Hydration
Your skin is drier than you think. Or is it?
Hydration is one of the most volatile skin metrics. It shifts with weather, sleep, products, and even the time of day. The question isn't whether your skin is dry right now. It's whether your hydration baseline is stable, improving, or declining. Stella tracks the trend.
What Stella observes
Stella tracks surface hydration levels across different facial zones. Over weeks, this builds a hydration baseline that shows you how your skin retains moisture under different conditions.
What tracking reveals
Whether your moisturiser is actually working
You've been using the same moisturiser for six weeks. Are your hydration scores higher than before you started? Tracking gives you the answer.
How weather affects your hydration
A drop in humidity doesn't just feel different. It shows up in your scores. Stella lets you see exactly how your skin responds to seasonal shifts.
Whether dryness is temporary or a new baseline
A dry week might be noise. A dry month is a signal. Tracking shows you which one you're in.
