Colladeen® Derma Plus contains one of the highest levels of anthocyanidins (plant flavonoids or PCOs) at 320mg per two tablets from extracts of grapeseed and bilberries, alongside green tea leaf and a full 6mg of pure free-form lutein.
Research has shown all of these to be powerful antioxidants helping to block the action of the damaging effects of free radicals generated by sunlight.
Additionally anthocyanidins have been identified as having an important role in maintaining the health of collagen, which is a protein responsible for the structure and firmness of skin.
