What brush is used to line shadow under your eyes?
I always see girls with shadow lined under their eyes, but what brush are they using? When I try to do it, it doesnt seem to work out.
I agree with prettyinpa.
A stiff angled liner brush will give you controlled results. I think it depends on how diffused you want it to look.
Something like this by Hourglass is what I use on a regular basis. I like to slightly dampen the brush, dab off the access water, then into the shadow. You can use it dry as well, but damp will give more intense color.
If your looking to layer color or diffuse the look then I would go for something like this Sephora pro brush that is a pencil brush.
I love to use this brush first with a deep burgundy or blue color, then use the technique above to create the sharper line in the lashline.
