Brand Story
"With Gemology, I share my passion for minerals and offer you a line of innovative, ultra-efficient French cosmetics based on science. Formulas with trace elements and textures that create emotions, to meet all beauty routines. From the simplest to the most sophisticated."
Chrystelle Lannoy, Gemology Founder
The History
16 years ago, Gemology was able to unveil a secret buried in the heart of minerals. After several years of research and thanks to a scientific approach, Gemology extracts the trace elements from minerals and integrates them into skincare.
Since then, our laboratories have been exploring the functions and benefits of these trace elements on the skin. Skin oligotherapy was born.
Our Values
Science & Innovation
Our research has led to the development of a unique technology for extracting trace elements from minerals through the natural process of solubilization. This has led to the creation of Gemology's innovative complexes, combining the most powerful cosmetic active ingredients with trace elements derived from precious and semi-precious stones.
Quality & Efficiency
Every Gemology formula is clinically tested for effectiveness. Our commitment is to deliver immediate, visible results. Our face and body treatments are precise, sophisticated, unique and ultra-effective.
Creators of Emotions
Every formula, texture, and fragrance is meticulously crafted to create real sensorial experiences. Well-being also lies in the emotions aroused by skincare products.
CSR Commitment
A French brand with ethical and environmental values, we offer products that respect sustainable practices, from the manufacturing process to the point of sale. Ingredients and packaging come from eco-responsible sources.
