I like to use natural brushes for my eyes and cheeks. Basically, anything that is a dry makeup. Some good bristles that you'll find in makeup brushes are pony hair, goat hair, sable, and italian badger. These are really soft, and usually made very well. This way you'll get a good application without your eye shadow falling everywhere. I use crown brushes. They have a fabulous selection of brushes and they are VERY inexpensive!! The quality is great. Lots of pro's use these and you won't believe what a good deal they are. When it comes to designer brushes such as MAC, you're really only paying for the name.
Now, there is a time for synthetic brushes. Taklon brushes are synthetic and good for using cream or liquid makeup. These bristles are soft yet firm and don't absorb product like fluffier brushes do. It's also a lot easier to clean your lip glosses and concealer off of these brushes.
The good news is that you don't need a billion different brushes to achieve the look that you're wanting to get. I don't ever use a foundation brush. It's so hard to use and all it does is smear your makeup around. If I'm doing makeup on someone else I use a sponge. If I'm putting it on myself I just use my hands. You'll get the blest blending that way. You can always be creative and use one brush for multiple things. Here are a few basic brushes that I like. These are brushes you need in your makeup collection!
|large fluffy brush for blending eye shadows together|
|this flat brush is for lining the eyes after applying eyeliner. You can also just use it with eye liner to blend it in to your lid so you don't have a super obvious line|
|basic eye shadow brush for the eye lid area|
|this is a contouring brush that goes directly into the eye socket. Set your brush there, and rub the color in back and forth until it's blended in well|
|this is a lip brush, but you can also use it for a concealer|
These aren't all crown brushes, I just tried to find photos of brushes that have the same shape of what you're needing. Hope this is helpful to y'all!
