Laser peel: facial rejuvenation with a superficial erbium:YAG laser treatment.
BACKGROUND
Facial rejuvenation is a popular procedure to temporarily mask the effects of aging. Most patients desiring this treatment are younger and want improvement without any down time. This study was conducted to evaluate the use of Er:YAG laser as a facial rejuvenation tool.


METHODS
The full faces of 18 volunteers were treated with an Er:YAG laser using a fluence of either 5 or 10 J/cm2. All volunteers applied EMLA cream (lidocaine 2.5% and prilocaine 2.5%) two hours before the procedure and were treated with a single pass using a pulse duration of about 300 microseconds. Follow-up visits were made in order to evaluate the degree of discomfort, erythema, swelling and improvement in skin aging. Skin biopsy was performed in one volunteer before and two hours after EMLA application, although preceding laser treatment.


RESULTS
Most volunteers experienced moderate discomfort during the treatment. There was mild to moderate erythema and mild swelling. The improvement in general skin appearance, actinic bronzing and photo-damage was mild to moderate. The microscopic evaluation of pre-laser treated skin two hours after EMLA application was suggestive of increased water content in the dermis.


CONCLUSIONS
The Er:YAG laser is an effective and safe tool for facial rejuvenation. With a superficial treatment, resolution of intense erythema is fairly rapid, averaging two to three days. The improvement, however, is mild compared to full laser skin resurfacing (LSR).
