Dermaplaning is usually performed every three to four weeks. It is good to have the skin complete its normal rejuvenation cycle, which is thirty days, before going back and having the treatment done. The procedure generally will remove between two to three weeks of dead skin from the facial area. People who suffer from acne or have excess oil should not have dermaplaning performed.  The reason why you want to avoid this procedure is because if the hair is removed from the area, the oils may cause bacteria growth which could lead to acne breakout
