That homemade face packs and/or expensive readymade creams can lighten your skin colour and turn you into a beautiful swan...IS A LIE. Your skin colour is determined by melanin and no amount of topical applications(however natural, expensive, or whatever else) can change that!
So if you are seriously(stupidly) looking for ways to become fair...and that's why you are here, reading my collumn. Sorry to disappoint you! It is impossible to lighten the colour of melanin. And before you leave, "brown(black even) is beautiful"!
Melanin is the dark brown or black pigment that gives humans their hair, eye, and skin colour. In India, fair skin is still regarded as the epitome of beauty! Little wonder then that the industry for fairness cosmetics is a million dollar business, there.
Even very educated people in India still have a strong colour complex! When it comes to beauty, it seems that most people, in the sub-continent ,will still see skin colour first and then the complexion and features.
Complexion refers to the natural colour, texture, and appearance of the person's skin, particularly that of the face. But in India, the term is often used to refer to skin colour alone. One look at Indian matrimonials is enough to prove this point.
"...wanted bride of fair complexion..." or "...23 years old, fair..." almost every ad includes the term fair skin! Looking through these ads, I wonder whether it is something to do with the hangover from British Raj(the white skin syndrome) that Indian's have still not completely recovered from?!
Even here on EC, writing a column on fairness is a great way to get views! It is! I have already got a total of 40 odd views for one such column on how to prepare a fairness and firming face mask at home. It was a recipe shared by an Indian friend (and it does work beautifully on the skin!).
But to believe that any face pack, homemade or otherwise can reverese your skin colour, is a MYTH! People wake up. What a face pack can do (at best!) is help remove sun tan, and tone your skin to a certain extent. That's about it! If you want to change your skin colour the only option is surgery!?
