from the Ren website :
REN pioneered the concept of Clean Bio Active skincare. Skincare that is free from skin unfriendly chemicals and yet at the cutting edge of cosmetic science in its use of 100% natural Bio actives. REN has five key principles:
Right Ingredients: We make Clean Products that don't contain skin-unfriendly ingredients including: Synthetic fragrance, petrochemicals, sulfate detergents, synthetic colours, animal ingredients and parabens. In addition, REN products do not contain potential irritants including: glycols and diglycols (such as propylene glycol), PEG's, PPGs, urea, D.E.A, T.E.A, PABA and other synthetic sunscreens, aliphatic alcohols/hydrocarbons, phthalates, fumarates, amines, alkanolamines, synthetic AHAs/BHAs, polyacrylamide, metacrylate, elastomer, poloxamer, styrene, vinyl, polyquaternium, synthetic chelating agents, nylon, nitriles, nitrates, nitrosamine releasers, bromates, fluor, aluminum and alumina.
Right Science: REN’s aim is to pioneer new ways of applying the latest discoveries in bio active technology to produce skincare formulations that boost the skin’s natural processes of protection, repair and renewal. Bio science is key to making products that are increasingly effective in helping achieve and maintain beautiful, healthy skin.
Right Product Experience: This is our pleasure principle. It matters because it can change your world. You wake up, use REN and the world is just a 5% nicer place to be. So you eat a healthier breakfast, choose clothes that are 5% nicer, you walk 5% taller and smile 5% more, as a consequence people notice you 5% more and are 5% nicer to you...it can be a magically virtuous circle.
Right Environmental Impact: We do our bit to minimise our use of the world’s limited natural resources. We donate a minimum of 2.5% of our profits to campaigns that promote a better environment and a better life for those less fortunate than ourselves.
Right Attitude: We believe a principle is a principle even if it costs money. We believe we reap what we sow. We prefer goodwill to suspicion, humour to gravitas, informality to formality. We welcome difference.
