Founded in 1954 by botanist brother Charles and Ernest Mühlethaler and operated today by their daughters and nieces Françoise and Catherine Mühlethaler, Yonka has provided users with decades of high quality skincare products. Through fusing together the complex science of four botanical therapies - Aromatherapy, Phytotherapy, Marine-Therapy, and Fruit-Acid Therapy - as well as through incorporating fragrant essential plant oils with plant and marine extracts, Yonka offers a vast array of complimentary products that regenerate and restore the texture and appearance of the skin. This hand-crafted, plant derived and holistically formulated product line is ideal for all ages and all skin types. We do not ship Yonka products outside of Canada.
