Start Dermidia Guide Lite
Save your local Dry Skin Index dashboard with a secure email link. Guide Lite includes current DSI, this week's forecast, your bounded 52-week context review, and an optional weekly care cue.
Weekly, when it matters
The Dry Skin Index is a slow seasonal signal, so one weekly cue — not constant pings — is the practical cadence for staying ahead of drying weeks.
Backed by peer-reviewed science
The DSI quantifies indoor drying stress from temperature and humidity. Level 4 is the published threshold where dry-skin formation begins.
