October's Birchbox was pink in recognition of breast cancer.

I've become suspicious of pink things in recognition of breast cancer, since it's come out that often very little or no money goes to cancer research. Thankfully, this "awareness" does indeed come with a more tangible donation:
$104k to the Breast Cancer Research Foundation (BCRF) which will apparently fund a year's work in a lab. I presume that's for a single person and materials, not the whole lab, given what I know of the costs of breast cancer research from a friend who used to work in the field.
So maybe not earth-shattering, but at least it's tangible!

Let's talk about what's inside:

CLEAN White Woods
This perfume didn't trigger a migraine and smells vaguely like babies and not at all like woods. I actually like it despite myself, although it's not something I plan to buy as I cannot wear perfume at work or in much of my private life.
It still irks me that even when I tell birchbox I don't do perfume, the option is "no more than 6 times a year" which means half of my boxes contain perfume. But at least I can pass it on to someone who might like it.

Lollia by Margot Elena Shea Butter Handcreme
I love shea butter, and this is no exception -- it leaves my hands feeling super soft for ages. The name is "sugarared pastille" (a candy or throat lozenge) but I think it smells more like generic hand lotion to me. The scent isn't too heavy or noticeable, anyhow.

I do particularly like the retro packaging and little metal tube with the bees in the design. It's a little thing, but in the sea of hand cremes I've tried since I started birchbox, it's hard to stand out, and I think this one will just because it's got this classic pretty vibe going.
Of course, it also stands out in that it's got macadamia nut in it, which means it's an allergen for my boyfriend. It won't kill him if I use it, but he definitely shouldn't use it himself, and I can't really buy more once this sample runs out. Good thing Birchbox has basically removed any need for me to buy hand creme again anyhow. ;)

Acure Organics Cell Stimulating Facial Mask
Directions: Apply evenly over the face until you look like a green sea-monster.
Now these are the kind of directions I want to see on products I sample! ;) This comes out dark green, and you smell like a sea monster (with a hint of mint) as you put it on. I know you all want to know exactly what it looks like, so here's what I look like with half a tube of the sample on my face:

Sea monster indeed! Might also double for zombie makeup. Made me want to put on an episode of Arrow while I matched the green theme of the superhero.
It doesn't harden too much as it dries so I wasn't itching (literally or figuratively) to get it off. I was surprised to discover that when you attack it with a warm wet washcloth, it actually foams up. It doesn't *look* like it has permanently stained my washcloth either, although I suspect I should dump it in with tonight's laundry to be sure.
It left my face feeling clean and soft but perhaps a bit dry, so I followed up with a bit of moisturizer. I found it amusing and pleasant even with the seaweed-mint smell.
Incidentally, I think the whole stem cell and growth factor stuff is probably crap pseudoscience, because most things about makeup seem to be, but I haven't bothered to look up the details yet. If anyone knows, comments welcomed!

Number 4™ Texture Styling Crème
Why does this have a bunny on it? Is it cruelty-free, or specifically tested on bunnies? Do bunnies have styling cream secrets I need to know about? I do wish they'd said something about it on the sample.
I'm not a big user of styling creme on account of my default hair style being basically "long flowing hippie folk singer-songwriter" but I *had* wanted to try a waterfall braid and failed because after messing up a few times my hair had become so static-y that I couldn't get it to stay sectioned. So this arrived at the right time! I don't love the smell and it basically makes my hair feel a teensy bit slimy, but it *does* make styling easier, and I finally managed the motions to make the waterfall braid work.
I wish this product came in an unscented version, but it does do what it purports to do, and I'll probably make use of it again as I learn to perfect the waterfall braid!

Eyeko Black Magic Mascara
I was kind of disappointed to receive this, because it wasn't the sample that I'd chosen for this month's box! Thankfully, Birchbox customer support was apologetic and supposedly the correct sample is in the mail (I'll probably review it with some future box).
That said, this is a very nice mascara. Significant length, not too clumpy or thickening. It makes my eyelashes absurdly long without making them thicker or particularly heavier. Here's a photo (sorry about the weird angle, but it was the best way to show the lashes):

You can compare with the sea monster pic above if you're not sure what my lashes look like normally. But yeah, it works nicely, and I'm not sad to have gotten it after all!

Summary
This was one of the most consistently good boxes I've had in a while! I liked all the products. (Shockingly, even the perfume) My birchbox subscription keeps me stocked in all these product categories so I don't think I'll buy more when these samples run out, but I'll use all of these myself except for the perfume, and at least I know someone who will likely enjoy the perfume sample!
