Foundation and Concealer makeup?

Hey I'm 16 and new to trying makeup, as in foundation and concealer. I have sorta acne prone skin, and I am using Nars Glow Foundation, and MAC Concealer. One question I have is that, is it bad for your skin to be using two different brands?
Also, I started using Nars Foundation over the summer, and realized I needed concealer..a week or so after I was using both, I realized I had gotten small, red dots on my cheeks. It's not really "acne" just bumps I guess? Not really sure how to descirbe. I'm not sure if my skin is getting used to makeup, or if it's clogging my skin, or just too much on? I also have dry skin.
Can any MAKEUP ARTIST out there help? Any tips or anything I'm doing wrong?
I'm not sure which is aggravating my skin- the foundation or the concealer? Have you heard any bad/good things about these brands?
thank you!
P.S. I use my foundation then concealer, is that right? Also put dabs on my hand, then use a brush for foundation, my (clean washed) finger to apply concealer.

Its fine to use two brands, but sometimes they dont match all the way, which can be noticeable. . The NARS provides little coverage. Why not try a full coverage foundation instead to no longer have to use concealer? Try Kat Von D Tattoo Lock It Foundation. Its full coverage. Or try BECCA Satin Finish Foundation. Its buildable coverage, so you can cover areas where concealer would have previously been needed.
