Sun Bum Lip Balm Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Sun Bum is the best-performing sun bum lip balm brand in July 2026, moving 49,000 units across 4 ASINs for 35.5% of Top 10 volume. KAHI follows with 20,000 units (14.5%), ahead of Aquaphor on 20,000 units (14.5%).

With 7 brands splitting the Top 10 and 64.5% 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 $4.84 to $21.98, 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: B0163BMUFM booked 9K units at $9.98, with ▲ 12.5% MoM change. On the growth side, B07BHB99BY leads positive momentum with ▲ 150.0% MoM growth on 5K units, with B008SQSBJK close behind at ▲ 100.0% MoM on 20K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
