How to put on concealer/foundation/bronzer 'perfectly'?

Concealer and foundation both come in powder, liquid, and matte forms. The difference is that concealer is usually more strongly pigmented and is used for just spot touch-ups (say, if you have a pimple or something that you want to hide). Foundation is used all over the face to even out your skin tone. The most important thing about picking a concealer and foundation is to make sure you get the right shade. DO NOT get a shade that is not right for your skin tone. Then you'd end up looking like an oompa loompa, and that's not attractive. My second tip is don't cake on your make up. When it comes to foundation, a little bit will go a long way. Since you're young, I would personally recommend using a powder foundation. It's lighter, and it's great when you're still learning to do your make-up since it won't cake as easily. Apply with a good quality make-up brush. Try to avoid using your fingers TOO much, as it can make your skin oily (you can use them a little for smaller spots, but not a whole lot). Also make sure you apply your foundation to your eyelids as well. Most people's lids are actually lighter than the rest of their face because the skin is so thin, so just doing this should make a TON of difference. As far as the pictures you provided, I would go with a look like Miley's. It's nice while still looking natural. Stay away from colors that are too bright. It can make you look SUUUUUPER old. Never a good option. Also, don't wear make-up every day. If you're just bumming around the house or something, give your face a day to breathe. Also always take your make-up off before you go to bed. Sleeping with make-up on can age your face up to 7 days for every night you leave it on (not a big deal if it happens a few times, but that adds up!). Anyway, hope this helps!
