Eucerin Skincare Ad Banned in UK for Misleading Age Claim

A skincare advertisement promoting a popular anti-ageing serum has been banned in the UK after regulators ruled that its claims were misleading and not backed by strong enough scientific evidence.

The advert for Eucerin Hyaluron-Filler Epigenetic Serum suggested that users could appear “up to five years younger” within just four weeks. However, the UK’s advertising watchdog, Advertising Standards Authority (ASA), found that the claim lacked sufficient proof.

Why the Ad Was Banned

The promotion, which appeared at Balham Underground Station in November 2025, featured a close-up image of a woman’s face with highlighted skin areas. It referenced results from a study involving 160 participants to support its anti-ageing promise.

But after reviewing the evidence, the ASA concluded that the data did not meet the required standards to justify such a measurable claim.

According to the regulator, statements like “look up to five years younger” require objective and verifiable scientific backing. In this case, the evidence submitted failed to meet that threshold.

Concerns Over Supporting Studies

The serum’s manufacturer, Beiersdorf, provided several studies and a peer-reviewed paper to defend the claim. However, the ASA raised multiple concerns about how the research was conducted.

One key study involved participants using the product over a short period, but it lacked a control group and did not clearly explain how volunteers were selected. It also failed to standardise how the serum should be applied or prevent participants from using other skincare products alongside it.

Additionally, the results were based on self-assessment rather than objective measurements, making them less reliable. Regulators noted that such subjective feedback could not be considered strong scientific proof.

Further issues included the study being carried out in a climate different from the UK, with varying environmental conditions and skin types. This raised questions about whether the findings could accurately reflect real-world use by British consumers.

Other supporting studies were either deemed irrelevant or insufficient, while the cited academic paper focused only on a key ingredient rather than the finished product itself.

Regulator’s Final Verdict

The ASA ultimately ruled that the claim of achieving a visibly younger appearance by up to five years within four weeks was misleading. As a result, the advertisement has been banned from appearing again in its current form.

The watchdog also instructed the company not to repeat such claims unless they are supported by robust and credible scientific evidence.

Company Response

In response, Beiersdorf stated that its product claims are grounded in scientific research and conducted in line with industry standards. The company acknowledged the ruling and confirmed that the specific UK advertisement has already been withdrawn.

Despite the ban, the company maintained confidence in the effectiveness of its products and the research behind them.
