I don't know whether it is the management company or the paid endorsements or the youtubing, but I think CH's blog has become just another mouthpiece for promoting stuff.
I think evidence has never been CH's strong point. I think she is genuinely funny and has a warm and humorous style, but I am not super convinced by her advice. She often tells people to do certain things 'because I told you so'. I am not sure she always understands why or how stuff works. Other skincare bloggers do their homework better, I personally prefer bloggers who back up their claims up with evidence. Beauty Brains, Pocket Derm, Skin & Tonics, Fifty Shades of Snail, even Paula... They all have helped me to understand skincare and its active ingredients. And many test a product for much longer before reviewing it - when I buy a jar of something, I use it for months so I am really interested in the long term view... Kundry here on S&B does a far superior job describing what works and how and how to make the most of your budget!
Personally, I think the brand endorsements are undermining CH's credibility a bit. She has this fundamental mismatch that many of her followers are into budget stuff and would be happy to shop at supermarkets and Boots, but the higher end products have bigger PR budgets so she has to be their spokesperson. All that Zelens stuff just bores me to death, sorry, and the Cult Beauty box was also priced totally beyond what most of people here would be ready to pay.
