YonKa gives your skin the means of rediscovering and preserving its balance and beauty. Created in 1957 by two brothers, both botanists, by stabilizating essential oils in a water-based emulsion, YonKa uses the complex science of four botanical therapies - Aroma-Therapy, Phyto-Therapy, Marine-Therapy and Fruit-Acid-Therapy - in a line of therapeutic, nurturing and healing products.
