Natural Efficacy

 

 

 

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,

Spa Treatment Expertise


 

The first step in the brand’s story was the creation of phyto-aromatherapy.

Aromatherapy is therapy using essential oils. The researchers took this idea and added active ingredients drawn from all the natural substances contained in a plant. This created new synergies and the notion of phyto-aromatherapy was born. 

Professionals were attracted to and convinced by the efficacy, the power of the balancing aromas, the immediately visible results after treatment, and the feedback from clients. At that time, Yon-Ka were only available in France.

 

 

Multisensory Experience

 

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"
