The nanopen is recommended to be used once a week. Depending on your skin composition, you can choose to use the nanopen less frequently if your skin is sensitive or more frequently, but no more than twice a week. You know your skin best so choose what works best for your skin condition. Please note, how often you use the nanopen may also depend on sun exposure. The nanopen shouldn’t be used before high sun exposure.
Please note: the nanopen treatment is not recommended on active acne, moderate to severe eczema, skin conditions that have extreme keloidal tendency, local infection such as herpes and warts and on any open wounds; the nanopen should not be used by anyone receiving anticoagulant therapy, chemotherapy or radiation therapy.
