True beauty comes from within, you can cover yourself with as much plastic as you want and there is nothing wrong with that, your life your decision. But if you are not a good person, your perfections will just magnify the ugliness of your intrinsic imperfections.
Even from aesthetic point of view, striving for the beauty of our external shell, there is nothing wrong with it as long as you feel comfortable with yourself. But you have to remember that the colour of your skin does not define beauty, it is a pigmentation of the skin – nothing more nothing less. All shades of people are beautiful. Learn to love and understand yourself before you try to change yourself – and only change for the better that you think will make you happy not someone else.
