Acne erythema consists of telangiectasia and erythematous papules, without a comedo, which occurs as a result of inflammatory acne. Moreover, although acne erythema is common in acne patients, no satisfactory medical or surgical treatment is available for this condition. Some acne erythema lesions may improve with time, but the persistent acne erythema, which is experienced by most patients, is cosmetically unacceptable and leads to frustration and psychological distress.

Up to the present time, there have been several studies on the clinical efficacy of different laser modalities for acne treatment. Pulsed dye laser (PDL), 585 or 595 nm, has been demonstrated as one of the effective treatment options Another laser long-pulsed neodymium: yttrium-aluminum-garnet (Nd:YAG) laser with 1064 nm has been commonly used for skin rejuvenation. Nevertheless, the efficacy of this laser for acne treatment has been shown in some studies and case reports. The therapeutic effect on acne lesions is believed to be mediated by the selective photothermolysis of vessels, the upregulation of TGF-β, the reduction of interleukin-8 (IL-8) and Toll-like receptors-2 (TLR-2), and the thermal destruction of sebaceous glands.

Isotretinoin remains the mainstay of acne treatment. No doubt, the side effects of this effective drug holds physicians back from jumping to prescribe it. Recent data suggested that lower doses (0.25 mg/kg/day) may lead to fewer side effects. and fewer flares. Clearing the use of oral isotretinoin in combination with other procedures has expanded our therapeutic options to obtain better control.
