Your 28-day Centella routine diary.
A skin cycle lasts about 28 days. This diary helps you follow yours: log your routine, note how your skin feels, and get gentle reminders to come back at the moments that matter — week 1, week 2, and the end of your first cycle.

Why 28 days?
Skincare is a cycle, not a single moment.
New skin cells take roughly 28 days to travel to the surface. That is why patience matters: visible changes from a gentle Centella routine usually appear gradually across your first cycle. Use this diary to stay consistent, not to expect overnight results.
