For consumers, the distinction can sometimes seem almost irrelevant: if a product is intended to improve the appearance of skin, hair or nails, why should it matter whether it is applied to the body or taken orally?
From a regulatory perspective, however, the distinction matters enormously.
“Nutricosmetics” do not exist as a regulatory category
In the European Union, there is no legal category called nutricosmetics or oral cosmetics. Regulation (EC) No 1223/2009 defines a cosmetic product according to where it is intended to be used and what its principal function is. Cosmetics are intended to be placed in contact with external parts of the human body, teeth or the mucous membranes of the oral cavity for specific cosmetic purposes. Crucially, the Regulation expressly states that substances or mixtures intended to be ingested, inhaled, injected or implanted are not cosmetic products.
This means that a product designed to be swallowed cannot simply be considered a cosmetic because its marketing objective is related to beauty.
The European Commission’s guidance is particularly clear on this point. When a product is intended to be entirely swallowed—for example, a tablet that dissolves in the mouth and is ultimately ingested—it is generally considered a food rather than a cosmetic. By contrast, products such as toothpaste or mouthwash can fall within cosmetics legislation because their intended use is on the teeth or oral mucosa, even though small quantities may be accidentally swallowed.
So what are “oral cosmetics”?
In practice, products marketed using terms such as oral beauty, beauty supplements, nutricosmetics or ingestible cosmetics will generally need to be classified under food legislation, assuming they are not medicinal products or another regulated category.
Food supplements are specifically recognised under EU food law as concentrated sources of nutrients or other substances with a nutritional or physiological effect, and they may be presented in forms such as capsules, tablets, liquids or measured doses.
This creates an important regulatory consequence: the product’s intended route of administration takes priority over its marketing story. Calling a capsule an “oral cosmetic” does not bring it within the Cosmetics Regulation.
Why this matters for manufacturers
For companies developing products at the intersection of beauty and nutrition, classification should be addressed at the beginning of product development—not after formulation, packaging and marketing have already been decided.
A product intended for ingestion may trigger requirements relating to food safety, food supplements, ingredients, labelling and nutrition or health claims, rather than the requirements applicable to cosmetics. Classification can also become more complex when a product makes claims that could move it towards the regulatory territory of medicinal products.
The European Commission describes these as borderline products, where classification must be assessed case by case using the applicable legislation and objective characteristics of the product.
The message for both manufacturers and consumers is therefore simple: beauty may increasingly be connected with nutrition, but cosmetics and food remain legally distinct worlds. “Oral cosmetics” may be a useful marketing expression, but in EU regulatory terms, a product intended to be ingested is not a cosmetic. It belongs to the appropriate food—or, where relevant, another—regulatory framework.
