About Us
Menu
At Yon-Ka, we believe that in order to reach greater physical and mental well-being, each person must reconnect with themselves and return to what’s essential to live better longer.
We create essential experiences that strengthen each person’s balance and vital energy using effective, personalised phyto-aromatic products that don’t aggravate skin.
Who we are?
Pioneers in aromatherapy, Laboratoires Multaler created Yon-Ka® Paris phyto-aromatic skincare products in 1954. Yon-Ka is a family-owned, 100% French brand whose products give your skin the most vital elements from plants: their revitalising essential oils filled with energy from the sun and complementary active ingredients (vitamins, fruit acids, polyphenols, peptides, and trace elements).
This combination precisely, gently, and effectively meets the needs of the most demanding skin.
Our manifesto:
- “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-Ka…The brand’s name itself carries a symbol of continual regeneration:
YON, the purifying whitewater river and, phonetically similar to ‘ion’, the energy particle.
KA, the eternal soul that lives in each being, a word from the time of the Egyptian Pharaohs


Our story
Passionate about aromatherapy and phytotherapy, the Mühlethaler family has been experimenting with their various properties since 1954. Yon-Ka has always drawn inspiration from the benefits essential oils and plants bring to the mind and body while also meeting specific daily 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 phyto-aromatic brand.
Our values
Anchored in the present and committed to the future, we want to share a new form of holistic beauty that respects the body and mind, as well as nature, its resources and the living beings that fill it.
We are committed to continually improving the way we work to make a positive impact on the world. Our mission is embodied by the brand’s five unique values: natural efficacy, formulation excellence, spa treatment expertise, multisensory experience, and sustainable commitments.


Nos Formules
Yon-Ka promotes scientific rigour and develops our strength and efficacy through formulation excellence and exacting requirements. We do all of this with respect for animals and the environment, and exclude a list of harmful ingredients. The brand also favours gluten-free and vegan formulations with 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 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 ingredients
Laboratoires Multaler carefully selects all ingredients in our products as well as our suppliers, who must all follow our quality charter. We carefully select the best plant active ingredients (certified organic whenever possible) and the best essential oils to create an effective, natural beauty escape that fills our customers’ senses. Yon-Ka products contain at least 92% natural ingredients. Yon-Ka’s very essence is contained in our exclusive complex of essential oils, a veritable concentration of efficacy: Yon-Ka Quintessence.


Nos Collections de produits
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.
