AvanDermNu An exfoliating agent is also part of good skin care; exfoliating simply removes the top layer of skin and with it some dead skin cells and other elements that make your skin look unhealthy and sallow. As with cleaning you don't want to exfoliate too often as this will also irritate the skin. A good skin care routine usually means exfoliating once or twice per week; if you do this any more often than this you want to be sure to use a very gentle product. http://jackedmuscleextremeadvice.com/avandermnu/
