Personally, I have taken few things from his routine and double-checked it with other sources and more importantly found much cheaper products/things locally than the ones that are advertised (even though, most of them are fine anyways such as in Skincare he uses standard Cerave stuff).

Do note that this is -one- guy trying basically everything that seems plausible. It would likely result in frequently switching up things that are not researched well.
