Professional Skin Care & Beauty Since 1999
A pioneer of aromatherapy and phytotherapy in professional skincare, Yon-Ka was founded in France in the 1950s by the Muhlethaler family. What began as a passion for botany has matured over the decades into a worldwide skincare company and one of the most respected names in the professional beauty industry. Today, Laboratories Multaler — Yon-Ka's parent company — manufactures a complete herbaceutical range of face, body, and sun care products using pre-dosed essential oils and botanical extracts sourced from around the globe.
Yon-Ka products are crafted from the finest, purest ingredients available. Over 70% of Yon-Ka products are composed of more than 90% natural ingredients, and every formulation is rooted in one of four botanical therapies: Aromatherapy, which treats through the therapeutic power of scent; Phytotherapy, the ancient practice of herbal medicine; Marine Therapy, harnessing the nutrient-rich extracts of marine plants; and Fruit Acid Therapy, employing natural fruit acids to promote healthy cell turnover and renewal.
At the heart of every Yon-Ka product lies the Quintessence — a proprietary combination of five essential oils derived from the Mediterranean region: lavender, geranium, rosemary, cypress, and thyme. These five oils are designed to work in synergy, creating an optimal therapeutic outcome that is greater than the sum of its parts. Currently, over 130 plants from every continent are used in the composition of the Yon-Ka range, but the Quintessence remains the signature thread that unites the entire collection.
What truly distinguishes Yon-Ka from other botanical skincare brands is their commitment to pharmaceutical-grade manufacturing standards. Their 75,000-square-foot production facility houses an in-house Research and Development, Quality, and Applications department staffed by chemical engineers, pharmacists, aestheticians, and biologists who work together to continually refine and improve every product in the range. This level of scientific rigor applied to natural ingredients is rare in the skincare industry and ensures that every Yon-Ka product delivers consistent, reliable results.
Using a holistic approach grounded in transparency, authenticity, quality, safety, and proven effectiveness, Yon-Ka unites nature with science to intensely energize the skin. The brand's founding values celebrate the art of the beauty ritual — the idea that skin care should be not merely functional but a sensory experience of fragrance, harmony, and luxury. This philosophy is embodied in L'ESPAce Yon-Ka, the brand's own spa on the Left Bank in Paris, where guests discover an enchanted haven of peace in which to unwind.
Yon-Ka has long been a Skin1 favorite, enjoyed by devotees of every age and skin type. For another product from the Yon-Ka range, see the Yon-Ka After Sun Lotion Tan Prolonger.
