What's in one but not the other

What each one adds acts on The stratum corneum, Not established for The Ordinary Caffeine Solution 5% + EGCG Eye Serum 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.

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.

What the scene shows

The Ordinary Caffeine Solution 5% + EGCG Eye Serum is placed by Glycerin (the stratum corneum), Hyaluronic acid (the stratum corneum), Lactic acid (the stratum corneum). The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation) is placed by Glycerin (the stratum corneum), Hyaluronic acid (the stratum corneum), Crosslinked sodium HA (the stratum corneum). A layer is where an ingredient does its work, never how deep it travels, and never a claim about how well it works.
