Dr Numb with 5% lidocaine. A safe and pure numbing cream that does not interfere with any kind of permanent ink, tattoo ink or piercing process. 1. Wash the area receiving tattoo or microblading with soap and water. Dry area completely. 2. Apply a thick amount of numbing cream to the area and rub in thoroughly. 3. After rubbing into the skin, apply a 2nd heavy layer of cream (1/8″ or 3-5 mm thick) over the area. 4. Cover the cream with plastic wrap (saran wrap) and keep warm. The heat under the plastic wrap helpsactivate the cream and keeps the cream from drying out. 5. Leave cream and wrap in place for 2 hours before procedure. For long procedures lasting hours over large areas; apply numbing cream over the entire work area, then remove in sections as procedure progresses. 6. Skin typically remains numb for 1 – 4 hours once cream is removed from numbed skin depending on skin type and location on body.
