Melasma Cure Using Lemon Juice: Lemon juice is highly acidic in nature, which helps to peel away the top layers of the skin, causing the brown patches to fade. Squeeze out the juice of a few lemons and store it in a container in your refrigerator. If needed, you can add equal amounts of rose water and glycerin to the lemon juice.
This helps to dilute the juice since pure lemon juice may be little harsh on sensitive skin. Use this mixture daily on the affected parts of the skin before going to bed.
Avoid using lemon juice during the day as exposure to the sun can further darken your dark patches.
