Keratosis pilaris atrophicans: treatment with intense pulsed light in four patients.
BACKGROUND
Keratosis pilaris atrophicans (KPA) is a group of disorders characterized by erythematous keratotic papules followed by atrophy on the face. The treatment is often unsatisfactory.


METHODS
Four white women, with ages ranging from 14 to 20 years, were treated with an intense pulsed light (IPL) system with a cut filter of 570 nm. The power density was between 40 and 47 J/cm(2), divided into two pulses of 3 ms, with a delay between both of 20 ms. Patients received five to nine sessions.


RESULTS
Clinical improvement was noted in all patients, with a reduction of erythema in treated areas of between 75% and 100%. Treatment was well tolerated and no adverse reactions were observed. After a follow-up of 10 months no recurrence was observed. In addition, in parallel mode to erythema improvement, a reduction of roughness was observed.


CONCLUSIONS
Our results suggest IPL should be considered as a safe treatment option in patients with KPA.
