Why would I need this?

Dry-skin weather often arrives before your routine changes.

You may notice the tightness later, but the environmental setup starts earlier: outdoor air gets drier, buildings exchange that air, heating lowers indoor relative humidity, and skin loses water more readily.

Cold or dry weather

Seasonal weather controls how much water vapor enters a home.

Building properties

Humidity changes

Indoor humidity changes in response to vapor buffering by building materials and heating.

Stronger drying gradient

The driving force for moisture loss becomes stronger around the skin.

Still not sure the signal matters?

Compare Boston and Miami in winter. The contrast makes the DSI tangible: location can change the indoor drying burden, which changes how useful a weekly care cue can be.
