What One Formula Can Do: A Conversation with Dr Natacha Bonjout, Founder of Bonjout Beauty

When Natacha Bonjout was 12 years old, a chemist told her: if you want to understand skin, study pharmacy. She followed that advice. She earned her Doctorate in Physiology of Skin Complexion in 2010 at the Research Labs of Chanel in Paris. Then she worked for 15 years developing cosmetics at Chromavis and Naturex, where she studied over 700 ingredients and tested more than 2,000 formulas.
After all that experience, she asked herself one question: what would it take to create a single product, made with the same care as medicine, that could be enough on its own?
Le Balm took 5 years to create. It contains 68 ingredients. It's waterless, solid, and can be used in many ways. It works on skin repair, moisture, protection, and renewal all at once. The 2.6.60 system (two skin layers, six actions, sixty-plus ingredients) isn't just marketing. It's a scientific method, the same kind used to develop medicines, applied to skincare.
What makes Bonjout special isn't just that it's one product. It's the belief behind it. Natacha doesn't think fewer products are always better. She believes that one product made with scientific precision, the right amounts of ingredients, and ingredients that work well together can do more than several products made without that care. The simplicity is the outcome, not the starting point. It came after testing 2,000 formulas, hundreds of versions, and years working in labs where French skincare was held to the same standards as medicine.
In this conversation, we discuss what scientific formulation really means: how ingredients are chosen, how products are tested for safety, and how they're designed to work on skin. We talk about keeping skin healthy over time (not trying to reverse aging, but helping skin work well for longer). And we discuss what it means to launch with just one product when most brands create entire product lines.

You've spent over 15 years in cosmetic R&D and pharmaceutical formulation. What led you to move beyond the traditional French pharmacy and create a new chapter of skincare with Bonjout and ultimately Le Balm?
After more than 15 years in cosmetic R&D, I saw that skincare had become increasingly complex, yet skin health was not improving in a meaningful way. As a French pharmacist, I was trained to believe that more does not mean better. I wanted to move beyond the traditional French pharmacy model and create a new chapter of skincare—one rooted in pharmaceutical precision, simplification, and long-term skin health.
Le Balm became the embodiment of that vision. Each formula is meticulously crafted with the same intention, precision, and detailing as a piece of "haute couture" We embody Haute Formulation Craftsmanship. Refined over multiple iterations, clinically evaluated, and exhaustively perfected for both performance and sensorial elegance, each step is thoughtful, carefully considered, and takes time. That level of formulation craftsmanship allows us to deliver fewer products with higher efficacy and long-term, visible results.
Bonjout challenges the idea of multi-layer routines. Why do you believe fewer products can actually deliver better results?
In France, we don't believe that more means better. Skin is a living organ, and when it's overwhelmed with too many layers, it often becomes sensitized and imbalanced. True efficacy comes from using the right ingredients, at the right concentrations, in formulas designed to work synergistically.
Bonjout is built around the idea that you can do more with fewer steps when the formulas are thoughtfully crafted. Simplifying routines allows the skin to restore its natural functions—especially barrier integrity—which is essential for long-term radiance.
Le Balm is often described as a solid serum developed with pharmaceutical precision. What does that actually mean in practice?
Pharmaceutical precision means formulating with the same rigor used in dermo-cosmetics—careful ingredient selection, stability testing, and clinically relevant concentrations. Every component in Le Balm has a role and is evaluated not only for efficacy, but for how it interacts with the skin over time.
The solid, waterless format allows us to protect delicate actives, eliminate unnecessary preservatives, and maintain optimal stability. It's a highly controlled delivery system designed to treat skin, not simply coat it.
Instead of focusing on instant results, Bonjout emphasizes skin longevity. How should users think about radiance over time?
Radiance is often misunderstood as an immediate glow, but true radiance is the result of healthy skin function. When the barrier is strong, hydration is balanced, and cellular renewal is supported, radiance becomes consistent and lasting.
With Le Balm, users often notice comfort and improved hydration quickly, but the real transformation happens over weeks and months. Skin becomes more resilient, even-toned, and naturally luminous. That's the difference between short-term effects and long-term skin health.
Launching with a single, multi-functional product is rare in today's beauty market. Why was this approach so important to you?
For me, luxury today is not about excess, it's about restraint and excellence. Creating one multi-functional, high-performance essential allowed us to focus entirely on quality, precision, and results. By doing less, we can do better. One product that replaces multiple steps reduces friction in daily routines while delivering superior efficacy. This is a more sustainable, intelligent approach to skincare—and one that respects both the skin and the consumer.
How do your French heritage and pharmaceutical background shape Bonjout's long-term vision?
My French heritage is at the core of Bonjout. In France, pharmacists are deeply trusted skincare experts, and dermo-cosmetics are held to extremely high standards. That mindset shapes every decision we make, from formulation to philosophy. As Bonjout grows, our focus remains the same: pharmaceutical precision, thoughtful craftsmanship, and formulas designed for long-term skin health. Expansion is never about speed, it's about maintaining integrity, wherever the brand lives.
