As the name suggest, this has the lightest formula of any concealer I've ever tried! The applicator is really fun too because it's not "static," but bends into any section of your face you might need - not just under eye area, but around the nose too. For being so weightless, the coverage is actually really wonderful. I also love that with this concealer I don't have to add setting powder. I usually do just to be safe, but I've noticed that on days when I don't set it, there aren't any creases!
I used Erase Paste exclusively for about three years before I decided to venture to the three mentioned above, so that should tell you something right there!! the coverage is wonderful, but my one any only gripe throughout my use was that I always used my finger to apply. I only switched because I wanted a different application method, but if I was to go back, I'd use my concealer brush and apply that way!! It's blendable and really does a wonderful job at hiding those dark circles under your eyes!
Regardless of what concealer I'm using, the biggest game changer in application has been the Beauty Blender! This little tool has totally redefined how I do my under-eye are and it really gets into the nooks and crannies of everything I'm trying to blend!!
I'm also really interested in trying Maybelline Instant Age rewind - have you tried this one?
What's your favorite concealer?
