Getting lash extensions can be an uncomfortable process, involving lying with tape under your eyes on a bed for two hours. Chief technology officer Nathan Harding co-founded Luum Lash when he realized it could be improved by using robots. Luum swaps sharp application instruments for soft-tipped plastic tools, uses a safety mechanism to detach instruments from the machine before they poke a client, and employs machine learning to apply lashes more efficiently and precisely. An appointment that usually takes two to three hours takes one and a half with Luum. Luum lash artists, primarily working from the Lash Lab in Oakland, Calif., can see “up to four times the clients” daily as they could operate without the robot, says CEO Jo Lawson. So far, Luum has applied more than 160,000 eyelash extensions, charging $170 for a full set. Luum has secured 51 patents in 25 countries and plans to launch at Nordstrom’s Westfield Valley Fair Store in California in November.

NuFace’s facial toning devices have been gaining popularity in recent years, but the latest model, the Trinity+ Complete, offers the combination of microcurrent and red light therapy, a hugely popular and study-backed skincare treatment. The handheld facial device has three magnetized attachments that promise to tighten facial muscles and smooth wrinkles. “As we get older, we need to exercise more to keep our bodies toned and tight,” says NuFace co-founder and CEO Tera Peterson. “The same concept goes for delicate facial muscles.” Thirty-six concentrated red LED lights are designed to smooth skin, while two attachments for administering microcurrents (one for targeting around the eyes) use up to 425 microamps to increase cellular adenosine triphosphate, providing a nearly instant, at-home facelift. The device prioritizes safety by shutting off after 20 minutes.

“If you cut yourself, what’s the first responder?” says Rion Aesthetics CEO Alisa Lask. “Platelets—your blood.” Going off that premise, creators of Rion’s Plated Intense Serum purchase platelets from a blood bank to harness the type of exosome—an inter-cellular messenger—responsible for signaling cell renewal. With billions of exosomes per two-pump dose, Plated uses its Renewosome technology to decrease facial redness and maintain shelf stability of the serum—a challenge for stem cell-containing products. The company has the medical credentials: Rion was founded by Mayo Clinic physicians at the Van Cleve Cardiac Regenerative Medicine Program, where they discovered that exosomes play a key role in healing. The company now produces platelet-derived exosome products currently in clinical trials for wound healing, cardiology, and orthopedics, while Lask’s spinoff focuses on aesthetic applications. A 2023 clinical study found that “all patients experienced improvement in redness, skin irritation, skin tone, texture, and smoothness” with nine weeks of Plated use.

This year, for the first time, TIME will debut a ranking of the World’s Top GreenTech Companies, in partnership with Statista, a leading international provider of market and consumer data and rankings, alongside its second annual ranking of America’s Top GreenTech Companies. These lists will recognize the most innovative, impactful, and successful companies whose aim is to reduce human impact on the environment.

Because many companies in this space are young, TIME and Statista are accepting applications as part of the research phase. An application guarantees consideration for the lists, but does not guarantee a spot on either list, nor are the final lists limited to applicants.
