Brand Info

Yon-Ka… These two syllables form a whole that is greater than the sum of its parts. "Yon" is the river of living, purifying water, and sounds similar to "ion," particle of energy. "Ka" is the eternal part of every being according to Egyptian mythology. Yon and Ka unites what seems contradictory: knowledge and mystery, science and nature, movement and rest, shadows and light. Together they form a symbol of constant regeneration and newfound harmony.

Created in 1954, pioneer in the realm of phytoaromatic treatments and rich with international experience, Yon-Ka provides your skin with the most precious part of plants: their revitalizing essential oils full of solar energy and complementary active ingredients - vitamins, fruit acids, polyphenols, peptides, oligoelements... - Synergy which acts with precision, kindness and effectiveness for the specific needs of the most demanding skin types.

In the heart of Yon-Ka products and treatments, is "Quintessence." The exclusive formula combines 5 essential oils with extraordinary powers - lavender, geranium, rosemary, cypress, thyme - a treat for the senses which reinforces the effectiveness of the natural active ingredients from plants from all over the world.
