Isotretinoin is the background treatment of cases of severe acne. Side effects associated with the standard 0.5\u20131\u2009mg\/kg\/day dose decrease patient compliance. Pulsed dye laser (PDL) was proved effective in the management of inflammatory acne. The focus was to evaluate the efficacy of combining low\u2010dose isotretinoin (0.25\u2009mg\/kg\/day) with PDL in comparison with the standard higher\u2010dose isotretinoin (0.5\u2009mg\/kg\/day) as monotherapy for the management of acne vulgaris.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design\/Materials and Methods<\/jats:title><jats:p>The current prospective randomized comparative study included 46 acne patients, who were randomly divided into two groups. The first (ISO\/PDL group) was treated with oral isotretinoin (0.25\u2009mg\/kg\/day) and five sessions of PDL. The second (ISO group) was treated with oral isotretinoin (0.5\u2009mg\/kg\/day). The physician's clinical assessment was done by three blinded dermatologists using quartile scale score and erythema score at baseline, 3 months, and 6 months and global acne grading system (GAGS) at baseline and 6 months. Patient satisfaction was assessed using the Cardiff Acne Disability Index (CADI).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Both groups showed a significant improvement in all assessed parameters compared with baseline at 3 and 6 months. Comparing both groups together, the ISO\/PDL group showed a statistically significantly greater improvement regarding all parameters at both assessment times. Regarding adverse events, six patients (26%) suffered from flare in the ISO group versus none in the combined group. Dryness was encountered in 20 patients (86%) in the ISO group versus five patients (21%) in the other group. The ISO\/PDL group received significantly less cumulative isotretinoin dosage (48.7\u2009\u00b1\u20095.7\u2009mg\/kg) in comparison to the ISO group (100.4\u2009\u00b1\u20093.1\u2009mg\/kg) (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The current study offers a new collaboration between two well\u2010studied and established treatment modalities leading to a harmony of therapeutic synergism while minimizing the risk of side effects.
