Wonderskin Eyeliner Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Wonderskin is the best-performing wonderskin eyeliner brand in July 2026, moving 60,000 units across 5 ASINs for 37.5% of Top 10 volume. REVLON follows with 40,000 units (25.0%), ahead of NYX PROFESSIONAL MAKEUP on 30,000 units (18.8%).

With 5 brands splitting the Top 10 and 81.3% 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 $9.03 to $17.76, 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: B0D83XSZGK booked 10K units at $9.99, with ▲ 42.9% MoM change. On the growth side, B0D1KR927V leads positive momentum with ▲ 400.0% MoM growth on 5K units, with B0CN1D84XJ close behind at ▲ 50.0% MoM 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
