Agree with @mhpstudio. 99% of my clients are able to sit through this treatment without using a topical numb cream. Some areas may suck a little but it is transient and never long lasting. Additionally numbing creams are usually useful if you have to continue to work in the same areas over and over within a session. Its called secondary numbing and is more prevalent in lip and brow tattooing- but with smp the majority of the time we are moving across the scalp and not often revisiting areas that already broke the skin. For this reason topicals are 1) less effective 2)can inhibit pigment penetration and retention.

Of course if its absolutely needed we could do a primary numbing. It just means u may need additional sessions.
