Some of these were introduced this year, and some were new to me. All of these became favorites of mine.
In no particular order:
Maybelline Instant Age Rewind Dark Circle Eraser -- This has a nice lightweight formula that doesn't settle into the lines around my eyes. It covers decently, and I think it is quite fun to use because of the little puff applicator.
Maybelline Color Elixir lipgloss (review) -- I think these have a lovely formula. They were introduced late in the year, but they quickly became a favorite of the year. They are some of the nicest lipglosses on the market, in my opinion. They feel plush and hydrating on the lips.
Neutrogena MoistureSmooth Color Sticks (review) -- These smell wonderful (if you like fruity scents), are very hydrating, and make the lips feel softer, even after they wear off.
Too Faced Sweethearts Perfect Flush Blush in Candy Glow-- I like that this has 3 colors of blush that you can either swirl together, or use just the coral color or the pink color (although you need a smaller brush to pick up just one color or the other). I do consider this a highlighting blush due to the shimmer, but it doesn't look glittery on the skin.
Josie Maran Coconut Water Cheek Gelee in Poppy Paradise (swatch) -- This blush is great for giving a natural flush to the cheeks. It's very easy to apply (I always use my fingers for this one) and feels sort of cooling, which is especially nice in the summer.
Too Faced Pretty Rebel Palette -- I didn't get this palette until November, but it is one of the best palettes I own. The shadows are very pigmented and soft, and there is an excellent mix of neutrals, brights, metallics, and darks.
Fyrinnae Pixie Epoxy -- This was one of the great discoveries of the year for me. It is amazing how different shimmery and glittery shadows and pigments look over this.
Benefit They're Real Mascara -- I really only wear this when I want dramatic lashes. It separates, volumizes, and lengthens all at once. It is more difficult to remove than most non-waterproof mascaras which is why I don't wear it everyday.
JinSoon Nail Laquer in Nostalgia (review) -- This is my favorite nude nail color. The formula is long-wearing and shiny, even without a top coat.
Sally Hansen Lustre Shine Nail Color in Firefly (swatches)-- I wore this almost non-stop in the fall. It's a complex color that changes from pinky copper to gold with some green depending on how the light hits it.
Obviously, this is not a complete list of favorites (that could get very long), but just a few that stood out to me.
