Natural actives with proven efficacy

Yon-Ka’s choice for more than 50 years

Ever since our creation, our team of scientist have been devoted  to the selection of  innovative natural active ingredients with undisputed efficiency and originating from:
- either botanicals or marine extracts, such as the essential oils charged with solar energy, anti-oxidant poly-phenols, regenerating peptides, exfoliating and clarifying fruit acids, vitamins, re-mineralizing trace-elements…
- or from biotechnologies, like our amazing hydration booster, hyaluronic acid for plumping, or wrinkles' worst enemy, our yeast extract, which stimulates the elastin production….
 
Our natural plant extracts are carefully selected and scrutinized so that we can guarantee exact percentage of the active molecules in our formulas for a specific and consistent efficiency of our productions.
 
Priority is always given to botanical and plant extracts over biotechnology as long as they can meet our expectations and  conform  to our commitment to quality and results and as long as they are available in a safe and consistent manner.
 
Each batch of essential oil entering in our production is submitted to testing in order to ensure its perfect condition, its quality and the active concentration of each particle that composes it. It results to the elimination of non-conform or fraudulent batches.
Such events are rare to us as we have been working for years with the best and most reliable producers. However, if such issues arise, it is most often related to the scarcity and high prices of the essential oils. Only very specific and precise analysis material can detect such frauds, hence the highly advanced controls of our Quality Control Department
