Formulator's Corner: Expert Guidance from Chloé Fournier
Bridging the gap between rigorous cosmetic science and creative botanical skincare. Master the art of professional formulation today.
The Philosophy of Professional Formulation
In the rapidly evolving world of 2026, the demand for transparency and efficacy in skincare has never been higher. Yet, there remains a significant gap between "DIY" kitchen mixing and professional cosmetic chemistry. Chloé Fournier, a veteran cosmetic chemist with an M.S. in Cosmetic Science and over a decade of experience in the European luxury market, created the Formulator's Corner to bridge this divide.
Our mission is to empower the next generation of skincare entrepreneurs and enthusiasts with the scientific tools necessary to create safe, stable, and high-performance products. Whether you are interested in Clean Beauty Ingredients or the complex Science of Skincare, understanding how to build a formula from the ground up is essential.

The Stability Challenge: Preservatives & Emulsifiers
One of the most common pitfalls in natural skincare formulation is the reliance on inadequate preservation. Many "natural" preservatives on the market in 2026 fail to meet standard challenge testing (ISO 11930). At Formulator's Corner, we focus on Evidence-Based Preservation.
We teach you how to analyze the chemical structure of ingredients like Capryloyl Glycine or Sodium Levulinate. It's not just about adding a drop of Vitamin E; it's about understanding water activity, pH hurdles, and chelating agents.
Emulsification Science
Creating a professional cream is an exercise in thermodynamics. We deep dive into the HLB System (Hydrophilic-Lipophilic Balance) and the use of co-emulsifiers to create liquid crystal structures. These structures not only improve stability but also mimic the skin's natural lipid barrier, enhancing delivery.

Formulating for Skin Type & Target
Oily & Acne-Prone
For oily skin, we focus on Oil-in-Water (O/W) emulsions with a low internal phase (10-15% oils). In our Clean Beauty Routines guide, we emphasize ingredients like Niacinamide and Willow Bark Extract. In the lab, this requires stabilizers like Xanthan Gum or Sclerotium Gum to prevent syneresis without adding "tackiness."
Dry & Mature Skin
Rich, nourishing creams often utilize Water-in-Oil (W/O) emulsions or high-oil-phase O/W systems. We explore the use of Ceramides and Phytosterols to repair the skin barrier. Formulating these requires high-shear homogenization to ensure small droplet size and long-term shelf stability.
"Skincare formulation is where the precision of mathematics meets the intuition of art. Our goal is to give you the confidence to excel in both." — Chloé Fournier
Formulation FAQ
Can I truly make professional products without a chemistry degree?
While a degree provides a strong foundation, modern formulation resources and our specialized training bridge the gap. We teach the practical application of chemistry specifically for skincare, focusing on safety and stability above all.
Are all 'natural' preservatives safe?
Not necessarily. Some botanical extracts are marketed as preservatives but lack broad-spectrum efficacy. We guide you through common questions about ingredient safety and how to select robust systems.
What equipment do I need to start?
You don't need a million-dollar lab. A high-precision scale (0.01g), an overhead stirrer or high-shear blender, a pH meter, and heat-resistant glassware are enough to create retail-quality prototypes.
How do I test the shelf life of my products?
We teach Accelerated Stability Testing, where products are kept at elevated temperatures to simulate aging. This is a crucial step before any commercial launch.
