A founder letter · Lioren · Houston, Texas
How a working ICU nurse built the cream the lotion aisle wasn't going to make.
My name is Sarah. I've been a nurse for nine years. By my third year on the unit my hands had stopped looking like my hands. I tried what every nurse tries. None of it survived a full shift. So I went and read the actual research. And I built the thing the research said should exist.
Where this starts
I grew up in a small town outside Beaumont, Texas, in a house where everyone worked with their hands.
My mom was a CNA at the regional hospital for thirty-one years. My dad ran a small HVAC outfit out of the garage. I am the oldest of three. We were not poor and we were not comfortable. We were the family that knew exactly what every grocery item cost and exactly which bills were going to be late if anything broke that month.
I knew I wanted to be a nurse from the time I was about twelve. My mom would come home from a double, sit at the kitchen table without taking her shoes off, and tell us about the patients. Not the diagnoses. The patients. The eighty-six-year-old man whose wife came every day for six weeks. The teenager nobody visited. She talked about the work the way other people talk about a calling, because for her that's exactly what it was.
When I was seventeen, my grandmother went into hospice. The nurse who came to the house every afternoon, her name was Patricia, sat with my grandmother for an hour at a time, sometimes longer. Patricia did not rush. Patricia made my grandmother feel like the most important person in the room because to Patricia, in that hour, she was. I watched Patricia work for six weeks and I knew. That was the job. That was what I was going to do.
Memorial Hermann · Houston · 2017
My first unit was med-surg. My second was neuro ICU. By year three I was on the surgical ICU at Memorial Hermann and I was in love with the work.
If you have never worked an ICU, the cadence is hard to describe. You are not coasting. You are not reactive. You are five steps ahead of a patient who is, on a good day, holding steady, and on a bad day, falling. You wash your hands before you touch them. You wash your hands when you walk between rooms. You wash your hands when you doff a glove, before you put on the next one, after you write a note, before you draw a med, before you walk into a sterile field, when you come back from break. By the end of a 12-hour shift I was washing my hands somewhere between one hundred and forty and one hundred and eighty times.
I loved it. I want to be clear about that. I am not telling this story because I quit. I did not quit. I love the unit. I love the work. I love my coworkers. I love the patients I get to take care of. Nine years in and I would still trade most desk jobs for one shift on the SICU.
What I did not love was what was happening to my hands.
Year three · The hands
It started as redness across the knuckles. Then a tightness across the back of the hand that didn't go away between shifts.
By the end of year three I had visible cracks on every knuckle of both hands and a permanent split on the side of my right thumb that opened, and closed, and opened again, every week, for about eighteen months straight. The first hand wash of the morning made me catch my breath. The first sanitizer pump made me hiss into my mask. I started keeping the hand cream in my scrub pocket and putting it on between every patient, and it didn't matter, because the next wash took it off.
I tried CeraVe. I tried Aquaphor. I tried O'Keeffe's Working Hands and Eucerin and Vanicream and Curél and the Vaseline-and-cotton-gloves-overnight thing my grandma used to do. My dermatologist gave me a prescription steroid. I tried that too. The steroid worked for about eight days and then everything came back, plus my skin was thinner.
At the worst of it I had a moment in the staff bathroom where I stood at the sink, with the soap dispenser empty and my hands open under the faucet, and I cried. Not the dramatic kind of cry. The exhausted kind, where you don't have anything in you to make it stop. I had blood on the cuff of my scrub top from where my thumb had reopened. I was thirty-one years old and my hands looked like an eighty-year-old woman's hands.
I started hiding them. In photos with friends. At dinner with my husband's family. Holding my coffee with one hand wrapped over the other so the cracks weren't the first thing you saw. That's the part I want every nurse reading this to understand. I wasn't insecure about my hands. I was hiding the evidence that the job I loved was destroying me.
The graveyard in my drawer
By the time I started building Lioren, my bathroom drawer had eleven failed products in it.
CeraVe. Aquaphor. O'Keeffe's. Eucerin. Curél. Vaseline. The steroid. Two compounded creams a friend had recommended. A jar of straight shea butter. A coconut-oil tin somebody on TikTok said would work.
None of them was a bad product. They just weren't designed for the way my hands were being used. They were built around an ingredient list, not around the structure of skin under occupational stress. The category had decided what hand cream was, and what it was had stopped being enough about ten years before I needed one.
It is the most expensive drawer in my house and I learned more from it than from any single product I have ever used.
The day everything changed
In January 2023, infection control pulled me off the floor.
It is a thing that happens, although nobody wants to talk about it. If your hands have visible open fissures or active eczema, you can become a contamination route, both ways. You can carry pathogens in. You can carry pathogens home. The hospital had a duty. They put me on a two-week reassignment. Chart audit work. No bedside care. They said it was "until your hands heal." I said okay because I did not have a real argument.
I sat in a windowless office for fourteen days, doing chart audits, and what I felt was not embarrassment. It was anger. I was a good nurse. I was an experienced nurse. I had patients I loved. I had been pulled off the unit because of a cosmetic problem that, on the surface, should have been the easiest thing in the world to fix. It is hand cream.
Except it wasn't. None of it was working. I had spent six years on the floor washing my hands the right number of times the right way with the right products and the system the consumer category had built had no answer for it.
That was the night I went home and started reading the actual research.
The literature, not the lotion aisle
Most hand cream is built around what consumers respond to in a 30-second test in a focus group. It is not built around the structure of stratum corneum lipids in skin under occupational stress.
I read Peter Elias's papers from UCSF. I read the Bouwstra group out of Leiden. I read the dermatology consensus papers on the lipid bilayer of the stratum corneum, the 3:1:1 ratio of ceramides, cholesterol and free fatty acids, the role of the acid mantle and the pH at which the skin's own ceramide-assembly enzymes work. I read the niacinamide trials from the 2000s where 4% topical niacinamide was shown to upregulate the skin's own ceramide synthesis pathway.
What I learned is that the science was already there. None of this was a secret. It had been in the dermatology literature for fifteen, twenty years. It was just not in any product I could buy at Target.
The category had decided that hand cream was a paint job. The literature said hand cream, in the context of an ICU nurse's hands, needed to be mortar.
"Most creams sit on top of skin and wash off. The skin doesn't need topping up. It needs the mortar between the bricks put back. That is a different product."
Six months in my kitchen
I do not pretend to be a chemist. I am a nurse who could read a paper.
I started by reaching out to a cosmetic chemist named Maya in Austin who consulted for two of the dermatology brands I trusted. I sent her my reading list. I told her what I wanted. Ceramides, cholesterol and free fatty acids in 3:1:1 ratio, in a multilamellar W/O emulsion that would hold the bilayer geometry, buffered to pH 5.0, with niacinamide at 4% to push the skin's own pathway, panthenol to support repair, and not one ingredient that would not pay rent. No fragrance. No alcohol. No essential oil. No "optical brightener." Nothing that would sting on a fissure.
Maya looked at the brief and said, "This is more rigorous than what most clinical brands run." We took six months. I prototyped the application feel myself, on my own hands, on my coworkers' hands, on a charge nurse named Janelle who had sweated through three other "barrier creams" that year. We rejected the first four versions. The fifth one, in October 2023, was the one where Janelle handed me the empty 30 ml sample at the start of her next shift and said, "I need a real tube of this."
That was the first time I knew it was a product, not a project.
From a kitchen prototype to a real batch
In April 2024 we ran our first production batch out of a CGMP lab in Texas. 1,200 tubes.
I gave away 800 of them. To my own unit first. Then to a friend who runs the ER at a level-one trauma center in Austin. Then to a pediatric ICU in San Antonio. Then to two dental practices in Houston that had asked nicely. I asked one thing in return: tell me the truth, and tell me on day 3, day 7, and day 14.
The day-14 emails are the reason I am still running this company. Forty-one out of forty-seven nurses in our internal use study reported visible reduction in cracks and redness within fourteen days. Eight reported the sanitizer no longer stung within the first week. Three told me they had stopped hiding their hands.
I did not start a brand to sell hand cream. I started a brand because the day-14 emails from forty-one nurses I had given a tube to said the thing I had built was the thing the category was supposed to make and didn't.
What Lioren is now
Lioren is one product. It is the cream I built because the lotion aisle was not going to make it.
It is sold in a tub that looks like the cream every nurse already has in her break-room drawer because that silhouette is the silhouette my tribe trusts. We chose it on purpose. The trust earned by another brand's tub is borrowed, then we have to keep it. So far the day-14 emails say we are.
I still work the unit. I'm at Memorial Hermann four shifts a month. The other days I work on Lioren. I am the only person in the company who has been pulled off a floor for cracked hands and I am not letting another nurse get pulled off a floor for the same reason if I can help it.
If your knuckles are bleeding by the end of your third shift in a row, the cream you have been using is not the one. Try this one. If it does not visibly reduce cracks and redness in fourteen days, send the empty tube back. We refund every penny and we keep the empty tube.
I would rather lose the twenty dollars than be one more cream you stopped trusting.
With respect,
Sarah
