Ok...OP here's the issue with you posting this many people who live in England are white do not understand the concept of skin whitening.
It seems ridiculous at first, OMG they are doing that who are they Michale Jackson etc.
Then when you point out the numerous tanning salons, and tanning products on the shelves they notice the hypocrisy. Why don't white people like their white skin? Why do they want to paint themselves like a wall, or permanantly damage their skin under tanning beds?
There are skin whitening products that are sold in supermarkets just like Johnsons Tanning Cream that gently lighten your skin, however, they are not sold in this country.
Just type in Nivea Whitening Cream on google. However, i doubt you could source any.
