Superficial erbium:YAG laser resurfacing of photodamaged skin.
BACKGROUND
Light chemical peels and microdermabrasion have enjoyed recent popularity for the treatment of mild photoaging. However, clinical improvement from these modalities is often minimal from both a patient's and physician's perspective. Erbium:YAG lasers have been effective in treating mild to moderate photoaging, but the need for either regional or general anesthesia, as well as the significant post-treatment recovery period has limited its use.


OBJECTIVE
We sought to utilize a very low fluence approach to erbium:YAG laser resurfacing, with topical anesthesia, to ascertain its efficacy in treating mild to moderate photoaging.


METHODS
A total of 250 subjects aged 28-80 years with skin types 1-4 and mild to moderate facial rhytids were treated with topical anesthesia and subsequently one pass of a 2940 nm erbium:YAG laser, using between 5 and 17.5 J/cm2. In addition, 58 of the treated facial subjects underwent neck resurfacing with fluences between 5 and 15 J/cm2 and eight treated facial subjects underwent upper chest resurfacing at fluences of 5-7 J/cm2. A single treatment was received by 246 subjects; four subjects were treated a second time after a 1-month interval.


RESULTS
Most subjects completely re-epithelialized by 3-4 days; healing time was depth dependent. Most subjects were able to start skin care regimens within 1-2 weeks after the procedure. Results were judged to be excellent in individuals with thin skin and good in subjects with thicker skin.


CONCLUSIONS
One pass of low fluence erbium:YAG resurfacing, under topical anesthesia, was effective for the treatment of mild to moderate photoaging.
