I keep a ridiculous spreadsheet: cost per mg, days between shipments, whether the cold pack actually arrived cold. Last month I added a throwaway column labeled "face." My chin and cheeks used to flake through foundation by 2pm — same cheap cleanser, same moisturizer, same water bottle the whole time.
Lately I blot once instead of three times, and foundation sits flat instead of catching on dry patches.
Could be less sugar, could be fewer greasy takeout nights, could be that I genuinely hydrate now. No idea. But it's held steady across my last two refills, which is longer than any skincare product I've ever stuck with.
It's the first non-scale change I've bothered to log, and honestly it made me reread my own notes for things I'd ignored.
Anyone else keeping odd side-columns in their tracking? What showed up before you were looking for it?
