It's upgraded on our current stainless steel torch red light therapy but with two buttons . One button is for red and near infrared leds diode and another one for blue led only . You can press both buttons on for all led on at the same time as well.
Red and near infrared led is ideal for pain relief and wounds healing while blue led is ideal for acne treatment and anti-inflammatory . Recommend for these one who want to do business with a hot sales product but with a different solution so you can avoid the fierce competition.
