Milk or milk cream can also be used for treating sun tanned skin.
Put a small amount of milk in a bowl and add a pinch of turmeric and some lemon juice. Apply this solution on the affected areas and allow it to dry completely. Then wash it off with water. This will give you an instant relief from a sun tan.
You can also soak a pinch of saffron in fresh milk cream overnight. In the morning, stir it well and apply it on the affected skin areas. This will lighten your complexion and make your skin glow.
