LASHILÉ BEAUTY - Bringing a declining brand back to growth on Amazon

Lashilé Beauty sells beauty supplements through a seller account on Amazon.fr: Good Hair, Good Skin, Good Sun, Good Night and slimming gummies. We took over its advertising account in late March 2026.

In 2025, the brand had cut its advertising to stay profitable, and lost visibility in search. In early 2026, sales were still falling: −15% in February and March 2026 versus the same months of 2025, just before we arrived.

Goal: return to growth without hurting profitability.

When we arrived, defence and conquest were mixed, and several campaigns were bidding on the same searches. We rebuilt the account product by product: each search is now targeted only once.

Budget then goes to the queries that sell, with a presence all day long.

Every monthly report sets the target ROAS and TACOS; the next one says whether they were met. What does not convert is cut, like the sun care gift sets in June, and its budget goes back to the best sellers.

April to September 2026, versus the same 6 months of 2025, before we arrived (Amazon.fr):

• Total revenue: €839,654 versus €726,131 (+16%)
• ROAS: 3.01 versus 2.67
• 6 months out of 6 up on the same month a year earlier

April 2026, our first month, versus April 2025: 37% less advertising budget and 16% more orders.
