Brief Summary
The purpose of this study is to assess the efficacy of skin anesthesia using fractional laser assisted delivery of articaine hydrochloride 40 mg/ml and epinephrine 10 µg/ml solution (AHES) compared to standard anesthesia with topical eutectic mixture of lidocaine 25 mg/g and prilocaine 25 mg/g cream (EMLA cream) prior to ablative fractional laser treatment of acne scars and traumatic scars.

Outcome Measures
Primary Outcomes (1)
Pain, as scored on a VAS from 0-10 (0: no pain; 10: worst imaginable pain) at each of both regions.
< 1 minute after AFXL treatment
Study Arms (2)
Region 1
ACTIVE COMPARATORStandard topical anesthesia using eutectic mixture of lidocaine 25 mg/g and prilocaine 25 mg/g cream (EMLA cream) applied two hours before treatment.
Region 2
EXPERIMENTALAnesthesia using articaine hydrochloride 40 mg/ml and epinephrine 10 µg/ml solution (AHES) applied on ablative fractional laser (AFXL) pretreated skin 15 minutes prior to the treatment.
Interventions
Pretreatment at 2.5 mJ/microbeam and 15% density.
Topical application on AFXL pretreated skin 15 minutes prior to the treatment.
Topical application 2 hours prior to the treatment.
