Dani Sprague's Reviews > Skincare Decoded: The Practical Guide to Beautiful Skin

Quite informative, and very useful. My critiques are that it needed another pass in editing (e.g. there were some grammatically broken sentences) and that the authors used some logical fallacies. I remember a line going something like "the $500 serum isn't going to be 10x better than the $50 serum", which is absolutely true. There are diminishing returns, but might it be twice as good? Some would still pay for that.

Regardless, I still highly recommend.
