← What Stella Tracks

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.

Common questions

Can Stella detect rosacea?

No. Stella tracks the visible appearance of redness, not the underlying condition. If you have persistent or worsening redness, please consult a dermatologist.

How does Stella track sensitivity?

Stella doesn't directly measure sensitivity. It tracks indicators like redness, barrier hydration, and reactivity patterns that often correlate with increased sensitivity.
