St Tropez Self Tanner Mousse Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Beauty by Earth is the best-performing st tropez self tanner mousse brand in July 2026, moving 40,000 units across 1 ASIN for 32.5% of Top 10 volume. Jergens follows with 20,000 units (16.3%), ahead of St.Tropez on 16,000 units (13.0%).

With 8 brands splitting the Top 10 and 61.8% 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 $10.47 to $36.05, 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: B00TBGQ4G8 booked 7K units at $27.00, with ▼ 12.5% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
