Wound healing refers to a complex biological process in the human body that is achieved through four phases: hemostasis, inflammation, proliferation, and remodeling. The proper sequence and time frame of all four phases are required for a wound to properly and successfully heal.
Many different factors can interfere with one or more phases of this process, thus causing improper or impaired wound healing. Some of these factors include oxygenation, infection, age and sex hormones, stress, diabetes, obesity, medications, alcoholism, smoking, and nutrition.
One effective treatment for wound healing is LLLT. While more studies need to be conducted, previous ones on rodents and smaller studies on humans showed that laser therapy resulted in enhanced wound healing. When it comes to how to treat wounds, the data indicate that LLLT is effective for wound contraction of partially thick wounds.
