The Origins of Our Brand Name
Yon-Ka’s unique essential oil complex, delivers the unique olfactive and therapeutic experience that Botanists and Egyptologists by trade, social and beauty conservationists by nature, visionary brothers Charles and Ernst Mühlethaler and his wife Cecile created a skincare brand that married artistry and science to serve the people and planet with multi-sensory formulations consistent in all their products (which remains paramount to the Yon-Ka Paris company mission.)

YON (Life-giving river with cleansing waters, and phonetic link ION, or energy particles) and
KA (the part of eternity found in every being in ancient Egypt.)

Under the vision of the sisters
Disruptors of the skincare industry since 1954, The Mühlethaler family chose natural plant-based ingredients versus chemical and synthetic elements (commonplace at the time) to create extraordinary products. They pioneered the use of aromatherapy in beauty products through the power of nature with results-driven expert formulas; a commitment to authenticity and simplicity that remains true to the brand.
In 2010, Catherine and Francoise Mühlethaler developed the new face of Yon-Ka Paris, recognized world-wide with their signature collection: The Anti-Aging System, consisting of the Defense Range, Corrective Range, and Age Exception Range to treat skin through every stage of life, while other beauty brands cherry-pick skin ailments, the Yon-Ka Paris luxury brand addresses a bevvy of skin issues consumers face, with subsequent personalized products: the Specifics Collection, Essentials, Body, Sun, and Men’s skincare lines.
The Mühlethaler Motto: “If you believe in something, do it!”
