BACKGROUND: Keratosis pilaris (KP) is a common disorder of keratinization with different therapeutic modalities; however, none of them is completely satisfactory.
OBJECTIVE: Assess and compare the efficacy of trichloroacetic acid (TCA) 20% and long-pulsed 1,064-nm Nd:YAG laser in the treatment of KP.
MATERIALS AND METHODS: Twenty patients with symmetrically distributed areas of KP were enrolled in this study. In each patient, 2 symmetrical KP areas were randomly assigned to receive 4 sessions of either long-pulsed Nd:YAG laser or TCA 20%. Clinical evaluation by Investigator Global Assessment (IGA) was done by 2 blinded physicians after treatment. Dermoscopic assessment was done at baseline and at the end point of the study.
RESULTS: Investigator Global Assessment of laser-treated area showed that 2 patients (10%) had moderate improvement, 10 patients (50%) had marked improvement, and 8 patients (40%) had excellent improvement. Investigator Global Assessment of TCA-treated area showed that 9 patients (45%) had marked improvement and 11 patients (55%) had excellent improvement. Dermoscopic score of KP showed a significant reduction with both modalities. The IGA and reduction in dermoscopic scores were comparable between the 2 modalities.
CONCLUSION: Both long-pulsed 1,064-nm Nd:YAG laser and 20% TCA are effective in the treatment of KP.
