Abstract:
The purpose of this study was to evaluate the histologic difference that occured after trichloroacetic acid(TCA) chemical peel in an animal model that was pretreated with Tretinoin alone or Tretinoin-based combined pretreatment kit. Eight Hartley white guinea pigs were used in our study. The dorsal skin of the guinea pigs was divided into six equal squares(2x2 cm). Upper two areas of these six were not pretreated, middle two areas were pretreated for 4 weeks with Tretinoin alone and lower two areas were pretreated for 4 weeks with Tretinoin-based combined kit. Each guinea pig underwent chemical peel with 50% TCA. The wounded areas were biopsied at post-peeling 3 weeks and 6 weeks. The histology revealed that those animals pretreated with combined kit healed quicker than the animals pretreated with Tretinoin alone. This study implies that if patients are treated with Tretinoin-based-combined pretreatment kit before undergoing chemical peel, the pretreatment time will be shortened.
