Hailing from Canada, I grew up with a great love for the outdoors and an appreciation for the simple things in life. Self-care in my home was as much in the kitchen as in front of my bathroom mirror. There were always several bottles of vitamins and supplements on the kitchen counter as well as numerous jars of creams and serums in the bathroom. During my teens, I started wondering what really contributed most to my mother’s luminous complexion and whether all, if any, of these products were really necessary.

After spending the last 20 years in Europe and starting a family of my own I have become more concerned and vigilant about the products I put into my own and my children’s bodies. Indeed, as a seemingly endless number of skin care and supplement brands hit the shelves every week, each boasting of their green, clean, organic, sustainable, botanical, potent but gentle ingredients, I often felt overwhelmed and sceptical about the effectiveness and safety of these products. Working myself for a large multinational company, I was frustrated with all the reenwashing I saw around me. Many of my friends shared this concern and had a hard time deciding what beauty brands they could trust.

Slowly but surely, the idea that I could create a trustworthy brand that was up to my quality, sustainability and aesthetic standards was starting to blossom. A meeting convinced me to take the leap. In 2018, I met Philippe Guillermic, who was passionate about naturopathy and Korean medicine. Design and creative director by trade, he worked for major hotel brands, luxury brands and urban wear brands, as well as co-founded Cosmydor, a luxury artisanal skincare brand.

We were driven by the same desire to create a brand that combined the best of clean bioactive skincare, nutricosmetics and wellness supplements, in a global logic of "self care". Assisted by Nara Nairi, a medical doctor and expert in micro-nutrition, we wrote an extremely strict set of product specifications that would be the starting point of this adventure.

After two years of study and research based on the conviction that beauty and wellness are an indissociable whole, DAYS OF CONFIDENCE was born, offering products of outstanding quality, efficiency, integrity, and aesthetically pleasing.

If Frédérique is a hyperactive person eager for new knowledge and new encounters, Philippe is more into observation and contemplation of the world and nature. "We are permanently immersed in the effervescence of rich multicultural environments and yet manage to disconnect ourselves from the permanent hubbub of the cities. We live between Madrid, Paris, Biarritz and a small village in Normandy. It is here that we have set up our creative workshop where we develop our formula specifications as well as our packaging and the entire visual universe of our brand. Whereas our travels and encounters inform us about the needs and desires of women and men concerned about their wellness and the health of their skin, it is always in nature and silence that we find our inspiration. It is perhaps the fact of having an acute awareness of both the strength and fragility of nature that lead us to make no compromise on the sustainable design of our products which, along with their effectiveness, are the fundamental keystone of our formulas.


Doctor Nara Nairi has a multifaceted academic background: she was educated at the Faculty of Medicine in Moscow (Russia), the Faculty of Biological and Pharmaceutical Sciences of Paris (France) and worked for seven years in the pharmaceutical industry in France and the UK. She has been awarded a Postgraduate Diploma in Micronutrition at the Faculty of Medicine of Dijon (France) and a Master’s Degree in Law, Economics and Marketing of Healthcare System at the University Paris Sud (France). Since establishing herself in London, Doctor Nara Nairi has been running her own private clinic in Functional Medicine, Micronutrition and Microimmunotherapy providing with a holistic approach in the quest for optimal health and wellness. She lectures on this discipline internationally. She is closely involved in her patients’ care offering them recommendations, individual follow-ups and support in every step of their pathway to recovery and optimal functioning.

Dr Nara Nairi also acts as a consultant for pharmaceutical companies and private hospitals to contribute to their business development and project management.

Convinced of the virtue of the nature and our innate programmed capacity to recover, Dr Nara Nairi is committed to bring their power to the service of her patients and the projects she works on.

Dr Nara Nairi lives in London and Paris and is fluent in English, French, Russian and Italian.
