Can I use LED light therapy if I also apply benzoyl peroxide gel (2.5%) every night?

Hello, and thanks for your question. You absolutely can, and in fact your results will be enhanced especially if you use the blue light therapy, and the skin irritation and redness that you sometimes get with using BPO will also diminish. Best, Dr Rosy Sandhu

I think the combination is actually helpful--especially if you use the calming and anti inflammatory wavelengths (red and infrared) in addition to the bacteria killing blue light.  I am not aware of any studies on the subject so I can not say definitiveIy.  However,  have my teenage son on a 10% BPO and he comes to the office for LED light treatments when he can, with no issues.  In fact the combo works better than either modality alone.
Hope this is helpful!
