What's in one but not the other
The two labels share 4 of the 45 ingredients between them. The actives are where they part company.
What each one adds acts on The living epidermis, The dermis, The stratum corneum for Celimax The Vita A Retinal Shot Tightening Booster and The stratum corneum for The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation). That is the layer each is understood to act on, not how deep it travels.
Only in Celimax The Vita A Retinal Shot Tightening Booster
Only in The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation)
The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation) is a different bottle only for: hyaluronic acid, crosslinked sodium ha, pentylene glycol.
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.
a dropper bottle and nothing on this label that light breaks; the period after opening not read yet.
The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation) is the one to keep if you use it slowly: a dropper bottle, nothing on this label that light breaks.
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.
