Is infrared light good or bad for the skin?

Hi, I am trying to get an answer to a simple question although I understand the answer may not be as simple. I can't find any clear information on whether infrared light helps skin produce collagen or if it accelerates aging of the skin. I would be using it in combination with low level laser and Red LED. Any information will be helpful to me as I don't want to be making the wrong choice in trying to preserve the integrity of my skin! Thank you.
