Light therapy treatments can help reduce inflammation and increase blood flow to damaged tissues. To treat specific problem areas, it may be beneficial to use light therapy multiple times per day, until symptoms improve. For general inflammation and pain management across the body, use light therapy at least 5 times per week.
Conclusion: Consistent, Daily Light Therapy is Optimal
There are many different light therapy products and reasons to use light therapy. But in general, the key to seeing results is to use light therapy as consistently as possible. Ideally every day, or 2-3 times per day for specific problem spots like cold sores or other skin conditions.
