Quercetin & Oak light texture cream for oily skin

The Korres Research & Development Lab in cooperation with the National Hellenic Research Foundation has studied antiageing at cellular level through the function of proteasome, an essential shield mechanism of cell proteins like collagen and elastin. Highly-effective flavonoid Quercetin activates proteasome to prolong skin cell lifespan and act as a restorer on all ageing signs.


In vitro studies on fibroblasts [epidermal cells] prove Oak derived Quercetin's impact on vital biological ageing markers:

Up to 39% reduction of free radicals within cells. Repairing activity on already aged cells which revert to the young cell phenotype [photographed under the microscope]

Ιn vivo clinical studies: *

  • 91% of users reported more matte/less oily skin
  • 94% of users reported visible wrinkle reduction
  • 97% of users reported significant skin texture improvement [softer and more even, compact skin]
  • 100% of users reported significant increase in skin elasticity

* Self-evaluation test/8 weeks of use

In vitro results: Quercetin & Oak skincare stimulates cell growth and protein synthesis within 24 hours.

Innovative Study

The Korres Research & Development Lab has collaborated with the Institute of Biological Research and Biotechnology [IBRB] at the National Hellenic Research Foundation and the University of Athens on a five year primary study of the antiageing mechanisms at cellular level. The study focused on the function of the proteasome, an essential shield mechanism of cell proteins like collagen and elastin and its activation to defend and prolong skin cell lifespan. Following the Nobel-awarded discovery of the ubiquitin-proteasome system in 2004, IBRB’s Molecular and Cellular Ageing Programme is one of the world’s most significant research groups working in the Proteasome and Human Ageing field with a number of globally-recognised publications on this subject.


The proteasome is one of the vital mechanisms that protect young cell phenotype. It acts as a catalyst within cells, breaking down and eliminating damaged skin proteins. It recruits therefore the building blocks [amino-acids] needed to create healthy essential proteins, like collagen and elastin. However, proteasome activity has been proven to decrease as people age, leading to a lower-formation rate of new healthy proteins. When the proteasome activity is boosted, healthy proteins are formed, helping the skin regenerate.


The study focused on the in vitro performance [on cultivated fibroblasts] of over 50 powerful natural antioxidants and their impact on proteasome activity. Among these natural actives examined, the use of flavonoid Quercetin [Oak derived] proved to have an overall excellent performance in boosting proteasome activity and cell regeneration, in relation to the essential ageing bio-markers.
