The Problem
Most skincare is guesswork.
You follow a routine. You try products people swear by. And you never really know what's actually working, or why.
A Different Approach
A clearer picture of your skin.
Not a recommendation engine. Not a diagnostic tool. Just the data you need to make your own calls.
Scan in 30 seconds.
Hold your phone to your face. Stella reads 150+ signals and starts building your baseline.
See what's behind it.
Connect your sleep, stress, and cycle data. When your scores shift, you'll see what else changed.
Decide with data.
Your weekly report shows exactly what's shifting. Change your routine, your products, or nothing. Do it knowing.
No credit card required.
The Bigger Picture
Your skin doesn't exist in isolation.
Sleep quality, stress patterns, and cycle data may show up in your skin scores. Stella connects to your existing health data so you can see the full picture, not just the surface.
Works alongside Apple Health · Fitbit · Oura · Whoop · Samsung Health · and more

Add the products you use. Each week Stella connects your routine to your scores. When your skin changes, you'll see what may have influenced it, and when.

The Science
"The goal was always simple: show you what's there."
Every metric Stella tracks starts with a question: can we measure this accurately from a phone camera? If the answer is yes, and the data is meaningful, it makes it into the app.

What People See
“The product recommendations are genuinely spot on. I followed the app's advice and added retinol to my evening routine, and the change in my skin was visible pretty quickly. What I love most is that I can actually track and see this transformation through the app every day, which keeps me consistent and motivated. It feels like a smart, practical way to keep improving how you look over time. A really powerful tool for anyone serious about their skin.”
“I love this app! I've been scanning for a couple of months and it's been really cool to see how my skin responds to different products that I have tried. I also just started using the skin journal that tracks my habits throughout the day so I'm really excited to see how my day to day also affects my skin.”
“I love using this app because it has shown me how to optimize my skincare products effectively so that I'm getting the best results. It also recommends budget friendly products that I should consider to make my skin look better.”
“Awesome app, learning things about my skin that I didn't know about.”
"We built Stella because we wanted to understand what our routine was actually doing, and see it in the data."
The products you love are still yours. Stella just gives you the layer underneath, so you can see what's shifting, when, and why. If you're curious about whether it's right for you, try Stella for free.

Questions
Common questions.
Stella reads 26 metrics across six categories: sensitivity, clarity, tone, pigmentation, aging, and eye area. Each metric tracks a specific aspect of how your skin looks.
About 30 seconds. You use your phone camera in good lighting. No special equipment needed.
Stella's scans are designed to be consistent and comparable across sessions, which is more useful than any single "accurate" number. What matters is how your scores move over time, not the absolute value on day one. The more you scan, the more meaningful the data becomes.
Yes. Consistent lighting gives you the most comparable results. Stella works best in natural, even light (like near a window). Scanning in the same spot each time helps your trends stay meaningful. The app will let you know if conditions look off.
Most users scan two to three times per week. The more data Stella has, the more meaningful the patterns it can surface in your weekly reports.
Stella gives you observations about how your skin looks over time. You decide what to do with that information. The agency stays with you.
Stella is free to try. No credit card required to start scanning and tracking your skin.
Your scans are processed to generate your skin scores and stored securely. We never sell your personal or biometric data. Anonymised, aggregated insights may be used to improve Stella's accuracy over time. Nothing that identifies you.
No. Stella makes appearance-level observations about your skin. It does not diagnose, treat, or assess any medical condition. If you have a skin concern, please see a dermatologist or healthcare professional.
