Derma Numb Spray is a topical numbing agent best used towards the end of a tattoo procedure on broken skin. It’s great for large tattoos on pain-intolerant clients or assist you, the artist, in completing the final touches on a client that’s had enough. When compared to other anaesthetic products, this pain relieving spray contains a moderate dose of active ingredient, Lidocaine, at 4%. For a complete pain relief system, use Derma Numb Spray in conjunction with Derma Numb Gel. The Gel is applied one hour before the session on unbroken and the spray is applied during the session.
