THOYA Laboratoire strives to develop high-quality, plant-based, and hypoallergenic formulations that protect, nourish, and hydrate the skin (from the most sensitive to all skin types) exposed to harmful environmental factors. All our product are designed with effective and non-toxic natural-origin ingredients.  


Elizabeth Hartinger, Ph.D., M.A.Sc., B.Eng., Founder & President

Elizabeth is committed to cutting-edge skin research and has acquired over the years extensive experience in dermatological technologies. Her postdoctoral studies were conducted at Harvard University and Massachusetts General Hospital in Boston, USA, where she worked on a novel laser technology in the field of dermatology. Elizabeth completed a doctoral and a master degree in biomedical engineering at Montreal University/Ecole Polytechnique in Montreal, Canada. While pursuing graduate studies, she developed an innovative technology for skin cancer detection and acquired comprehensive knowledge of the skin and cutaneous pathologies.

Preoccupied by both the harmful environmental factors and the large amount of chemicals in everyday skincare, Elizabeth founded THOYA Laboratoire as a commitment to develop a new generation of hypoallergenic professional  skin care  with highly effective, carefully selected, safe, all natural origin, and organic ingredients.
