Research indicates that LED light therapy can be effective for wound healing and other types of skin damage. In the past, Navy SEALs used LED light therapy to help heal wounds. The treatment led to improvements of more than 40% in musculoskeletal injuries in team members. It also reduced wound healing time. 

According to the American Academy of Dermatology, most people with acne will see an improvement in their symptoms from using LED light therapy, but they should not expect all acne to clear. It is necessary to have several treatment sessions before noticing an improvement in skin appearance. People usually see the best results several weeks after their last treatment. 

It may also be necessary to have follow-up sessions to maintain these results.
