About Julie

Scientific and creative, I support players in the beauty industry in the development of their products, from ideation to market launch.

Product development consultant, I intervene on:

âś… Innovation & formulation: market watch, opportunity identification, ingredient and packaging selection.
✅ Regulation: international compliance (USA, EU, UK…), certifications (COSMOS, EWG, Peta…).
✅ Development & industrialization: project management, coordination with subcontractors, definition of necessary tests (stability, efficacy, tolerance…).
âś… Communication & engagement: team training, product storytelling, consumer interactions.

With experience at LVMH Research and Juice Beauty, and as the founder of an organic skincare brand, I have managed the development of over 50 product launches.

👩‍🔬 I work on both specific projects (certification, reformulation,…) and long-term assignments.

🎙️ Passionate about cosmetics and its impact, I also host the podcast Les Dessous de la Cosmétique (+40K listens).
