Fear not; the efficacy of LED light therapy is just as well studied as its
safety, and it appears that the side effects are few and far between when the procedures are followed correctly.
Just like anything else, moderation appears to be key; too much LED light therapy can result in mild redness and irritation, much like overexposure to the sun. Keeping your therapy times at the recommended limits can help to reduce the risk of these issues.
Many doctors as always recommend that you not use LED light therapy if you’re currently on any sort of medication that increases your sensitivity to sunlight, including Accutane.
Home LED light therapy devices are indeed among the safest methods out there, due to their reduced output capacities; if anything, they’re much safer than clinical visits in many ways.
