L’Oreal Forgoes Animal Testing by 3D-Printing Human Skin

To save animals (and money), the cosmetic company turns to bio-manufactured skin samples.

Organovo Skin

Ever since testing on animals fell out of fashion, cosmetic companies have struggled to discover ethical ways to test new products. Recently, L’Oreal partnered with Organovo, a bioprinting specialist, and announced a solution to the dilemma: they would start 3D printing their own human skin.

How to Make Your Own Beauty Products from Scratch

Here are some simple recipes for DIY beauty. Best of all? You already have all the ingredients in your kitchen.

Let's keep things simple this week. When it comes to personal-care products, we are big believers in streamlining what you use—see "Eight Products You Think You Need But Don't" for a refresher—buying less in general, and getting creative. We have both always loved experimenting in our kitchens and our bathrooms, checking ingredients in products we love, isolating the main ones, and then trying them on their own. Sometimes it works: A favorite hair leave-in contained aloe, for example, so one day we tried aloe alone and found that, lo and behold, it worked just fine on its own. And sometimes it didn't. Over the years we have tried dozens of DIY beauty recipes to find ones we like—and that work. Below are our favorite six. And the best thing about these is that none contains more than four ingredients, and chances are good you have them all in your kitchen already. So get cookin' and if you have your own, be sure to share it in the comments.

Label, Rinse, Repeat: A Guerilla Labeling Campaign Takes on Baby Shampoo Carcinogens

Public health activists take carcinogen labeling into their own hands.

Johnson & Johnson's baby shampoo is a comforting relic of our youth. But "No More Tears" becomes a bit sinister with the realization that it contains two preservatives—1,4-dioxane and quaternium-15—that release carcinogenic formaldehyde. Parents asked the company to remove the toxins two years ago, but recent testing by the Campaign for Safe Cosmetics showed that small amounts are still present in the formula used in the United States. (Foreign countries with better regulation already force the company to put out carcinogen-free products.)

This awesome illustration shows us how amazingly (and disconcertingly) inescapable cow-derived products are, and comes to the hilarious conclusion that there is no such thing as a vegan.

If you're a vegan, do you go to pains to avoid the things listed here? Did you even know about most of this?

Yesterday was a good day for bunnies: Scientific American reported that researchers now have a new way of testing toxicity that doesn't involve adorable, helpless (and scientifically useful) animals. Instead, it involves lab-grown human skin.

It sounds like something out of science fiction—but at the same time it seems kind of weird that it hasn't been done yet, mainly because it has the potential to be very, very useful. We come into contact all day with things—from personal care products to household cleaners—and we don't know nearly enough as we need to about their safety. One of the big problems with toxicological testing has always been the fact that there's no ethical way to test chemicals on human subjects—and so scientists have relied on animal data.

If you're the sensitive type—the always sneezing, quick-to-get-a-rash-from-a-new-detergent guy or gal—someone has probably already told you to avoid fragrance. Ditto if you've ever been pregnant. In fact, it’s come up as a major no-no in every post we’ve done in this series. But how much do you really know about fragrance? Chances are, not a whole lot. Like most things in the self-regulated personal care business, it's shrouded in mystery—but this is an especially thick and stinky smokescreen.
