Interventions included photodynamic therapy (PDT; 5 RCTs), infrared lasers (4 RCTs), broad\u2010spectrum light sources (3 RCTs, 1 CT), pulsed dye lasers (PDL; 2 RCTs, 1 CT), intense pulsed light (IPL; 1 RCTs, 2 CTs), and potassium titanyl phosphate laser (1 RCT). The randomization method was mentioned in 6 of 16 RCTs, and one trial described adequate allocation concealment. Most trials were intraindividual trials (12 of 19), which applied blinded response evaluations (12 of 19) and assessed a short\u2010term efficacy up to 12\u00a0weeks after treatment (17 of 19). Based on the present best available evidence, we conclude that optical treatments possess the potential to improve inflammatory acne on a short\u2010term basis with the most consistent outcomes for PDT [up to 68% improvement, aminolevulinic acid (ALA), methyl\u2010aminolevulinic acid (MAL) and red light]. IPL\u2010assisted PDT seems to be superior to IPL alone. Only two trials compare optical vs. conventional treatments, and further studies are needed. Side\u2010effects from optical treatments included pain, erythema, oedema, crusting, hyperpigmentation, pustular eruptions and were more intense for treatments combined with ALA or MAL.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion\u2002<\/jats:bold>\n                    Evidence from controlled clinical trials indicates a short\u2010term efficacy from optical treatments for acne vulgaris with the most consistent outcomes for PDT. We recommend that patients are preoperatively informed of the existing evidence, which indicates that optical treatments today are not included among first line treatments.\n
