|Experimental: S-Caine Peel||
Drug: S-Caine™ Peel (lidocaine and tetracaine topical cream 7%/7%)
S-Caine Peel comprising a 1:1 eutectic mixture of 7% lidocaine and 7% tetracaine was applied topically. A thin layer of the peel (approximately 1 mm in thickness) was applied and remained on the treatment area for 30 minutes (±2 minutes).

Other Name: Placebo
This was a multicenter, randomized, double-blind, placebo-controlled, paired study that evaluated the effectiveness of S-Caine Peel in providing local dermal anesthesia for non-ablative facial laser resurfacing. Patients received a concurrent application of S Caine Peel and placebo for 30 minutes (±2 minutes).
Patients who presented to the study site for a non-ablative facial laser resurfacing and who met study entry criteria were invited to participate in the study. At the screening visit, the study, including potential risks and benefits, was clearly explained to each patient, and written informed consent was obtained. A medical history was obtained including skin type, demographic data, prior and current medical disorders, and the use of concomitant medications. A brief physical examination was performed including taking basic vital signs and examining the skin at the study drug application site. If applicable, a urine pregnancy test was performed. The screening visit could occur on the same day as the procedure visit.
At the procedure visit, patients were randomized to receive a 30-minute (±2 minute) application of S Caine Peel either on the right or left treatment area and to receive a concurrent 30-minute (±2 minutes) application of placebo on the alternate treatment area. The point of reference was always the patient's right and left. S-Caine Peel and placebo were dispensed to cover the treatment area with a uniform thickness of approximately 1 mm. Study drug was applied to the right treatment area first, then concurrently to the left treatment area. Similarly, the study drug was removed first from the right treatment area and then from the left treatment area. Following removal of the study drugs, the investigator or physician subinvestigator evaluated each study drug application site for erythema, edema, blanching or other skin reactions. The right treatment area was evaluated first, followed by the left treatment area.
After the skin evaluations, the laser procedure was performed on the right treatment area, followed by patient and investigator efficacy evaluations for the right treatment area. The laser procedure was then performed on the left treatment area, followed by patient and investigator efficacy evaluations for the left treatment area.
