• In order to achieve the desired effect with your skin care session, make sure you use the most nutritive citrus fruits as lime, grapefruit as well as lemon and orange. To prepare the soothing paste, all you have to do is add either 2 spoons of the juice of all these citrus fruits into a medium-sized bowl or restrict the use only to one of the fruits. If you decide to use only one fruit type, make sure you put at least 4-5 tbsp of juice into the bowl, then mix it with 2 tbs of wheat flour. Control the texture of the paste and make sure it can be applied on your face without any difficulties. Leave the facial on for at least 15-20 minutes, then wash it off with lukewarm water.
