Our mission statement:

“In a world that’s always demanding more,
we pause. We take stock.
We get back to what’s essential.
Less pretence, more authenticity,
Less compromise, more efficacy,
Less talking, more feeling.
At Yon-Ka, we always choose simplicity in good conscience.
We reconnect with our own energy and that of others,
so that tomorrow’s world will be healthier and more beautiful.”

Yon-Kaa…The brand’s name itself carries a symbol of continual rejeuvenation:
YON, the purifying whitewater river.
KA, the eternal soul that lives in each being, a word from the ancient Egyptian Pharaohs

Our story

Passionate about aromatherapy and phytotherapy, the Mühlethaler family has been leading the way with their various discoveries since 1954. Yon-Ka has always drawn inspiration from the benefits essential oils and plants offer the mind and body while also meeting specific daily, real world, needs for women and men.

Their research led them to a major discovery: “Quintessence”, a unique combination of 5 essential oils from the Mediterranean basin which became the DNA of their trademark phyto-aromatic brand.

Our values

Alive in the present and committed to a bright future, we want to share a new form of holistic beauty that pays respect to the body and mind, as well as the nature around us, its resources and the living beings that fill it.

We are committed to constantly improving how we work to make a positive impact on the world. Our mission is empowered by the brand’s five unique values: natural efficacy, formulation excellence, spa treatment expertise, multisensory experience, and sustainable commitments.

Our Formulas

Yon-Ka promotes scientific rigour and draws on our strength to achieve efficacy through excellence in formulation and exacting requirements. We respect for animals and the environment, and don’t use any harmful ingredients. The brand also favours gluten-free and vegan formulations using a high number of natural ingredients.

Yon-Ka tests each product’s efficacy (firming, wrinkle depth, hydration, anti-glycation, antioxidant, and dark spot correcting properties, etc.) through clinical and instrumental trials and studies conducted by independent labs: efficacy tests using instruments, efficacy and tolerance tests supervised by dermatologists, tests on cell cultures and skin explants, as well as consumer validation of our products’ textures and fragrances.

Our Product Collections

To recreate the spa experience at home, Yon-Ka has developed a range of products for the face and body that prolong the benefits of professional treatments. Each formula created by our labs embodies our desire to provide an effective, targeted response for every stage of life that solves all skin issues (hydration, anti-ageing, nutrition, radiance, uniformity, anti-redness, purity) for all skin types.

Our Commitments & Actions

We have the greatest respect for Nature, as well as for the women and men who work to produce, grow, and harvest its resources since they’re essential components in our premium skincare products. As a family-owned French company, we make it a point of pride to have all our products manufactured in France by the most sustainable and local partners who care about biodiversity and equity. So, naturally, Yon-Ka is committed every day to protecting nature, notably by supporting the work of Un Toit pour les Abeilles (A Roof for Bees).Our company also supports breast cancer research through the Ruban Rose (Pink Ribbon) organisation.
