These L.A. musicians investigated a medical mystery. What they discovered launched a new skincare line
The love story of musicians Ann Marie Simpson-Einziger and Mike Einziger was fortified in a lab.
After meeting through a mutual colleague in 2010, the Santa Monica-based couple’s courtship began the following year, as they were collaborating with Oscar-winning composer Hans Zimmer on a series of film scores. Einziger is best known as the founding guitarist of California-based rock band Incubus. His wife is a renowned composer and violinist for artists including Jethro Tull, Ringo Starr, Dave Matthews Band and Stevie Nicks.
The couple had been seeing one another for only about a year when together they stumbled upon a medical mystery. It resulted in a thrilling scientific discovery, the founding of a biotech beauty company called Mother Science — and their own unique happily-ever-after.
“It was an unexpected journey,” said Simpson-Einziger.
“We were simply trying to answer a series of unanswered scientific questions,” her husband added.
It all began in 2012 when Simpson-Einziger developed a fungal infection while traveling abroad. A classically trained violinist by trade, she was performing with composer A.R. Rahman in India when she noticed lightened patches of skin on her back and under her bra line. They resembled “loosely drawn flower blooms, with rounded edges,” she said.
After consulting her dermatologist, Simpson-Einziger was diagnosed with a temporary fungal infection called Tinea versicolor, which can lighten or darken skin pigmentation as a result of humidity.
“It’s an imbalance of the microbiome,” Simpson-Einziger said. “The condition was harmless, it resolves on its own and [I was told] that the lightened patches of skin would all go back to normal. But I got so curious.”
“We learned pretty quickly that there were no real hypotheses about how this was happening.”

Armed with an undergraduate degree in biology from the University of Virginia, the former physics and chemistry teacher pored through science journals like Pigment International and Chembiochem to find articles that better explained the science behind her skin condition. She then began to wonder if whatever had caused it could also be used as a skincare aid that reduced dark spots.
She enlisted the help of her then-fiancé, Einziger, who also happened to have a background in science. He had recently completed the two-year Special Student program at Harvard University’s Graduate School of Arts and Sciences, where he studied cosmology and evolutionary biology. He still had access to the university’s considerable research databases, which meant he could help her look up articles on Tinea versicolor. Soon, he joined her obsession.
“There was tons of literature to research, but nothing coming at it from our perspective,” said Einziger. “We learned pretty quickly that there were no real hypotheses about how this was happening.”
Though they still couldn’t prove it, Simpson-Einziger’s theory that her skin condition could be of use in the beauty world kept them both up at night.
“I actually had a nightmare that somebody took her idea,” he said.
It was then, in 2015, that he called Dr. Jonathan Sackier, a family friend and biotech and medical entrepreneur, who co-invented robotic surgery.
“I taught his daughter violin lessons when I was a recent college graduate living in Virginia,” Simpson-Einziger said.
“We went to [him] fully prepared that we were going to get laughed out of the room,” Einziger added.
Sackier remembers the couple’s uncertainty during the phone call. “Ann-Marie was in the background, whispering, ‘He’s going to think we’re idiots,’” he said. “[Mike] asked if I could identify what it was about the fungal infection that was causing depigmentation and having identified it, could I synthesize or somehow isolate the chemical so that we could do something to impact pigmentation disorders.”
A surgeon by specialty, Sackier connected them with his colleague, Timothy Macdonald, a scientist and professor emeritus of chemistry and pharmacology at the University of Virginia.
“I have taken many projects to him over the years,” Sackier said. “I call him ‘Dr. No,’ because he always says, ‘No, that doesn’t make sense. No, that won’t work.’ When I told him this, he went, ‘Holy moly, that’s impressive.’”
Macdonald began advising the couple and helped connect them with a North Carolina-based research organization called PharmaDirections. The drug development company helped design a scientific program to explore various compounds that had caught the Einzigers’ attention while researching.
After countless studies, they discovered that a naturally occurring molecule that had co-evolved with the human microbiome, Malassezin (pronounced mal-uh-say-zin), could be beneficial for sun spots. While the molecule was identified and named in 2001, the Einzigers were the first to recognize that Malassezin could be valuable in the context of skincare.
“Malassezin is made from a yeast,” said New York-based dermatologist Dr. Amy Wechsler. “When someone has the yeast infection on their skin, the skin often bleaches temporarily.”
The couple filed an application to patent the discovery in 2016. (It was officially granted in 2018.) They then worked with a team of scientists including cosmetic chemist Susan Goldsberry and beauty innovation entrepreneur Tim McCraw to develop Malassezin into a topical serum after previously manufacturing it through a separate process called chemical synthesis.
They began testing to see if it could benefit melanocytes, the skin cells that produce melanin, the dark pigment in question. The couple used their personal savings to fund the initial research.
“I justified it as, ‘How much would I pay for an education where experts in the field teach me how to characterize a molecule and then commercialize it?’” Simpson-Einziger said. “That one-on-one education was worth what we put into investigating this molecule.”
They brought on beauty industry veteran Edna Coryell, McCraw’s daughter, as co-founder and CEO of Mother Science in August 2017 to oversee further research and development, which involved in vitro studies, 3D cell cultures, ex vivo skin testing and genetic analysis. Coryell had never brought a new ingredient to the market until Malassezin.
“It is very rare,” said Coryell. “Truly, as we were going through [the process], it was writing the playbook for this.’”
The Einzigers also collaborated with Dr. Pearl Grimes, director of the Vitiligo & Pigmentation Institute of Southern California, who specializes in vitiligo and pigmentation disorders.
“This is somebody who’s been looking at Tinea versicolor for decades,” Einziger said. “Her first reaction was, ‘How did you guys figure this out?’”
“I was 100% fascinated,” Grimes said of reviewing their initial in vitro studies. “The science [and] the concept was disruptive.”
Grimes assembled a clinical program, which led to proof-of-concept data that’s since been published in peer-reviewed journals including the American Academy of Dermatology and Journal of Drugs in Dermatology.
She went so far as to take a skin biopsy from her own elbow for lab testing. Using VISIA skin analysis technology, she found that the serum helped fade hyperpigmentation on the sample.
“That’s when I really knew that it worked,” Grimes said. “I used it in a stubborn area, and I could clearly see via photographic documentation that it was responding.”
“Having holes punched in my face was an ultimate act of belief in what we’ve made.”
— Ann Marie Simpson-Einziger, co-founder of Mother Science and violinist
Einziger also biopsied a patch on his arm for Grimes to analyze. “We felt responsible,” he said. “Mine was done before we even did the human clinical study.”
Simpson-Einziger joked that she too “put real skin in the game” after she said she had her face punch-biopsied — a procedure in which an instrument is used to remove a deeper skin sample — three times.
“Having holes punched in my face was an ultimate act of belief in what we’ve made,” Simpson-Einziger said.
Once the Einzigers confirmed that the data supported their initial hypothesis in a human clinical study, they moved forward with a business plan for what eventually became Mother Science. (It joins the couple’s two other co-founded businesses, including Mixhalo, a networking technology company for live events.)
Mother Science — named as a nod to French physicist and chemist Marie Curie — was born as a result of raising an initial round of approximately $3.2 million in seed funding from a small group of venture capitalists and angel investors, including Hawktail’s Michael Polansky and Drew Houston, the co-founder of Dropbox. After more than six years of research, Malassezin became the DNA of Mother Science, which officially launched in 2023 with its first product, Molecular Hero Serum ($89). The product is meant to reduce hyperpigmentation and brighten skin.
“It’s a powerful antioxidant,” Simpson-Einziger said. “When we started testing, we learned that Malassezin happens to offer superior protection against hydroxyl and peroxyl free radicals, which are [some of] the most damaging. We had this molecule that was going to do something marvelous in protecting the skin.”
A second product, Retinol Synergist ($96), was released earlier this year. And Molecular Genesis Barrier Repair Moisturizer ($68), featuring Malassezin, will be released on Jan. 7.
“Malassezin is really versatile, as it’s able to target hyperpigmentation, improve the skin’s moisture barrier and provide potent antioxidant protection without any irritation,” said Connecticut-based dermatologist Dr. Mona Gohara, who is also an associate clinical professor at Yale University. “The beauty of it is it’s gentle but also highly efficacious.”
In 2016, the same year the Einzigers filed a patent for their scientific discovery, the couple married. They are now parents to four children including a nearly one-year-old son. Because their courtship intersected with their scientific passion project, they consider Mother Science their fifth child.
“We had a lot of people who said, ‘You don’t want to do this. This is too hard. It’s going to take years.’” Simpson-Einziger said, pausing. “I remember thinking, ‘Years don’t scare me. I have a baby. I’m going to have to take care of a human for 18 years.’ There are no guarantees when you have a child how they’re going to turn out, but you do it out of love, out of passion, and it makes your life richer.”
While the couple continues to grow Mother Science’s product lineup, Simpson-Einziger is most proud of their process of discovery itself.
“We’re excited about contributing to science, and having that legacy as part of our brand,” she said.
She hopes Malassezin will one day be as universally known as Vitamin C and hyaluronic acid.
“I want people talking about Malassezin, not even about our brand, just about Malassezin,” she said.
In other words, she and her husband hope the ingredients of their products will be front and center — not themselves.
“Nobody is excited about coming to me for their skincare needs,” Einziger, who still regularly sells out stadiums with Incubus, said with a laugh. “I’m just a person who plays music who happens to be curious about the skin microbiome.”

Pope Francis goes electric in new eco-friendly popemobile
Pope Francis is going electric for the 2025 Jubilee processional, after being gifted an electric G-Class Mercedes-Benz popemobile by the automaker’s chief executive this week.
“We are moving towards zero emissions and are launching many electric products,” Ola Källenius told the Vatican. “This year we launched the electric G-Class.”
Källenius said the white, luxury convertible was specifically designed “paying attention to all the Holy Father’s needs.”
Francis has been using a wheelchair publicly since 2022 after a number of health issues.
Mercedes-Benz, which has been behind the popemobile since 1930, said it hopes the convertible “will provide the Holy Father with the comfort he needs for his travels.”
The “one-of-a-kind” pope transit vehicle comes equipped with finishes including a retractable roof and a rotating seat for Francis to greet audiences.
The popemobile is an iconic piece of Vatican imagery.
The car’s conversion to electric comes as the pope has repeatedly urged people worldwide to accept the science of climate change and work to protect the environment.
The Vatican says it plans to convert all of its vehicles to emission-free options by 2030.
Catholic Jubilees are celebrated every 25 years and are “precious times for taking stock of our lives, both as individuals and as communities,” Francis has said.
The 2025 Jubilee begins on Dec. 24 with the Opening of the Holy Door of Saint Peter’s Basilica, and runs through Jan. 6.

Flavor Flav Booted From Rockefeller Center After CEO Murder Boosts Security
Flavor Flav‘s all about fighting the power, standing up to NBC security … but, it seems they were just doing their jobs — ’cause we’re told he wasn’t expected at the tree-lighting, and security booted him.
Here’s the deal … Flav took to X to air some grievances about NBC kicking him out of the Backstreet Boys dressing room at the the Rockefeller Center tree lighting ceremony Wednesday night — despite all his work with them during the Olympics.
However, sources tell TMZ security had a very good reason to kick him out of the event … ’cause he wasn’t on the list of expected attendees.
We’re told Flav was at a party — not affiliated with NBC — nearby when he stopped in at the tree-lighting in Manhattan.
Our sources say security around the area was heightened because Brian Thompson — the UnitedHealthcare CEO — was gunned down about six blocks from where the tree-lighting took place … so, they’d shut down much of the area to protect the tree lighting guests.
TMZ.com
Despite this heightened security, it seems Flav somehow got past several layers of security into a holding area for the talent — he’s a charming guy, so it’s not totally shocking.
This is when security realized he wasn’t supposed to be there and, despite his celeb status, they quickly asked him to leave.
Our NBC sources tell us they’re huge fans of Flavor Flav … and, they’d love for him to attend the tree-lighting ceremony next year.
I posted and quickly deleted something last night,,, I was embarrassed by some language and actions by security guards throwing their weight around. The situation was poorly handled and I didn’t realize how many people would care. I thank all y’all for the love,,, and this the… pic.twitter.com/a3ROGmvGDH

Worth noting … Flav walked back his comments today — putting the blame on the security guards who kicked him out, instead of on the network itself.
We’ve reached out to Flav about this new information … so far, no word back.
