The Product & Individual Results
Best used for: Application of liquid foundation
Over-all Rating: 5/5
This brush applies foundation like a dream. Believe the hype - I am now a believer! I have been reaching for this brush since the first day I tried it! I've seen minor shedding on this brush (a few hairs on the first few uses) but it's still densely packed.
Best used for: Eye shadow blending
Over-all Rating: 3 / 5
Perfect size for blending darker shadows in the corner of the eye. I found this brushes a little stiff when you first use it which doesn't allow the color to blend out. This was my least favorite brush.
Best used for: Eye shadow blending
Over-all Rating: 4.5 / 5
The size may look to large at first glance, but this is the brush to use to diffuse the eye shadow. If you make a mistake and apply too much color - use this brush to blend out the color. You can not over blend using this brush! Go to town and blend using a 'windshield wiper' motion. This is now an every day brush for me. I noticed minor shedding on the first few uses.
Best used for: packing on shadow/pigments or applying highlighter under the brow
Over-all Rating: 4 / 5
The tightly packed bristle let you pack on the color using this brush. This brush allows you to pricely place the shadown where you want it, and the densely packed bristles minimize fall-out. I have not experienced any shedding using this brush.
Best used for: applying shadow under the eye (great alternative to using eyeliner) or using it to apply shadow at the corner of the eyes to create a smoky look
Over-all Rating: 4 / 5
The bristles on this brush are very soft, and apply the color precisely where you want it. and helps avoid fall-out. I have not experienced any shedding.
