The skin shelf that got shorter
After a year of swapping serums every two weeks, one user kept their routine still for twelve weeks — and let AI read the photos.
Context
A bathroom shelf full of half-used actives, a face that looked roughly the same, and a feeling that every TikTok recommendation had cost €30 and led nowhere measurable.
The shift
They froze the routine, took one weekly photo in the same light, kept a 1-line daily skin note, and asked AI to compare months instead of days — with one new active introduced as a single 12-week variable.
Approach (in shape, not in recipe)
A vendor-neutral skin ledger of photos, notes, and ingredients, read across the realistic 12-week clock that skin actually runs on rather than the 7-day clock the feed runs on.
What an honest observer would notice
Two-thirds of the previous routine turned out to be redundant or actively irritating; the single retinoid trial showed visible change at week 10; the shelf shrank from fourteen products to five.
