Always! Proper preparation of the skin is a must for all procedures and this includes the numbing step. Ample topical numbing solution (4-5% lidocaine) is used prior to any procedure and is usually sufficient for most people. However, for the particularly sensitive, it may be helpful to take Tylenol or acetaminophen ahead of the procedure. Clients are also welcome to come prenumb using an OTC or prescribed topical numbing solution.
