About

This study is being done to answer the question: Do STAR particles (tiny pieces of ceramic with small spikes) help numbing gel (a gel that helps you feel less pain) work more quickly to provide local anesthesia or numbing in a specific area? Research participants will provide feedback on how quickly the STAR particles with the numbing gel can provide anesthesia. Participants will report their sensation at either 10 or 20 minutes after application of the numbing gel.

Full description

This study aims to find out if the combination of STAR particles with numbing gel can deliver anesthesia faster than applying the gel by itself. STAR particles are very small particles with microneedles on the surface that can increase and create small punctures in the skin. The small punctures should allow for the numbing gel to work more quickly and allow the area to become numb more quickly.

After pretreatment with STAR particles (applied to the right or left arm) and aloe gel (used as a control condition in the contralateral arm) a numbing gel will be applied. A Pin-Prick test will be performed to evaluate local anesthesia from the numbing gel; half the participants will be evaluated 10 minutes after application of the numbing gel and the other half will be assessed 20 minutes after the numbing gel is applied. The study team will also assess pain after needle insertion and measure how much water is being lost from the skin using a device called a Vapometer before and after the STAR particle and aloe gel applications. Participants will have follow-up calls 24 hours and 1 week after the visit to ask about any changes to the skin where the STAR particles were applied.
