Nowhere is "You get what you pay for" more true than with cosmetics.
There's not much difference between high end and super high end. For instance, a $20 MUFE lippie won't be noticeably worse than a $35 Guerlain lippie. Below that price point, though, you will begin to notice why you are below that price point.
it actually depends on your skin. i tried a foundation from mac but it doesn't blend with my skin very well. i decided to try on foundation from tarte and benefit and it blends with my skin very well!! thats why we have testers at a makeuo shop! ☺️
It depends what products. I personally love using Make Up Forever foundation when I go out to a bar or something because the quality is amazing. Although I do use mascara I got from cvs. Really thinking about it, I guess I do use more expensive cosmetic brands. I guess some last a bit longer because of their quality! I use Bobbi Brown gel eyeliner and it's lasted over a year and i use it everyday!
