Sun In Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Sun Bum is the best-performing sun in brand in July 2026, moving 59,000 units across 6 ASINs for 59.6% of Top 10 volume. Neutrogena follows with 10,000 units (10.1%), ahead of THINK on 10,000 units (10.1%).

With 5 brands splitting the Top 10 and 79.8% 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 $15.06 to $16.50, 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. On the growth side, B079LC5BC3 leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B07WLQSX8F close behind at ▲ 28.6% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
