345 Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Dr.Althea is the best-performing 345 brand in July 2026, moving 100,000 units across 6 ASINs for 55.9% of Top 10 volume. ANUA follows with 70,000 units (39.1%), ahead of Beauty of Joseon on 6,000 units (3.4%).

With 4 brands splitting the Top 10 and 98.3% 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 $23.00 to $29.68, 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, 2 ASINs forced its way in: B07PK2P2XB booked 4K units at $27.00, with ▲ 566.7% MoM change. On the growth side, B0DNQC2D85 leads positive momentum with ▲ 33.3% MoM growth on 400 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
