Now, imagine a sheep in all its woolen finery going through a similar experience, except rather than having a few bath-free days, we're probably heading towards a bath-free year, and its oil-soaked coat hasn't been cut in that entire time. Finally, picture what it would look like if someone came and collected the greasy substance that had accumulated in the woolly locks, and put the resulting gunk into a jar.

Hint: It would look like this.

This is lanolin, the greasy stuff secreted by wool-bearing mammals to help shed water from their coats, squeezed from their harvested wool and bucketed for many uses, including shoe polish, barnacle repellents and rust-proof coatings.

Oh, and also you smear it on your face.

"But I'd Never Use Tha-"

Do you use shaving cream? Shampoo? Well then there's a good chance you've had this stuff on your face and around (or in) your mouth. And as for the ladies (and the more adventurous males out there) you've likely had much closer contact with lanolin than you'd care to think about. In fact, if you've ever used lipstick, lanolin is the stuff that makes it greasy and sticky.

Maybe she's born with it, maybe she's got sheep grease smeared over her lips.

There are over 100 lipsticks on the market that contain lanolin, including some sold by renowned brands Revlon and Estee Lauder. Neither of whom have, as far as we can remember, based their promotions on the sheepish contents of their lip-smacking miracle workers.

Is it bad for you? We're not saying that. We're just saying it's gross.

And while some people actually take squalene pills on purpose for its questionable healing properties, we're not talking about that.

The photo of a shark enhances the sharkiness of this product.

"But I'd Never Use Tha-"

If you're a girl and, like most of our readers, have been alive for more than two years, there's a good chance you've had shark liver juice on multiple parts of your body. There are some important benefits of squalene that hold a huge appeal to the cosmetics industry: It's easily absorbed into the skin without leaving a greasy residue; it combines well with other oils; and it is recognized as improving the appearance of skin. For this reason, it is the ideal ingredient for use in all sorts of products from lip balm to sunscreen. The most common use appears to be in facial moisturizer.

Sadly, this isn't how moisturizer is branded.

Many cosmetic companies have shied away from squalene derived from shark livers as it's not considered cool to hunt them anymore, and have instead turned to alternative sources such as olive oil or wheat germ oil (though industry giant Unilever just stopped using it a couple of years ago).

It kind of puts Jaws in a new light, when you realize the sunbathers on the beach were smearing the guts of the shark's buddies all over their skin.

Now let's imagine that your ambergris has been building up for a while now, and it's time to get rid of it. Awesome. As a whale, you have two choices: poop it out, or throw it up.

It's coming out, either way.

Now here's the fun part: Somewhere a human is going to pick up your oily stomach excrement and shout for joy, because guess what? That s**t is worth stupid amounts of money. We're talking prices as high as $20 per gram. Ambergris has even been compared to a fine wine, as its quality increases the longer it has spent aging.

"But I'd Never Use Tha-"

People throughout history have used it as food flavoring, an aphrodisiac and incense, but these days you have it lurking in your bottles of perfume.

RUB IT ON YOUR NECK.

While it has a natural odor of its own, ambergris also enhances other fragrances by helping their scents to last longer. It is the perfumer's dream ingredient, as long as they neglect to list it as "whale s**t" on the back of their anti-stink bottles.

Recently, American companies have tended to shy away from the connotations of using this ingredient, whereas the French, as always, are more liberal in their views. Indeed, it is said that you can still find ambergris in the ladies' favorite Chanel No. 5.

Having a few million years on their hands, the tiny little organisms gathered together to bemoan their rough life at sea and dream of happiness in a luxurious fish tank. Over time, nature forced them together so tightly they formed a sedimentary rock known as diatomite, which is actually not the thing that we thought it was when we first heard the word.

The dead algae rock is recognized primarily for its abrasive nature; it is easily crumbled and the grains have a sharpness that is just perfect for slicing troublesome ants in two, or for cutting intestinal worms to death. That's about as badass as a rock made from dead slimy s**t can get.

"But I'd Never Use Tha-"

We'll just stop you right there, because the chances are if you've ever used an exfoliating body scrub, you've actually spent time rubbing dead fish tank algae all over yourself. Whilst DE is known to be damaging to some creatures, the grains are too small to do any cutting-based damage to humans, and are still rough enough to remove those pesky, dead skin cells that build up over time.

Interestingly, the Body Shop invites you to buy its Aloe Gentle Exfoliator, which it does it by promoting how its natural "...jojoba beads, which are round is in shape, glide smoothly against skin's surface to gently exfoliate even the most delicate skin." That's a filthy lie. You're not going to exfoliate s**t with round jojoba beads. You need the jagged edges of DE, which you can find sitting inconspicuously in its ingredients list and mentioned nowhere in its ads.

"But I'd Never Use Tha-"

Sorry to point this out, but yes. Yes, you would. While having nothing to do with pearls, this derivative of guanine does have a similar iridescence to oyster jewels, so it is frequently used in the cosmetics industry to add a certain luster to their products.

Like this.

So, if you've ever used a colored polish to brighten up the bitten stumps called nails found at the end of your fingers, the chances are you've spent time brushing dead fish scales over your hands, because natural pearl essence is a favored ingredient in a a s**t ton of nail polishes. Top brands who have CI 75170 listed in their ingredients include Bourjois and Maybelline.

Some companies have even managed to train fish to apply varnish directly!

You've already guessed that you or someone you love has smeared this on your face at some point.

"But I'd Never Use Tha-"

You see, cholesterol is found in another important place: your skin. And, more importantly, animal fat. It is one of the components in the uppermost layer of your skin where it helps to retain moisture while protecting the lower layers from exposure to the elements. Thanks to its skin conditioning and emollient properties, cholesterol is an ideal ingredient for helping the skin to retain moisture, which in turn helps to smooth out any wrinkles that have had the audacity to appear.

"Hurry, wipe this cheeseburger on your cheek!"

We can't help but notice that there isn't even a fancy sounding name to disguise the use of cholesterol in these anti-aging creams, including L'Oreal, Dove and Elizabeth Arden. We can only assume that this is because the anti-wrinkle cream branch of the industry is so confident of the need of the aging population to keep their youthful looks intact, they assume that there is simply no limit to what these people will rub into their faces. Considering they sell something called Snail Gel in the UK, they might not be wrong.
