Comparison of Er:YAG laser, short pulse-duration pulsed dye laser, and long pulse-duration pulsed dye laser in treating sebaceous hyperplasia

Background: Patients of sebaceous hyperplasia (SH) usually seek treatment due to cosmetic concern. A few nonsurgical ablative devices are effective in treating SH, including carbon dioxide laser and erbium-doped yttrium aluminium garnetlaser (Er:YAG) laser. But these options bear the considerable risk of postoperative discoloration and scar formation. Pulsed dye laser (PDL) has been reported effective in treating SH. However, only short pulse-duration PDL (SPDL) has been used in previous studies.
