The Meaning Behind Yon-Ka: Homage to the Egyptian symbol of infinite rejuvenation

YON (Life-giving river with cleansing waters, and phonetic link ION, or energy particles) and

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!”
