Which keeps longer
a tube and two light-sensitive actives: the packaging is doing work here.
where this comes from
The pack form is read off the packshot; the light-sensitive actives are the base's photostability rows, sourced on each glossary page; the period after opening (not printed) is read off the maker's page, never a reseller's. Catalogue checked September 2026.

Where each label stops telling you the dose
Ingredients are listed in order of how much is inside, but only down to 1%. Below that the brand may list them in any order it likes, so the bottom of a label is a set, not a ranking. These two stop being a ranking in very different places.

Below the line is not too little to work: ceramides, retinoids and peptides all act far under a percent. It means the position stops carrying information. Where the line falls is inferred from the first ingredient whose whole job is done at a fraction of a percent, so it is a close read of the label rather than a number from the formula sheet.
