%X Background: Most data
on laser resurfacing have come from studies of people with Fitzpatrick </span><span style=\"line-height:1.5;\">skin types 1 - 3; however, the worldĄŻs population
is comprised mostly of Fitzpatrick skin types 4 - 6, </span><span style=\"line-height:1.5;\">which are more
susceptible to post-inflammatory hyperpigmentation (PIH). Objective: For the
purpose of expanding the expertise of plastic surgeons treating patients with
darker skin types, this study examined the incidence of PIH in Asians who
underwent laser resurfacing, including a histologic arm on fractional ablative
resurfacing. Methods &amp; Materials: The clinical study included six subjects
of Vietnamese origin who underwent single-depth fractionated CO</span><sub>2</sub><span style=\"line-height:1.5;\"> laser resurfacing. The histologic study involved a seventh subject. The MiXto
SX&lt;sup&gt;<sup></sup><span style=\"background-color:#FFFFFF;\">&amp;reg;&lt;/sup&gt;</span></span><span style=\"line-height:1.5;\"> laser with a new scanning handpiece was
used, along with magnifying loupes to assess ablative depth after each of three
laser passes performed. Photographs were taken at various postoperative
intervals. Results: All six clinical subjects showed cosmetic improvement in
skin texture and tone with no post-inflammatory hyperpigmentation. In the
histologic study, H&amp;E stained sections revealed uniform diathermy. Conclusion:
It is possible to significantly reduce PIH in darker skinned subjects through
use of a new scanning handpiece and a technique using loupes to assess the
depth of ablative resurfacing. The histologic study confirms these findings.
