Milk, enriched with enzymes as it is, is a gentle whitener. It also contains moisturising properties by balancing out the more astringent qualities of lemon juice that tend to dry out your skin. To being with, draw a bath of warm water in a tub. Add a cupful of milk
(not fat free milk) and squeeze in the juice of one lemon into the water. Soak in this gentle mix for 20 minutes, before rinsing it off. You can try this remedy once a week.
