**1. Introduction**

The term low‐level laser therapy (LLLT) is broadly defined as the therapeutic benefit of lasers. After Professor Mester from Hungary first revealed the therapeutic importance of lasers, different wavelengths of continuous wave (CW) LLLT have been shown to promote healing in skin from healthy humans and animals, as well as a number of experimental pathological

cases. Different LLLT protocols have been widely used in numerous medical situations with the intent to accelerate the regenerative processes of tissues.

In this review, the author characterized eligible papers into in vivo and in vitro experimental studies and clinical trials that evaluated the use of LLLT on skin wounds for promotion of healing. The author conducted an electronic search of scientific peer reviewed papers in the PubMed database of English language studies published from 2004 to 2016 with the keyword "low‐level laser therapy." As inclusion criteria, the author chose articles with availability of access to the full text. This review intended to show the positive effects of LLLT on healing of skin wounds, diabetic foot ulcers, and burns. Initially, the author introduced wounds, ulcers, and burns and showed their importance. Next, a number of important related papers in the field were reported.
