Achieving esthetic improvement in a rare case of facial blaschko-linear lichen planus using 1064 nm Q-switched neodymium: Yttrium-aluminium-garnet laser and microneedling pen

Lichen planus (LP) affects between 0.5 and 1% of the population. Linear LP accounts for <0.2% of LP cases. Linear LP of the face is even rarer, with only a handful of cases. Linear facial LP follows Blaschko’s lines, usually along the mandible, has follicular localization and leaves long-standing pigmentation and atrophy. There is a paucity of data for the treatment of LP esthetic sequelae, more so for facial linear LP in darker skin types with atrophy. Most treatments are attempted to stabilize the spreading of the disease and limit its progression but do not successfully address esthetic pigmentation and atrophy. Our case is an Indian woman with isolated facial linear LP clinically who was successfully treated for esthetic sequelae with 1064 nm Q-switched neodymium: Yttrium-aluminiumgarnet laser and microneedling pen without relapse even after 1 year.
