Official title
A Double-Blind, Randomized, Split-Face Comparison Trial on Topical Anesthetic Agents Prior to Fractional Skin Resurfacing
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research study is to test which topical anesthesia: LMX4 (Lidocaine 4%) or BLT (Benzocaine 20%, Lidocaine 6%, and Tetracaine 4%) is more effective in reducing discomfort during treatment with the Fraxel DUAL 1550/1927 (Solta Medical, Hayward, CA). No studies have been done on the effectiveness of LMX4 versus BLT using the Fraxel DUAL, although individually LMX4, BLT, and the Fraxel DUAL have been studied extensively. The hypothesis is that there will be no clinical difference between the two topical anesthetics.
