In summary, forced cold air cooling has been found to reduce pain during laser treatments,2,3 and we have found similar efficacy during injections with dermal fillers and botulinum toxin. Unlike traditional pain-reduction modalities that may be associated with allergic reactions or adverse effects,4 this novel method of pain reduction reduces intraoperative pain associated with these injection techniques with minimal risk. Seven of nine randomly sampled patients in our practice noted less pain during injection with use of the forced cold air cooling device. We are currently performing a larger split-face trial to quantify pain reduction with forced cold air cooling associated with these injections.
