19. CEO @lumeriaskin ☀️ (YCS26) Your skin has a story. I'm building the tech to finally read it.

[Maryanne Alhallak @malhalla06]

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. ☀️

@callumhyman24 surprised @lumeriaskin is not up there 🤔💫

[Lumeria (YC S26) @lumeriaskin]

From Berkeley to YC to @TechCrunch Disrupt! ☀️

Our co-founders Maryanne and Anthea had the honor of speaking with @SutardjaCenter alongside an incredible lineup of founders and innovators!

They shared their journey building Lumeria, the lessons learned along the way, and one big message: build the startup of your dreams, not anyone else's. 💛

[Kevin Liu ᝮ @kevskgs]

The alpha in hearing from founders is the privilege of learning about the dedication, attention to detail, and mentality required to build from dusk to dawn, move fast, iterate on feedback, fix issues, choose what to build, when to build something new, face crossroads, raise, hire, network, and more every single day.

These, and more, were the best insights at @TechCrunch Disrupt 2026: @malhalla06 and @TheAntheaGuo on how they built @lumeriaskin.

[Lumeria (YC S26) @lumeriaskin]

Lumeria was everywhere during SF Tech Week! ☀️

Our founders barely got any sleep as we sponsored three events, met tons of new people, and got to show off the Lumoscope at each one. Here’s a recap of what we were up to:

🍒 Cherry on Top: We kicked things off at Cherry's sold-out anti-networking launch party at Novela, where the one rule was don't ask anyone what they do for work (unsurprisingly being in SF, it was ignored every time!). Luckily, nobody said anything about asking about people’s skin. Our co-founders were still scanning faces and chatting with people until 2 AM.

🎭 Masquerave: A few days later, we headed to Circe's masked kickoff party, full of speakeasy vibes and a room of founders, operators, and investors. Our favorite part was seeing people's reactions when they discovered what the Lumoscope can reveal underneath the surface!

💡 Talk to Users Hackathon: We wrapped up the week at Sense AI's 12-hour hackathon, where 20 teams built and tested with real users. Along with offering scans, our co-founder Anthea mentored teams alongside a16z speedrun and YC founders.

A huge thank you to Cherry, Circe, and Sense AI for having us, and to everyone who stopped by to chat. We loved getting to show off the Lumoscope in preparation for our shipments this winter, and we can't wait for the next event we’ll be at!

@kevskgs @generaltxn this is so helpful! literally a design wizard with how many projects you ship just for the good of all 🙏

🔦 @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!

[Maryanne Alhallak @malhalla06]

@kevskgs @Princeton @drfeifei the world is changing faster than ever before

[Maryanne Alhallak @malhalla06]

@RamG_4 @TheAntheaGuo @lumeriaskin Yes, real data we are collecting and annotating through clinical partners to fine tune our own models for accuracy. :)
