Chrystelle Lannoy,

Gemology Founder 

Our history

13 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 expertise

"At the center of a major innovation, our laboratory has developed, after three years of research, a technology to extract trace elements (Iron, Zinc, Magnesium, Copper...) from stones such as Sapphire, Peridot, Ruby...

These trace elements enable to stimulate the biological functions to prevent, repair and protect the skin from time passing and our oxidative environment."

Dr. Jean-Claude Bozou


Lacks in trace elements are growing these days due to a poorer intake of trace elements : food and drink are poorer in trace elements, living conditions are more stressful… Hence, complementary sources of trace element are very important.

By bringing trace elements directly to the skin, their assimilation is immediate. They play a quick, direct and efficient role in solving all skin troubles.

Gemology goes beyond cosmetics with skin oligotherapy.
