Did you know that the humble calamansi fruit can help clear acne? It actually helps in two ways. First, as a regular part of one's diet, it's a great source of Vitamin C which adds to overall health. As a natural laxative, it also helps us rid ourselves of toxins.
Then you can also use the fruit directly on your face by putting some on the infected marks to expedite healing. Don't rub the sliced fruit on your face because that would irritate it more, just dab the fruit on the really angry breakouts after washing your face well.
