Redness and Sensitivity
Is your skin getting more reactive, or was today just a bad day?
Redness can be temporary (a hot shower, a new product, a stressful day) or it can be a trend (increasing sensitivity over weeks). Without tracking, you can't tell the difference. Stella separates the signal from the noise.
What Stella observes
Stella tracks redness levels, visible capillaries, PIE (post-inflammatory erythema), and sensitivity patterns. Over time, these reveal whether your skin is becoming more reactive or whether individual flares are isolated events.
What tracking reveals
Whether redness is trending up or just flaring
A single red morning means nothing. Redness that's been climbing for three weeks means something. Tracking shows you which one you're dealing with.
Whether your barrier is weakening
Increased sensitivity often follows barrier compromise. If hydration is dropping while redness is rising, the pattern points to barrier function.
How your skin responds to weather and environment
Cold wind, dry air, UV exposure. Stella correlates your redness scores with environmental conditions so you can see what triggers your skin.

One scan captures the baseline. Weekly scans show the trend. The pattern is the part you can't see without data.
