Pencils Prismacolor

If you've used eyebrow pencils before you understand just how incredibly handy they are for drawing on incredibly realistic eyebrows.  You can even use the Paint Eraser to make minor adjustments to eyebrows that you aren't completely pleased with.
Making Pencil Drawn Eyebrows Permanent.
You need to heat set the eyebrows at 265 degrees Fahrenheit or 130 degrees Celsius for 8 minutes.  
Then apply 3D Texture Medium for a realistic feel and Matte Sealer to protect them:
Genesi heat set Matte Sealer
Genensis thick  Medium
In order to protect pencil drawn eyebrows you will want to apply a coat of Matte Sealer and for even more realism, use the 3D Texture Medium on each eyebrow hair for incredibly lifelike eyebrows.  Eyebrows that are not heat set properly and sealed may wear off over time, by heat setting them and then coating them with Matte Sealer they should last a lifetime.
Avaialable in different colors by choosing from the drop down menu.
