Apply a layer of our PureLash Extender and Conditioner first. You'll be amazed how it thickens your lashes. It also means that you'll use less mascara. Allow to dry until tacky and then apply your favorite formula of mascara. Be sure to rock the mascara wand at the base of your lashes first. This is where you want the most product, If you are going to layer mascara, don't wait for each application to dry. This is what makes lashes stick together. Don't pump brushes. This will force air into the tube and help to dry out the product. Simply twist the brush in the tube to pick up more product. Brown or grey can look softer around the eyes than black. Too much mascara can be aging.

Comments about Jane Iredale Longest Lash Thickening and Lengthening Mascara, Slate Grey, .42 oz:

Great color for those with light eyes / skin and who do NOT want black mascara to "close" in on their eyes! It's a bit expensive, but it looks so good with the whole light / pastel look that us pale blondes look so darn good wearing! It defines and separates -- doesn't really volumize or lengthen -- and sometimes it can be clumpy -- but given that there are virtually no other light gray mascaras out there AND it IS very conditioning -- I love it!
