Numb step 2 gel designed to work within the skin. The gel works by numbing inside the skin for a short time and is applied, where appropriate, before certain Plasma Pen procedures to help prevent any pain in the skin although feelings of pressure and touch will likely remain. You must check your local authority / country status and any other relevant authority before purchasing, using or applying any topical anaesthetic, even over the counter, MHRA approved products. Regardless, you must complete a full consultation and make yourself fully aware of any contraindications and/or medical conditions which could prevent the safe use/application of any topical anaesthetic, no matter how mild, such as there being an allergy to any of the ingredients. You must follow all training guidelines in terms of the safe application of topical anaesthetic. Topical anaesthetics such as LMX and EMLA contain up to 5% lidocaine and/or prilocaine. Emla should never be applied to the upper eyelids due to the consistency . Only fully certified Plasma Pen by Louise Walsh International technicians may purchase topical anaesthetics and we restrict sales in certain territories.
