Another exclusive feature of Restylane KYSSE is the inclusion of lidocaine – a numbing agent. Many patients describe the sensation of the injections as a mild insect bite. Still, if you are sensitive to sensation (as many people are when it comes to the lips), Dr. Farber can apply a topical numbing cream, which nullifies any discomfort. The lidocaine included in the Restylane KYSSE formula will massively reduce any pain after the treatment and during the short healing phase.
