Dr. Amy Killen explains how red and near-infrared light stimulates mitochondria to boost ATP production, improving skin barrier function and reducing fine wrinkles in 20-30 minute sessions. Red light works best after procedures like microneedling or laser treatment to accelerate healing, but shouldn't replace other skincare.
There's a lot of studies on red light for skin, and the way that it works in the body in general is the red light and the near-infrared light, which is looking at about 600 to 1100 nanometer wavelengths, is really great for your mitochondria. Essentially signals your mitochondria, those power plants in your cells, to make ATP, and that is, you know, energy for the cells. And so we know that from skin research, applying the red light, you know, consecutively, usually it's 20 to 30 minutes at a time, can improve things like skin barrier function and hydration and, you know, small wrinkles and things like that. But there's more even research in the skin literature about about using red light after for healing purposes. So like after laser therapy or after microneedling therapy. In one of my clinics, we do a lot of regenerative facial injections with stem cells and exosomes. And I use red light therapy, you know, afterwards for those patients and have them use it at home as well to help hasten healing and increase stem cell recruitment in those areas. So I think it's a great tool. I don't think it is the only tool. Certainly you have to kind of stack tools in the skin to, to make them all work together. But red lights are one of my favorites.
