Plain yoghurt is another one of our favourite ingredients for home remedies for oily skin that has a number of benefits. Yoghurt contains lactic acid, which exfoliates and removes the oil from your skin. All you need to do is to apply fresh yogurt to your face and leave it to sit for fifteen minutes and then rinse it off with water. Yoghurt is quite gentle on the skin, so you could use this treatment every other day.
