The linoleic acid in gram flour can help significantly remove tan when combined with other detanning ingredients. To create a detan pack for your face, mix two tablespoons of gram flour with one teaspoon of lemon juice and one teaspoon of yogurt. Add a pinch of turmeric and salt and mix all ingredients together to form a smooth paste. Apply the mask to your face, neck and any areas affected by tanning. Let the pack dry on the skin and then rinse with cool water.
