The physical interaction between two or more systems, also known as coupling, can give rise to unique and unexpected effects.

Finally, there’s a risk that red light therapy may not work for you. “The amount of weight loss is modest at best,” Dr. Ali ...

The point is that we generally consider light to be good, safe, even comforting. Yet when it comes to our skin, things are a bit more (maybe a lot more) complicated. It’s well established that many of ...
