3D printing skin!



L’Oreal to start 3D printing skin

French cosmetics firm L’Oreal is teaming up with bio-engineering start-up Organovo to 3D-print human skin.

It said the printed skin would be used in product tests.

Organovo has already made headlines with claims that it can 3D-print a human liver but this is its first tie-up with the cosmetics industry.

Experts said the science might be legitimate but questioned why a beauty firm would want to print skin.

L’Oreal currently grows skin samples from tissues donated by plastic surgery patients. It produces more than 100,000, 0.5 sq cm skin samples per year and grows nine varieties across all ages and ethnicities.

Its statement explaining the advantage of printing skin, offered little detail: “Our partnership will not only bring about new advanced in vitro methods for evaluating product safety and performance, but the potential for where this new field of technology and research can take us is boundless.”

It also gave no timeframe for when printed samples would be available, saying it was in “early stage research”.

Experts were divided about the plans.

“I think the science behind it – using 3D printing methods with human cells – sounds plausible,” said Adam Friedmann, a consultant dermatologist at the Harley Street dermatology clinic.

“I can understand why you would do it for severe burns or trauma but I have no idea what the cosmetic industry will do with it,” he added.

3D-printed livers

The Wake Forest Institute for Regenerative Medicine has pioneered the field of laboratory-grown and printed organs.

It prints human cells in hydrogel-based scaffolds. The lab-engineered organs are placed on a 2in (5cm) chip and linked together with a blood substitute which keeps the cells alive.

Organovo uses a slightly different method, which allows for the direct assembly of 3D tissues without the need for a scaffold.

It is one of the first companies to offer commercially available 3D-printed human organs.

Last year, it announced that its 3D-printed liver tissue was commercially available, although some experts were cautious about what it had achieved.

“It was unclear how liver-like the liver structures were,” said Alan Faulkner-Jones, a bioengineering research scientist at Heriot Watt university.

Printing skin could be a different proposition, he thinks.

“Skin is quite easy to print because it is a layered structure,” he told the BBC.

“The advantages for the cosmetics industry would be that it doesn’t have to test products on animals and will get a better response from human skin.”

But printed skin has more value in a medical scenario, he thinks.

“It would be a great thing to have stores of spare skins for burn victims.”




3D printed makeup!

Want any shade or colour of eye shadow, lip gloss, nail polish or lipstick? 3D printing will one day allow you to order makeup customised specifically for you! 🙂


For many people of varying skin tones, finding the perfect shade of makeup is a near-impossible task. That’s why Grace Choi wants to give people the tools to create a customized line of makeup at home, using 3D printing technology.

Choi is the founder of Mink, a desktop 3D printer capable of creating any color of eye shadow, lipstick, lip gloss, and nail polish. Instead of using standard ink, Choi’s product uses FDA-compliant ingredients. Future iterations will be able to process foundations and face powder, too.

“Beauty is defined by the colors [big] companies choose to manufacture, which are the ones they think will sell and the ones we see on the models they select to represent their brands,” Choi said in an interview withForbes. “What if you want a color that you think is beautiful but the industry doesn’t? You can’t have it because you can’t control what the industry produces, and the most tragic thing about it all is that we don’t even question it. We have been trained so well by these companies that we blindly accept the narrow band of options in front of us.”

Not only does Choi’s device make women less reliant on the makeup industry — which consulting and marketing research firm Lucintel estimates will balloon to $265 billion globally by 2017 — it could potentially solve the problem many women of color face. Most off-the-shelf makeup is made with Caucasian faces in mind. As Rebecca Pahle ofThe Mary Sue pointed out, letting women choose the specific shades they find appealing will help limit the power the makeup industry has in defining which tones are considered attractive. This is important. As The Daily Beast reported, most major cosmetic brands have never featured an Asian model, except for Estee Lauder, which worked with Liu Wen in 2010. Letting women create their own colors gives them the power to say what they think beauty looks like.

That’s not to mention that if Choi’s product succeeds, it will make her one of the few female faces in the booming 3-D printing industry, which made $3.1 billion last year, according to a report by Wohlers Associates.

Choi said during her TechCrunch Disrupt presentation in May, where she first presented Mink, that she was inspired to create the device after becoming frustrated with the meager selection of mass-produced colors at drug stores, and having to go to expensive high-end stores like Sephora to buy specific shades that suited her. She wanted to give the power of selection to women instead of high-end corporations.

So how does it work? You simply snap a picture or take a screenshot of the hue you want and figure out its hex code by using a color picker. Then, using a photo-editing program, you enter the hex code in a new document, which will create a square of whatever color you want. Finally, you print the color out the same way you would print a document. However, instead of watching the printer spit out lines of text on a piece of paper, the 3D printer builds powder or cream in the shade you selected inside a special Mink container.

The device, which is expected to go to market later this year, will retail for around $300, while ink, substrates, and customized cases will be purchased separately. Considering that Mint.com reports that the average woman spends $15,000 on makeup during her lifetime, $300 seems like a bargain.
