The fact that I'm even testing "line fillers" bums me out (but that's a blog for a different day). However, the fact that I actually found one that really seems to work cheers me up. So, it all balances out in the end.

I'd been reading about products that purported to temporarily "fill" facial lines and because I, a) have some that need filling and, b) don't have the bankroll, nor wherewithal, to get syringes stuck into my face every two weeks, I decided to give a few a whirl.

I applied each onto my entire face as a makeup primer and judged them on how they felt and how well they camouflaged those darn crevices.

Here's what I tried...and what I think:

Product No. 1: Redpoint Age Minimizer Line Filler, $19

Thoughts: This felt very lightweight on my face (probably because, unlike most, it doesn't contain silicone) and went on smoothly and, in turn, made my eye makeup go on like a dream and kept it from gathering into the lines on my eyelids. It did not seem to "fill" in any lines, but did make my face feel soft.

Overall rating: 4 of 10 stars

Product No. 2: Renee Rouleau Instant Line Filler, $62.50

Thoughts: Like its injectible cousin, this product contains hyaluronic acid, here, in the form of "filling spheres." These clever little spheres bond together to fill out and "plump" up lines and, let me tell you, it really works. Of course, it only lasts till you wash your face, but while it's on it's pretty cool. Plus, it felt good, not gloppy, going on and it does have vitamin C in it, which is supposed to be good for anti-aging.

Overall rating: 7 of 10 stars

Product No. 3: MAC Prep + Prime Line Filler, $19.50

Thoughts: Despite the fact that this felt a little tacky when I was applying it, once on, it was smooth, matte and really seemed to magically conceal most of my lines -- especially the finer ones. Plus, it contains some ingredients ("Gatuline Expression" and Argireline) that are purported to boost skin's collagen production. We'll see.

Overall rating: 8 of 10 stars

So, yes, MAC was the winner for me (surprising, since I've been eschewing their stores since I hit 35) and, while I'm not blown away by how well it works, it does a good enough job and keeps my hopes bolstered that the next big thing is right around the corner.
