The first one is Light-emitting Diodes in Dermatology: A Systematic Review of Randomized Controlled Trials. That one includes review of a very large number of studies, came out just a few years ago in 2018, and I think is very clearly and cleanly laid out for anyone to access. And you can see the degree of effects of red light, for instance, on treatment of acne or scarring, et cetera.
