Understanding this distinction is becoming increasingly important as consumers encounter a growing number of claims about anti-aging effects, hydration, skin repair, natural ingredients, and “high-performance” formulations. While these messages may sound similar, the regulatory framework behind them is not.
The First Requirement: A Cosmetic Must Be Safe
Before a cosmetic product reaches the European market, it must comply with strict safety requirements established by Regulation (EC) No 1223/2009.
This means that manufacturers cannot simply formulate a product and place it on shelves. Every cosmetic must undergo a scientific safety assessment that evaluates the ingredients used, their concentrations, expected exposure levels, and the intended users of the product.
The assessment considers factors such as how often the product will be applied, where it will be used on the body, and whether vulnerable populations may be exposed. The conclusions are documented in the Cosmetic Product Safety Report (CPSR), a key element of the product’s regulatory file.
As a result, products legally marketed in the European Union are expected to be safe when used under normal or reasonably foreseeable conditions.
Safe Does Not Mean Risk-Free
One of the most persistent misconceptions among consumers is the belief that a safe product should never cause an adverse reaction.
In reality, no assessment can guarantee identical outcomes for every individual. Human skin varies considerably, and certain people may be more susceptible to irritation, allergies, or intolerance to specific ingredients.
A product may therefore comply fully with regulatory requirements and still trigger an unwanted reaction in a small number of users. This is precisely why ingredient disclosure, allergen labelling, warnings, and instructions for use play such an important role in cosmetic regulation.
Safety assessments are designed to ensure an acceptable level of risk for the general population—not to eliminate every possible individual response.
Performance Is a Different Regulatory Matter
While safety is mandatory for market access, proving efficacy is not a prerequisite for selling a cosmetic product in the European Union.
This point often surprises consumers. A cosmetic product does not need prior authorization demonstrating that it delivers exceptional results before it can be marketed.
However, the situation changes as soon as specific claims are made.
If a company states that a product moisturizes the skin, reduces the appearance of wrinkles, improves radiance, or provides another measurable benefit, those statements must be supported by appropriate evidence. Under Regulation (EU) No 655/2013, cosmetic claims must be truthful, substantiated, and not misleading.
In other words, the law regulates what companies can promise, rather than requiring all cosmetic products to demonstrate efficacy before entering the market.
Why Consumer Expectations and Regulatory Reality Often Diverge
Many purchasing decisions are driven by a desire for visible results. Consumers naturally want to know whether a cream, serum, or shampoo will meet their expectations.
The challenge is that expectations are highly personal.
A user seeking significant wrinkle reduction may evaluate a product very differently from someone whose primary goal is daily hydration. Likewise, a formulation designed to improve skin comfort may be considered successful by one person and disappointing by another.
This is why broad statements such as “this product is good” or “this product does not work” rarely provide meaningful information. They often reflect individual experiences rather than objective assessments.
The Human Factor: Why Results Vary
Unlike medicines, cosmetics are used on highly variable biological systems. Skin characteristics differ according to age, genetics, environmental exposure, lifestyle, and existing skin conditions.
Even when a product demonstrates positive results during testing, individual outcomes may vary considerably.
A moisturizer that delivers statistically significant improvements in hydration during controlled studies may produce noticeable benefits for some users while generating more modest effects for others. This variability is not necessarily a sign of poor formulation; it is a consequence of biological diversity.
Understanding this principle helps explain why customer reviews can differ dramatically for the same product.
Why Regulatory Authorities Prioritize Safety Over Performance
From both a legal and ethical perspective, consumer protection comes before commercial claims.
A highly effective product that presents unacceptable safety concerns cannot remain on the market as a cosmetic product. Conversely, a product with modest performance may still be legally marketed provided it is safe and does not make unsupported claims.
This hierarchy reflects the fundamental objective of cosmetic legislation: protecting human health while ensuring fair and truthful communication.
A Better Way to Evaluate Cosmetic Products
For both professionals and consumers, asking the right questions leads to a more accurate understanding of a product.
Rather than asking whether a cosmetic is simply “good,” it is more useful to consider three separate questions:
Is the product compliant with safety requirements?
Are the claims supported by appropriate evidence?
Is the product suitable for the specific needs and expectations of the user?
These questions provide a clearer framework for evaluating cosmetics and reduce the gap between marketing expectations and scientific reality.
