@Jordan2 I get it. I watch the makeup artists from time to time (and the dermatologists to see what's new and exciting.
The makeup YOUTUBERS can receive products without asking for them. The companies want their products seen especially by those who have a large audience. The Youtuber can make a "deal" to positively review them or some let the companies know they'd like to show the products, but don't want to be obligated to give a positive review or comments if they don't like them.
I receive some skincare and makeup that I have signed up for (sent an application to recieve promotional makeup), sent to me by other makeup artist friends or counter artists I've had a long relationship with at large department stores who would
like me to promote their line.
I'm not a YTber, but when I do a client's makeup and they enjoy a product, I can refer them to the website or store that sent it. I have no obligation to do that. I wait for the client to ask. It's a WIN/WIN for me. The client's happy and the makeup line sells her what she'd like to use on her own. I may receive more makeup from the company if that happens.
The makeup artists online like Tati and others have the opportunity to try the entire line of shades they are sent. They can either keep them, donate or put them in their kit to use on clients.
Let me know if you'd like some others to follow, but it can be addictive. Lol I find myself on there way too often.
