How do I get the minerals out of the brush?
Each loose mineral makeup brush arrives to you in an aluminum tin and inside the tin are explicit instructions on how to prime the brush.
Directions: Remove the protective cap and pull back the protective brush covering. Make a fist with your left hand and with the brush in your right hand press the bristles onto the middle knuckle so the bristles fan out (like a hoola skirt). Apply in small circular motions until pigment releases (in about 10-15 circles). Brush released pigment into the brush. The brush is now primed and ready to apply to the face. NOTE: You do not have to repeat this process every single time. Although you will not see a lot of pigment released with each use, the brush is designed to release the right amount of product to give a natural look.

How do I prevent my brush from clogging?
Keeping the brush clean is the best way to prevent it from clogging. To clean the brush, use the Colorescience aromatherapy cleanser, which is free from chemicals. Spray a small amount onto a paper towel and hold the brush in an upright position (bristles facing the ceiling) and wipe the brush back and forth on the paper towel. DO NOT POSITION THE BRUSH IN AN UPSIDE DOWN POSITION, WHICH IS BRISTLES FACING TOWARDS THE FLOOR AS THIS WILL CAUSE THE POWDER TO MIX WITH THE MOISTURE IN THE BRUSH CLEANER AND BECOME CLOGGED.
The second thing to remember is that the brush cannot be applied to a damp or wet face. Moisturizer must be completely absorbed and perspiration must be wiped off the face before applying loose minerals.

How long will loose minerals last?
The best thing about Colorescience mineral makeup is that once applied, it will last for a minimum of 8 hours, so you will not need to re-apply throughout the day, with the exception of the finishing powder, which is used to control and absorb oil.
General guidelines are as follows:

Mineral Primer (Line Tamer and Wild To Mild) Approx. 2 months
Loose Foundations : 6-9 months
Loose Blush: 9-12 months
Loose Bronzer: 6-9 months
Loose Finishing Powder: 3 months
Mineral Compact: 2 months
Sunforgettable Powder SPF 30: 1-3 months

What determines how much coverage I get with the mineral makeup?
It depends on a couple of factors. First, the type of product you select and secondly, how you apply that product. If you want a natural, sheer to medium coverage, go with the loose powder in the brush. If you want a medium to full coverage, the compact will be your best option. Many clients have both because there are times when you want fuller coverage, such as a special event, or when being photographed. Because the compact offers the greatest coverage per square inch, it is best to apply sparingly with a brush until you get the hang of how much to apply. If you do apply the compact with the sponge, apply to the outer portion of the face and work in (as opposed to applying in the T-Zone and working outward. This will prevent too much product being applied to the face.
