1. Lemon juice:
Lemon juice is a boon that just keeps giving – aside from having amazing effects on your digestion, energy and teeth, lemon juice has also been used for many years for skin whitening. It contains properties that mildly bleach your skin and exfoliate its top layer. Pure lemon juice can be very strong for the skin, so add one part water to one part lemon juice and dab it all over your face with a cotton pad. Wash it with warm water 15 minutes later. A few important things to remember – only apply this mixture 2-3 times a week, always moisturise afterwards and wash it off thoroughly before going out in the sun.
