The laser therapy for pain relief uses proprietary multi-source technology and successfully manipulates the interaction between light, laser and magnetic energy fields to achieve the desired penetration in the target tissue. The pulse penetrates an area of 0 - 13cm (4 - 5 inches) deep into the target tissue and stimulates the muscles cells while preserving the overlying epidermis. The results are imminent. The relief is felt rapidly. It is FDA approved.
