In other words, it removes toxins from the body and cleanses thus creating healthy looking skin.
Pluses: you will definetely see a difference in your skin when taken regularly. I had to take it for 3 months to see a difference. I had a pale skin before i took Safi. But after 3 months of taking safi, my skin cleared and got brighter.
