I am on spironolactone for my acne, so I am clear in that regard. I still have red marks left from the acne and rosacea inflammation, and this is why I am using Red/Blue light therapy. I am pretty pleased with the results - no, my skin isn't flawless, but I can't expect it to be after the horrors it's been through.
My red marks have been reduced as well as the small papules I sometimes get when my face gets too hot. My overall facial pinkness has been reduced as well.
Overall, I think that Clearwave is as effective as other Red/Blue light therapy products, but if you can find something cheaper or more to your liking (for instance, a product that it more convenient to use), you should go for that instead.
Also, making your own LED light board might be less expensive than buying one. Directions can probably be found through a quick google search. Good luck!
