Frequently asked questions

We are two pharmacists. We research beauty recipes from history and design a theoretical formula with the active ingredients and concentrations we want. Our partner laboratory, Ocealys, then adapts it for manufacturing. Our formulas are developed in the Bretagne region and manufactured in the Pays de la Loire region (France).

“The cosmetics marketplace” in Greek: kosmētikos (the art of adornment) and agora (the gathering place).

Yes, but not all of their ingredients. They often mix effective ingredients with others that were kept because they could not be separated, or added out of belief, tradition or religion. Our job is to tell them apart and keep only what science has proven to be effective.

Both were powerful women and victims of rumours: the “femme fatale” and the “vampire”. Historians agree that these stories have little to do with reality: most likely, they were victims of their rivals’ political strategies. We want to give them back their rightful place as women who changed history.

Yes. In the European Union, testing cosmetics on animals is banned: finished products since 2004, ingredients since 2009, and the sale of tested products since 2013. We go further: we favour plant-based or synthetic ingredients and, when an animal-derived ingredient is essential for efficacy or safety, we require cruelty-free certification, including for ingredients imported from outside the EU.

The Vital Elixir Serum is vegan. The Moisturizing Milky Toner is not: its milk peptides are essential to its soothing efficacy.

The Moisturizing Milky Toner is 99% of natural origin and winner of the EBNA Excellence Award 2026. The Vital Elixir Serum is 84% of natural origin: its 15% urea is synthetic, currently the cleanest, most effective and safest way to obtain this ingredient.

Yes. Follow the sorting instructions on the label. We are members of CITEO, the French national organisation for the collection and recycling of packaging.

The serum is a treatment: its high urea concentration and fast absorption can cause tingling, which sensitive skin could mistake for a reaction. The toner absorbs more slowly and its lipids seal the skin, so it is better suited to the daily care of sensitive skin. We define efficacy first, then position each product according to its tolerance.

Yes. Skin differences between genders or origins do not justify separate ranges, except for specific concerns such as beards or pigmentation disorders.

There are three levels of proof in cosmetics: relying on a well-known ingredient (the weakest); self-assessment, where users rate statements (for example, 88% noticed more radiant skin); and instrumental clinical testing, where devices or experts measure the skin before and after treatment. It is the most demanding, and we submit the main claim of each product to it. Its results (−13% wrinkles, +20% hydration) are more modest, but they are the most reliable.

Yes, they contain no comedogenic ingredients. If you have doubts or recurring acne, choose the serum, which contains no fatty ingredients.

From 16 years old.

Yes, both products work as a makeup primer.

Yes. If in doubt, write to us and we will look at your case.

The serum contains no retinoids, salicylic acid, hydroquinone or essential oils. The toner contains bergamot essential oil at a very low concentration in its fragrance. We have not carried out a specific assessment for pregnancy, so we recommend you ask your doctor or pharmacist.
