You guys do not know how much of a help you've been. I have a graveyard of products that I've just about gotten rid of. I'm often away for work so I have to order online, and rely HEAVILY on youtube gurus, but mannnn that strategyhas made me waste money. Now I know I need to look out for:
(1) those who adjust camera settings or wear shades that don't match their skintone, so they look darker or lighter or a different undertone than they are (you rely on the fact that they look your colour or wear the same shade and end up with another tombstone in the product graveyard);
(2) those who review a colour and say "it's what I'm wearing now" without showing the actual application. When it looks hella different on you, you check another video and realise they layered it with 10 million other products.
I've been burned, but never again!!!
