Purge vs Breakout Log

XLSXSHEETS
A daily skin log and a product-introduction timeline on the same axis, so the weeks count themselves.
When you introduce a product you add it with its date, up to four at once, though fewer is better and one at a time is best. Then each day is one row: the date, a state from the dropdown, and a note if something is worth noting. Ten seconds. Miss days freely, because the timeline is made of dates rather than streaks and a gap changes nothing.

WEEKS SINCE
When skin acts up, the question is always how long after the new product this started, and the honest answer is almost never available, because nobody remembers the date they opened a bottle. Here the weeks-since column is computed from the introduction date you typed, sitting in the same row as the state you logged that day. You are reading a timeline rather than reconstructing one, which is the difference between a pattern and a story you told yourself.
