Successful Treatment of Severe Keratosis Pilaris Rubra with a 595-nm Pulsed Dye Laser

Combination of 595-nm pulsed dye laser, long-pulsed 755-nm alexandrite laser, and microdermabrasion treatment for keratosis pilaris: retrospective analysis of 26 Korean patients

“…Clark et al (7) reported that facial lesions with keratosis pilaris atrophicans demonstrated marked improvement with a 585-nm PDL treatment using a spot size of 5-or 7-mm, a pulse duration of 450-)as and a fluence from 6 to 6.5 J/cm. With the wavelength of 595-nm, Kaune et al (1) presented a patient with keratosis pilaris rubra and ulerythema ophryogenes successfully treated with PDL using a spot size of 7-mm, a treatment fluence up to 12 J/cm^, and a pulse duration of 3-ms. Alcántara González et al (2) also demonstrated remarkable improvement of KP rubra or KP atrophicans faciei treated with 595-nm PDL using a spot size of 7-or 10-mm, a pulse duration of 0.5 or 1.5 ms and a fluence from 5 to 9 J/cm.…”

“…Treatment of KP includes various keratolytics, chemical or mechanical peels, vitamin D3 analogues, topical or systemic retinoids, and laser or light therapy with various clinical outcomes (1)(2)(3)(4). Recently, our study group treated two patients with KP on the extremities with three sessions of a 595-nm pulsed dye laser (PDL), a long-pulsed 755-nm alexandrite laser, and microdermabrasion combination therapy with marked clinical improvements (5).…”

“…In the previous study, we used PDL, which has been reported to be effective in KP rubra and KP atrophicans faciei, for the treatment of KP lesions with nonpurpuragenic fiuences to minimize downtime and to avoid possible postlaser therapy dyschromias (1,2,5).…”

“…Keratosis pilaris (KP) has been presented as small keratotic follicular papules with or without surrounding erythema, which mainly involves the extensor aspects of the upper arms, anterior thighs, face, and buttocks (1,2). Treatment of KP includes various keratolytics, chemical or mechanical peels, vitamin D3 analogues, topical or systemic retinoids, and laser or light therapy with various clinical outcomes (1)(2)(3)(4).…”

Caso para diagnóstico

“…Currently, the Pulsed Dyed Laser of 595nm is a therapeutic option to attenuate hyperpigmentation and erythema. 9 Erythromelanosis follicularis faciei et colli (EFFC) is a rare disease for some authors but others consider it an underdiagnosed entity. Due to rarity or to underdiagnosis, less than 50 cases were described.…”
