Across Europe's ten largest online beauty markets, marketplaces now hold up to 34% of category sales. And that share grew by one percentage point versus the prior year. In the UK, TikTok Shop is already the second-largest online beauty merchant. In France, 30% of Amazon's new beauty customers came directly from Sephora, Nocibé, and Marionnaud. In Italy, 42% of Amazon beauty buyers shop nowhere else online.
These are not early warning signs. They are structural changes already in place. The brands that act now with clear channel roles, pricing discipline, and a direct customer data strategy, will be in a better position than those waiting to see how the market develops.
Let’s begin with some facts:
The France data is the clearest example of how this works. NIQ tracked where Amazon's new beauty customers came from: 18% were new to online beauty altogether (genuine market growth). 52% were returning Amazon shoppers. The remaining 30% switched from established specialist retailers like Sephora, Nocibé, Marionnaud.
This is not category expansion. It is a direct transfer of demand. And it is measurable: the switching matrix shows exactly which retailers are losing and how much. Sephora lost approximately 5 percentage points of switcher share. For brand manufacturers who rely on Sephora as their main online channel, this matters, their customers are migrating to Amazon, and the brand has no visibility into that journey and no CRM relationship on the other side.
30% of Amazon's new French beauty customers switched from named specialists. This is a direct share transfer, not category growth.
The exclusivity data adds further urgency. In Italy, 42% of Amazon beauty buyers are exclusive to the platform. They do not cross-shop. A brand with no Amazon presence cannot reach nearly half of Italy's online beauty buyers through any other channel. The implication is simple: a 'no marketplace' strategy is a 'smaller addressable market' strategy.
At 9.8% of online beauty value in the UK, TikTok Shop is no longer an experiment. It is the second-largest online beauty merchant in the market. Brands without a deliberate TikTok Shop strategy are already absent from a channel that holds nearly 10% of category sales.
What makes this more significant is the buyer profile. NIQ's UK panel data shows that TikTok Shop beauty buyers spent £80 more and placed 4.1 more orders than the average online beauty buyer. This is not a discount-driven audience. It is a high-value, high-frequency cohort — the kind of customer most loyalty programmes are designed to attract.
TikTok Shop beauty buyers in the UK placed 4.1 more orders and spent £80 more than the average online beauty buyer. This is not a bargain-hunter segment.
Social commerce requires the same operational discipline as any marketplace: clear SKU selection, pricing that does not conflict with DTC or specialist retail, inventory planning for demand spikes driven by viral content, and service standards that protect brand reputation. Running a creator programme without managing the commerce layer is leaving both revenue and customer data on the table.
The most common strategic mistake is treating all channels as equivalent revenue sources and optimising each in isolation. This creates pricing conflicts, assortment overlap, and a race to the bottom on margins. Each channel needs a defined role.
Most weekly trading reviews track revenue by channel and blended ROAS. That is not enough to understand what is actually happening to customer ownership. The following metrics are the minimum needed to manage the platform war in real time:
Platform presence is necessary — the data makes that clear. But platforms are not safe custodians of customer relationships. The transaction happens on their infrastructure. The customer record belongs to them. The retargeting audience is theirs.
The counter-strategy is to use platform scale to build off-platform relationships that the platform cannot disintermediate. On DTC and specialist retail, loyalty programmes and CRM are the primary tools. On Amazon, insert-in-package incentives, product registration flows, and post-purchase sequences (where permitted) can move marketplace buyers into a direct relationship. Even a modest conversion rate is strategically valuable at marketplace scale.
On Amazon specifically, tools like Amazon Marketing Cloud (AMC) allow brands to measure buyer overlap between Amazon and DTC, model the true incrementality of retail media spend, and identify the exclusive Amazon buyers who are otherwise invisible to their customer database. This is data infrastructure, not just paid media.
Use platform scale to build off-platform customer relationships that the platform cannot control. Presence is necessary. Ownership requires deliberate investment.
Europe's online beauty market is growing and becoming more competitive at the same time. Marketplaces and social commerce are gaining share. Customer switching is real and measurable. The brands that will come out ahead are not those with the largest platform presence — they are the ones that use that presence to build a direct customer relationship that no platform can take away.
