🔦 @lumeriaskin (YC S26) is building a handheld camera with a UV light that clips onto your phone so you can scan you skin, detect breakouts days before they show up in the mirror, and monitor wrinkles changing over time. Think about it like an Oura Ring for your skin.
Most people stack product after product on their faces and never really understand what is working and what isn't. Lumeria scans your skin with the same kind of light used in clinics. The app tracks how your skin changes over time and gives you personalized product and habit recommendations. They sold out their first batch and did $200k in the first month, with early press from Forbes, Fitt Insider, Her Hustle, and Wellworthy.
@malhalla06 and @TheAntheaGuo are both Berkeley engineers. Anthea worked on Computer Vision at Google, grew up in Shenzhen and is actively negotiating the product, fast-tracking the development process. Maryanne has already exited her first spectroscopy biotech startup at the age of 17 and has 25 million views as an influencer herself! @pioneer_fund is very excited to back these two!

Everyone owns skincare products, but nobody knows what's actually working.
Today, @theantheaguo and I launch @lumeriaskin (YC S26) to end that.
The Lumoscope is a multispectral camera that clips onto your phone and scans your skin at home with the same light used in clinics, so you see what a mirror can't: a breakout days before it surfaces, and sun damage years before it shows.
Every scan is scored on hydration, redness, texture, and sebum, and it compounds into a record of your own skin. Lumi reads that history, connects flare-ups to causes you'd never suspect, and matches products to YOUR data, instead of a population average.
Preorders are officially open today at $199 only until Aug 16th. Starting today, skincare will no longer feel like guessing. ☀️

Just preordered my @lumeriaskin Lumoscope at the early price. Been trying to figure out what's actually going on with my skin for years with no real answers — hoping this finally gives me data instead of guesses. Excited to be an early supporter @malhalla06 @TheAntheaGuo 💛

Calling it now, this will be a Unicorn. No way in hell it fails. Absolutely insane.

survived @ycombinator demo day by running a skincare competition at our booth
we scanned over 150+ investors only to tell most of them their skin isn’t doing great 😭 (a hot auditorium and open bar means bad news for dehydrated skin and redness!)
woke up to an inbox filled with hundreds of investor emails. turns out that’s how you get inbound 🙂↕️

It's YC S26 Demo Day tomorrow. Some of the wildest ideas in this batch:
→ @Atomarine_co .... floating data centers on barges at sea, cooled by seawater, aiming to run on nuclear ships. Their logic: grids can't expand fast enough, the ocean can.
→ @KaraLabsAI .... diamond semiconductors. Today diamond sits next to the chip to cool it. Their bet: tomorrow diamond is the chip.
→ @ParasmaAI .... training living human brain cells to compute. The founder got here via a project teaching neurons to play Doom.
→ @LambLabs .... hard-coding an entire AI model directly into silicon. Claiming 20,000+ tokens/sec in some configs.
→ @Locke .... AI for navigating government. Zero to ~$800K ARR in eight weeks, reportedly on track for $1M by Demo Day.
→ Axelrod .... AI-run hotels whose agents click through the ancient front-desk software the way a human would. Lack of APIs in hotels is the moat.
→ @Omantahealth .... a personal scientific R&D team for one patient. Started in oncology, chasing individualized treatment.
→ @Exosat_ .... a politically neutral, sovereign satellite network. The founder joined YC on the logic that if it lifted his odds of building a Starlink-scale company by even 7%, the equity was worth it.
→ @lumeriaskin .... at-home skin imaging. $100K+ in revenue in under 48 hours
Two-person teams, most of them, pointing AI at tangible stuff - chips, oceans, satellites, biology.
Say what you want about YC. This is not a batch of chatbot wrappers.
Thank you to @Forbes and @dasha_shunina for featuring Lumeria!

Demo Day of @ycombinator S26 batch is next week.
A sneak peek at what founders are building:
Floating data centers.
Diamond semiconductors.
Biological computers.
It isn’t how much AI is in it. By now, that’s almost expected.
Big question: What becomes possible because AI now exists?

We wanted a launch video that highlighted authenticity through real skin and real struggles. So happy that we delivered, and can't wait to bring Lumeria into people's homes this Fall! Preorder now☀️
last week, @theantheaguo and I launched our YC startup @lumeriaskin, earned 2m+ views across platforms, and sold out our first batch in <24 hours.
the video took over two weeks to make and lots of heart, soul, & late nights. here's how we did it. 💛
So grateful for everyone resonating with our mission! Quick before batch 2 runs out 🏃💛
The first batch of the @lumeriaskin Lumoscope sold out almost instantly, way beyond what we anticipated. Thank you for the overwhelming support! 💛
The second batch is now live on our website.
Expected delivery: Mid to Late Fall, great as a gift! ☀️
We just launched! ☀️🧡

tomorrow, @lumeriaskin comes out of stealth and will be officially launching as part of the @ycombinator s26 batch.
@theantheaguo and I are building the lumoscope: the first at-home skin camera that sees in visible, polarized, and uv light.
it clips onto the phone you already own and shows what everyday photos smooth over: wrinkles, breakouts, redness and how it all changes week over week.
understanding your skin should be accessible, personal, and honest. starting tomorrow, people will no longer have to guess through skincare and anyone can own their skin's story. 💛
thank you to @bosmeny and @borisjabes for believing in us.

We applied to @ycombinator 30 seconds before the deadline, had 5 major typos we couldn't edit after, and watched people on X get interviews within days while we heard nothing (thought it was joever).
1 month later, I was booking a highly overpriced, last minute flight to be in SF for <24 hours to interview with @bosmeny and @borisjabes!
And now, we're more than 1 month into grinding out the S26 batch :)
F26 applications are due tonight. Apply, no matter how rough the application is or how late! You never know what kind of miracles happen overnight.
Attached is the 67th take of our founder video in my Berkeley dorm common room (had a resident ask why she heard the same script a million times across 4 days). Your journey can truly start anywhere :p

three months ago I was still planning my fall classes at Berkeley.
today, I’m dropping out of my Bioe degree at 19 after getting into @ycombinator to build the Oura Ring for Skin.
Skincare is a guessing game. @Lumeria_Skin is a multispectral camera that clips onto your phone, analyzes your skin beneath the surface, and turns guesswork into personalized product & lifestyle recommendations.
we’re unbelievably grateful to be working with @bosmeny @borisjabes
& we absolutely can’t wait to glow up the tech world ✨🙃
