Red and near-infrared light therapies are effective for improving skin health and appearance, potentially by increasing vascular flow.

“if somebody decides to do phototherapy the use of phototherapy that involves long wavelengths of light so red light Plus near infrared light typically at a distance of about a foot to 2 feet from the light source depending on the intensity of the light source although that doesn't seem to be so critical but one can't be across the room from the red light source nor should one get right up next to the red light source so that there's a lot of heat generated from the red light source that one can feel”

“I think they work great the question is to what extent is that Improvement objective and measurable and what extent is subjective that being said there's a lot of evidence that shows that red light therapy in improves vascular flow in the skin”

“And it has been shown that light panels that are emitting red light or near-infrared light or typically both can also improve skin appearance if done for about 10 to 15 minutes per day, maybe five days per week minimum over the course of a few months.”
