Cheap and easy. All you need is Lime fruit and some sugar,white or brown,all good!
Put lime fruit in the microwave for 30seconds.
Cut your lime in half and dip the fleshy surface of one half in the sugar so the granules stick to it. Use this to rub on the face gently in circular motion.
Do not apply too much pressure but repeat circular motion around the face for 3-5 minutes, then rinse off with luke warm water.
Do this 3 times each week and you'll see results.
