A human-scale team: you talk directly to the people who develop, plan and control your products, from the first sketch of a formula to the final quality check.
Behind every project, the same three people support you from start to finish. Get to know them: each one introduces themselves here in their own words.

Julien B.
Co-founder - Planning, supply chain & quality
With solid experience in planning, supply chain and quality monitoring, I take real pleasure in giving our clients the responsiveness their needs call for. Deeply involved in continuous improvement and committed to consistent quality, I make a point of always looking for the best answer to every challenge.
Christèle
Formulation scientist
After a technical degree in cosmetology, a professional bachelor's in formulation and a master's in cosmetics engineering, I joined Costomise on a work-study placement - and I never left. What led me to formulation is a taste for creating; what keeps me here is watching our textures become real products.
From one end of your project to the other, you always know who is looking after what. Here is how we share the stages between us, and when each of us steps in at your side.
To get to know us better, you can also read who Costomise is and our story.
From the very first conversation, Julien R. takes the time to understand your idea and turns it into a clear brief: positioning, formulation type, preferred ingredients.
In the laboratory, Julien R. and Christèle develop your formulas trial after trial, and have you approve each texture until it truly matches your project.
Julien B. maps out the stages of your project over time, looks after the regulatory compliance of your products and ensures consistent quality, batch after batch.
Julien B. again follows manufacturing and supplies, and stays at your side until your products are delivered.
The team at work, in our Marans laboratory.
A laboratory based in Marans, near La Rochelle, where your products are formulated, manufactured and controlled.
A question, a project, a hesitation? At Costomise, you talk directly to the people who formulate and manufacture your products.
