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

Wonderskin is the best-performing lip liner stain brand in July 2026, moving 23,000 units across 3 ASINs for 29.5% of Top 10 volume. Sacheu follows with 17,000 units (21.8%), ahead of Laka on 10,000 units (12.8%).

With 7 brands splitting the Top 10 and 64.1% 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 $11.89 to $19.47, 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, 3 ASINs forced its way in: B0CN1D9C6Q booked 7K units at $14.40, with ▲ 40.0% MoM change.

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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
