You have seen many fair people with yellow teeth. The contrast makes them look really bad, does it not? The main ingredient is Applephenon which was discovered in Japan. It is extracted and processed from the skin of a special breed of unripe Green Japanese apples. It reduces melanin production safely to make skin fairer and has a teeth whitening effect as well. Fairen also has Marine Collagen from England to make skin younger. It is well known that Collagen is what keeps skin young and elastic and that is how Fairen has an anti ageing effect. Applephenon coincidentally also prevents dental cavities and bad breath.
