About our Founder 

Preoccupied by both the harmful environmental factors and the large amount of chemicals in everyday skincare, Elizabeth Hartinger, Ph.D., M.Sc.A, B. Ing. 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.

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 and skin cancer. 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.

At THOYA Laboratoire, researchers are committed to work on next-generation products designed to protect, maintain and optimize the health of the skin.

THOYA Laboratoire all Natural Mineral Sunscreens

THOYA Laboratoire uses only non-nano zinc-oxide mineral UV filter (no titanium dioxide, no avobenzone, no oxybenzone, and no chemical filters) in its sunscreens. Zinc oxide remains a safe and naturally-derived mineral filter approved by Health Canada that provides safe and highly effective broad-spectrum sun protection against both UVA and UVB rays.

Mineral filters do not penetrate the skin barriers unlike many chemical filters which are systemically absorbed. 

Mineral sunscreens also have a much lower rate of photoallergic reactions than chemical filters and zinc oxide has even been shown to reduce cutaneous irritation and redness.  Zinc-oxide mineral sunscreen is recommended for all skin types including the most sensitive. A must after a dermo-aesthetic treatment including laser, peel, facial, etc. 

Our sunscreens are enriched with antioxidants from fruit extracts for a healthy looking skin. They moisturize and protect against environmental factors drying the skin, such as the sun and pollution. THOYA Laboratoire sunscreens protects and smooths all skin types while preventing premature signs of aging resulting from everyday sun exposure. They spread easily leaving no residue. Perfect and safe for all the family.
