 making you less tired throughout the day and less lethargic. Maybe you are, like I said before, dealing with acne. You want that green light, that yellow light, that blue light. That's what's going to help it. So, yeah, it's kind of based on you want to do your own due diligence with it. I can't prescribe it over the phone for who needs what, but picking what you think you need and what's available to you is going to be your best options.
