COMPARATIVE EVALUATION OF LONG PULSE ALEXANDRITE LASER AND INTENSE PULSED LIGHT SYSTEMS FOR PSEUDOFOLLICULITIS BARBAE TREATMENT WITH ONE YEAR OF FOLLOW UP

<b>Background:</b> Existing remedies for controlling pseudofolliculitis barbae (PFB) are sometimes helpful; however the positive effects are often short lived. The only definitive cure for PFB is permanent removal of the hair follicle. <b> Aims:</b> Our aim was to compare the efficacy of the Alexandrite laser with the intense pulsed light system in the treatment of PFB and to follow up the recurrence. <b> Methods:</b> Twenty male patients seeking laser hair removal for the treatment of PFB were enrolled in this study. One half of the face was treated with the long-pulse Alexandrite laser and the other half was treated with the IPL system randomly. The treatment outcome and any complications were observed and followed up for one year. <b> Results:</b> All patients exhibited a statistically significant decrease in the numbers of papules. Our results showed that the Alexandrite-treated side needed seven sessions to reach about 80&#x0025; improvement, while the IPL-treated side needed 10-12 sessions to reach about 50&#x0025; improvement. During the one year follow up period, the Alexandrite-treated side showed recurrence in very minimal areas, while the IPL-treated side showed recurrence in bigger areas. <b> Conclusions:</b> Our results showed that both systems might improve PFB but Alexandrite laser was more effective at reducing PFB than IPL
