Many brands still treat regulatory requirements as if they were a final checkpoint before launch. In the EU market, that is too short-sighted. Clear rules apply to cosmetic products: among other things, there must be a responsible person in the EU, a safety assessment including a Cosmetic Product Safety Report, a Product Information File, CPNP notification, and the required labeling. These are not end-stage tasks — they need to be built into the development process from the very beginning.
Product claims should also be formulated and reviewed sooner rather than later. In the EU, cosmetic claims must be useful, understandable, and reliable, and they must be supported by adequate and verifiable evidence. So if a brand starts early with statements such as “particularly gentle,” “long-lasting,” “professional,” or “innovative,” it should also think in parallel about which of these statements can later be communicated in a substantiated way.
In the nail segment, there is an additional layer: the regulatory classification must be carefully assessed case by case. The European Commission itself points out that borderline cases for cosmetic products are evaluated individually. This is especially relevant for nail care products as soon as formulations, functions, or claims move into areas that are no longer clearly cosmetic.
Recent developments around TPO in nail products also show how costly delayed regulatory thinking can become. With Regulation (EU) 2025/877, the European Commission prohibited, among other things, the use of TPO in cosmetic products from September 1, 2025 onward. For some brands, this ban had far-reaching consequences. Anyone who fails to take regulatory developments into account early enough risks unnecessary rush in reformulation, out-of-stock situations, delays, and avoidable costs.
Mistake 5:
There is no clear point of differentiation
Many new brands look appealing, but in terms of content they communicate almost the same things: high-quality products, beautiful colors, good performance, modern design. The problem is not that these points are wrong. The problem is that they are rarely enough to make a brand truly distinctive in a competitive market.
A strong nail cosmetics brand therefore needs a clear differentiating promise. It does not have to be loud or spectacular — but it does have to be clear. That can be achieved through target audience focus, a specific application benefit, assortment logic, quality standards, brand attitude, or curated color worlds. What matters is that it becomes immediately understandable from the outside why this brand exists and what makes it relevant.
If this profile is missing, development often turns into a collection of isolated product ideas. Then colors, products, and messages sit side by side, but no real line is created. That is why the briefing stage should already define which brand core should later be recognizable in the product, packaging, content, and sales approach. Only this consistency turns a launch into a solid brand foundation.
Why these mistakes are so common
Most of these mistakes do not happen because of a lack of motivation, but because of the wrong sequence. Too much work is done too early on colors, names, designs, or product quantities — and too little on positioning, assortment logic, quality framework, and market readiness.
That is exactly why a structured development process is worthwhile. When target audience, brand idea, product roles, regulatory requirements, and future marketing are considered together from the beginning, decisions become easier, briefings more precise, and correction loops much less frequent. This not only saves time, but almost always improves the quality of the final assortment as well.
