For over 65 years, Yon-Ka has been sharing its passion for plants with consumers and beauticians around the world through its phyto-aromatic face, body and sun care combining the benefits of aromatherapy, aromachology, phytotherapy and gemmotherapy.
Its objective: to offer women and men, in any climate, the visible and lasting effectiveness of Nature's resources. Each active ingredient is scientifically analysed and dosed to give the skin the means to recover its balance, alleviate its problems and slow down the signs of time.
The effectiveness of each product - firming action, anti-wrinkle, moisturising, anti-glycation activity, anti-oxidant, anti-spot ..., is objectively validated by studies conducted by independent laboratories :
- Objective tests by instrumental measurements
- Efficacy and tolerance tests under dermatological control
- Tests on cell cultures and skin explants
Driven by exacting standards and pharmaceutical rigour, our team of experts (doctors, pharmacists, chemical engineers, biologists, and bacteriologists) develop formulas with the right concentrations, with the best efficacy/safety ratio for visible and lasting results without aggressiveness.
Our gluten-free and mostly vegan formulas, contain on average 92% ingredients of natural origin, preferably organic. Each ingredient is rigorously selected and controlled by our laboratories, both on a physicochemical and bacteriological level.
Our formulation charter respects the strictest international regulations. It bans Parabens, Methylisothiazolinone (MIT), Aluminium salts, Butylhydroxyanisole (BHA), Sodium Lauryl Sulfate (SLS), Phthalates, Triclosan, GMOs, proven endocrine disruptors*. It continuously monitors the evolution of its formulas towards ever more naturalness.
Our production, 100% French, respects the GMP - ISO 22716 quality criteria at all stages of manufacture.
*According to the WHO definition and with reference to the Echa list (European Chemicals Agency)
Spa Treatment Expertise
Our treatment rituals in Spas and Institutes are based on our long experience and, since our creation, on our holistic vision of care and Wellness: chiseled protocols, Eastern and Western techniques, exclusive methods, combination of manual and instrumental techniques... This know-how, we teach to our community of beauty and Wellness professionals to bring you a visible result and to make you experience a great moment of relaxation.
Every Yon-Ka treatment is an expert and subtle alchemy between the professional's hand, the hand that feels and gives, the instrument that extends and strengthens it, the essential oil that optimises it.
From the very first Yon-Ka treatment, you see the difference! To the sight and touch, your skin glows, becomes smoother and more beautiful even without make-up. The skin texture is refined, the complexion is brightened.
A Yon-Ka treatment is a unique, aromatic, holistic and personalised experience combining dermatological effectiveness and powerful multi-sensorial benefits.
And when efficiency is combined with pleasure, it is then the whole being that lights up; the skin regains its radiance, signs of fatigue fade, tensions are reduced under the action of the massage and relaxing or energizing essential oils of lavender, sweet orange, rosemary, jasmine...and those of the Yon-Ka Quintessence.
A parenthesis of Wellness that makes our clients say: "after a Yon-Ka treatment, I feel good, and it shows"
