Mineral is better for your skin and won't clog your pores, but if you have oily skin, it really accentuates the shine. If I put mineral makeup on in the morning my face looks super shiny and kinda gross in only 2 hours. Liquid makeup doesn't do that for me...I can go a whole day and my face still looks pretty well covered and has a matte look.
So in other words, I can expect mineral makeup to "disappear" in just a few hours' time. (Yes, I have very oily skin; it's even worse if I eat certain foods containing unhealthy oil(s), like mayo, for instance.)
If I wear liquid makeup beyond 8 hours, it begins to look worn, as my skin's oil starts breaking it down. But maybe that's due to me not yet finding the best liquid foundation for my skin. Hmm...
But, for covering up flaws, I would say mineral and liquid are equal. I really like the feel of mineral on my skin, and it does a nice job covering up scars and red areas.
I love the idea of having weightless coverage; yet the idea of spending money on something that I can only wear for just a few hours without it wearing off completely isn't so hot. Egads.
I'm guessing that reapplication isn't a good idea, in that you'd be getting the skin's oils/bacteria all over the application brush.
...Liquid makeup does the same! It just clogs my pores more, which isn't cool!
So do you wear liquid foundation every day--and for 8+ hours per day? And do you mean that it makes you break out, or does it cause clogged pores/blackheads?
If you have oily skin, go with liquid makeup and a good matte powder. If you have dry skin, go with the mineral makeup. I use liquid foundation (Almay 16 hr.) and a matte powder (MaryKay) and I love them both.
I'm still torn. I hate the feeling of a face-full of liquid foundation--which feels even more obvious as my skin's oil adds to the weight of it throughout the day; so adding powder on top of liquid foundation wouldn't work well for me. It's either loose mineral powder or a lightweight, oil-free liquid makeup. At least I can decide on that much.
