Laser and light treatments

Various laser and light modalities have been utilised in the treatment of acne. The best-known light therapy is blue light, which is thought to target Propionibacterium acnes. However, treatment with this technique has produced inconsistent results. [53] [54] [55] Treatment with the pulsed dye laser has also produced inconsistent results. [56] [57] These therapies are still not routinely prescribed, and more research is needed to evaluate their effectiveness and to determine any long-term adverse effects. [58] [59] There are various laser treatment options, both ablative and non-ablative, that may be used to treat residual acne scarring. [60]
