How Stella Works
Skin intelligence in three steps
Not a recommendation engine. Not a diagnostic tool. Stella scans your skin, connects to your health data, and shows you what's actually changing over time.
01
Scan in 30 seconds.
Hold your phone to your face. Stella reads 130+ signals and starts building your baseline.
02
See what's behind it.
Connect your sleep, stress, and cycle data. When your scores shift, you'll see what else changed.
03
Decide with data.
Your weekly report shows exactly what's shifting. Change your routine, your products, or nothing. Do it knowing.
What makes Stella different
Tracking, not one-off scanning
Most skin apps give you a single snapshot. Stella tracks your skin over weeks and months. The value is in the trend, not the moment.
Context from your wearable
Sleep, stress, cycle, activity. Stella connects to Apple Health, Oura, WHOOP, Fitbit, Samsung Health, and more to show you what's behind your skin changes.
26 metrics, not a score
Stella doesn't reduce your skin to a single number. It tracks 26 independent metrics across sensitivity, clarity, tone, aging, eye area, and baseline properties.
Observation, not prescription
Stella shows you what's happening. It doesn't tell you what to buy. The decisions are yours, informed by data instead of guesswork.
See what your skin has been trying to tell you
Your first scan takes 30 seconds. Your first weekly report arrives in 7 days. The pattern starts becoming visible from there.
