If you do want to become lighter in appearance then it is something you should not take lightly as you could cause damage to the skin. You should be happy with the skin you have but if you want to become fairer then there are number of methods including using acidic compounds such as lime or lemon juice.
As these are high in alkaline and extremely acidic you can perhaps gently rub this on your skin with a cloth but please be warned this is not encouraged and you should consult a specialist before trying this.
Other things which might aid a lighter skin appearance include turmeric and honey which act as natural bleach agents.
This is because they will be able to remove a darker tan and ensure your skin looks fairer. Some also look at applying cucumber juice onto dry or sensitive skin as well as oily complexions because this helps people obtain a fairer complexion.
Another trick is to put on a melange of lemon juice and honey onto the entire face and body. All you then need to do is let it set and leave for around fifteen minutes before washing off.
You can do the same thing with a mixture of lemon and cucumber as well. If you have a lot of body hair you can reduce the dark complexion by applying yoghurt to the body to encourage a lighter look or you can simply get it waxed off on a regular basis.
Some have even talked about providing beetroot or radish juice in order to obtain a lighter appearance due to the acids in these vegetables. But before sampling these remedies do ensure your skin is up to the task in hand and is blemish free.
