Or like this?
To get Angelina's lip, prime your lips with your concealer then lightly dab your pink lipstick over it, just enough to give a hint of colour.
Combo 2: Under-eye corrector. I first heard about this from Wayne Goss, one of my favourite Youtube gurus at the moment! I didn't actually believe it would work until I attempted it on myself and...it was magical. Step aside, Bobbi Brown.
I find waxy textures are best for both techniques; they stay put longer. A liquid concealer tends to settle into the crease of your lips and fill them in awkwardly. Also, I wouldn't necessarily use an undereye concealer for this -- find one that matches the skin on your face, it'll be more useful in the long run. A gloss (instead of a lipstick) might also leave your under-eye area a little stickier than you're used to and make your lower eye area crease or wrinkle. Also, try to stay away from anything with a frosty or shimmery finish, it won't mix or set as well.
My concealer picks: TheBalm Time Balm in Medium or Light/Medium, Mac StudioFinish Concealer in NC35, Cle de Peau in Ochre
My lip picks: Kate for Rimmel in 05 (this is the best combination for my brown-based dark circles, along with Cle de Peau Ochre), NARS Morocco for those who have bluer circles, or NYX Elektra for really gray circles.
Any other double-duty tricks you have for me? You know I can't help myself.
