Grading scale: collagen (+: not enough collagen; ++: enough collagen; +++: keloid formation); epithelia (+: thin; ++: thick; +++: thick enough); inflammation (+: few scattered lymphocytes; ++: enough lymphocytes); vascularization (+: few blood vessels; ++: many blood vessels); fibroblast (+: less dense; ++: denser). PCFHE: P. clappertoniana fruit husk extract; SSD: silver sulfadiazine.
