Abstract
Introduction

Acne vulgaris is a multifactorial disease of the pilosebaceous unit characterized by the development of inflammatory (papules, pustules, cysts) and/or non inflammatory lesions (open and closed comedones) that may progress to scars. The increase of bacterial resistances, adverse effects and teratogenicity of retinoids and lack of response to usual therapies have led to investigate new therapeutic alternatives for acne.

Material and method

We studied 36 patients with mild to moderate acne vulgaris. We performed treatment every 4 weeks using pulsed dye laser therapy with a wavelength of 585 nm and pulse duration of 350 microseconds.

Results

At twelve weeks of treatment a decrease of 27% of non inflammatory lesions and of 57% of active lesions was observed. Treatment was well tolerated and considered positive, in terms of healing, in 25 patients.

Conclusions

Pulse dye laser therapy mainly improves inflammatory lesions of acne with few adverse effects.

Resumen
Introducción

El acné vulgar es una enfermedad multifactorial de la unidad pilosebácea caracterizada por la aparición de lesiones inflamatorias (pápulas, pústulas, quistes) y/o no inflamatorias (comedones cerrados y abiertos) que pueden evolucionar al desarrollo de cicatrices. El aumento de las resistencias bacterianas, los efectos adversos y teratogenicidad de los retinoides y la falta de respuesta a tratamientos habituales llevan a la necesidad de investigar nuevas opciones terapéuticas para el acné.

Material y métodos

Estudiamos a 36 pacientes con acné vulgar de grado leve a moderado. Realizamos tratamiento cada 4 semanas utilizando un láser de colorante pulsado de 585 nm de longitud de onda y 350 microseg de duración de pulso.

Resultados

A las doce semanas de tratamiento se observa descenso del 27% de lesiones no inflamatorias y de un 57% de lesiones activas. El tratamiento fue bien tolerado y considerado como positivo, en cuanto a curación, en 25 pacientes.

Conclusiones

El láser de colorante pulsado mejora principalmente las lesiones inflamatorias del acné con pocos efectos adversos.
