ABSTRACT
Background:
Most data on laser resurfacing have come from studies of people with
Fitzpatrick skin types 1 - 3; however, the world’s population is
comprised mostly of Fitzpatrick skin types 4 - 6, 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 & Materials: The
clinical study included six subjects of Vietnamese origin who underwent
single-depth fractionated CO2 laser resurfacing. The histologic study involved a seventh subject. The MiXto SX®
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&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.
