing lip liner sharpener brand in July 2026, moving 25,000 units across 2 ASINs for 36.8% of Top 10 volume. e.l.f. follows with 20,000 units (29.4%), ahead of Wonderskin on 10,000 units (14.7%).

With 9 brands splitting the Top 10 and 80.9% 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 $2.00 to $9.99, 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: B003HG4GQI booked 2K units at $4.50, with ▲ 0.0% MoM change. On the growth side, B0GGY7BMF3 leads positive momentum with ▲ 300.0% MoM growth on 800 units, with B0D46ZV4ZT close behind at ▲ 300.0% MoM on 200 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
