Dermaplaning can be performed every 3-4 weeks or after the skin has completed its next regeneration cycle. Dead skin cells must accumulate again, and the vellus hairs (peach fuzz) must regrow in order for it to be effective. Dermaplaning treatments can be performed only once if you want radiant skin for a special event, or you can do them once or twice a month in order to maintain radiant-looking skin.
