See Stella — Skin Intelligence That Reads 130 Signals in 30 Seconds

What does Stella actually measure?

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.

How long does a scan take?

About 30 seconds. You use your phone camera in good lighting. No special equipment needed.

How accurate is it?

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.

Does lighting matter?

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.

How often should I scan?

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.

Does Stella tell me what products to use?

Stella gives you observations about how your skin looks over time. You decide what to do with that information. The agency stays with you.

How much does it cost?

Stella is free to try. No credit card required to start scanning and tracking your skin.

What happens to my data?

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.
