I like this mascara quite a bit. I initially bought it in 2009 but lost it & thought that some "cult favorite" mascaras would be better (i.e. Maybelline Falsies, L'Oreal Voluminous). Again, mascara is just extremely YMMV that you just have to try several different ones to see what works for you. I am confident that this will be a staple in my mascara stash, though.
I have typical Asian lashes. They're thin and grow downwards, but I am thankful that I have a *bit* of length to work with. Throughout the years I have used mascara, I am a firm believer that the brush is a key player to how the end results look (although the formula is pretty important too!) For me, straight wands keep my lashes more organized than curved wands. Traditional bristles work better for me than do plastic/silicone bristles, but I'm not sure why. Now, I've heard a lot of times that bigger brushes are better for volume. I find this to be true, but I also run the risk of leaving a smudgy mess on my eyelids. This is where this mascara surprises me. The wands are thinner than your typical volumizing mascara. I was amazed by the amount of volume that I got, considering the size of the brushes.
If you do get this mascara, play around with it to see what works for you. I've read several reviews saying to apply the "2" side first, but I'll share what works for me. Before I get into that, I should say that I don't think that this is a primer+mascara duo. If anything, it's more like a mascara+topcoat duo. Side "1" is the actual mascara. I usually layer 2-3 coats of this side. Side "2" is the water-resistant topcoat that also adds a small, extra boost of volume. I add 1-2 coats before Side "1" dries up, wait for all of it to dry, then curl my lashes. The end result I get is dark, full, and clean lashes that stay curled all day. I *do* wish that this gave a bit more length, but it excels at other qualities that I look for in a mascara.
