It's been quite difficult to compile, but here is my list for 2010.
Aromatherapy Soothing Temple Balm by deserving Thyme - delightful, relaxing lavender and mint scent. Love this little balm.
Fancl cleansing oil still seems to work well for me. I'm still searching for good, reasonably priced facial waters (softeners) and moisturizers. Nothing seems to leave much of an impression on me. At this rate, I might go back to DHC Acerola Lotion and Q10 cream, but I wish the formulas had nicer scents! Ah well, I'm picky like that.
Old standby Inoui ID eyebrow pencil has not been supplanted yet (not that I've been looking): I still have one refill left, so this will probably last me through 2011 with no problems.
Kate Supersharp Liner was again my favorite liquid liner of the year. Reliable; I've been using the black brown version for more than a year and it still hasn't dried up! I'm rather impatient to start using my backup at this point.
SilkyGirl Funky Eyelights Eyeliner pencil: colorful and inexpensive, and I can set it with eyeshadow.
Canmake cream blush: the packaging is functional, the product is easy to use, and it's cheap. I can't comment on the lasting power as I haven't noticed, but it's useful for me!
MAC beauty powder: it doesn't show up at all if I swatch it on my hand, but on my cheeks it's wonderfully subtle yet contours and adds a sheer wash of color to my cheeks. Wonderfully easy to use! And huge; I wonder if I'll ever use it up.
美禅 Be-zen x Chigira Keiko lip treatment: a sparkly glossy treatment scented with lavender, it's soothing to wear. Cosme.com reviews point out that it doesn't last that long, and it's not that moisturizing, which I would have to agree with.
Dior addict lip polish: a light comfortable gloss that's easy to wear.
I stuck to old favorite Opera MyLash mascara. I plan to do more experimentation next year, as there are a lot of reasonably priced mascaras getting good reviews from bloggers.
I've been using bb creams on an almost daily basis, but mostly as tinted moisturizers as I don't skip any of my skin care steps, and have not found them particularly bad or good. I just have a lot of them and I'm trying to use them up.
Vera Wang Anniversary was a surprisingly easy-to-wear perfume. Drawn in by the promise of gardenia, I find the bottle gorgeous, the perfume pleasant, but in the end, not terribly memorable. Still, I will happily use this up, as I don't get sick of it.
YSL Golden Gloss is such a pretty, pretty gloss and very wearable. I love the scent too, but texture-wise it's a bit too sticky for my taste. As such, I probably won't repurchase, if I ever happen to finish this gloss.
