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 cross-section at the top of this page is not decoration and not a diagram of the skin in general: it places the molecules these two are sold on at the layer each is understood to act on. La Roche-Posay Hyalu B5 Suractivated Serum is placed by Glycerin (the stratum corneum), Pro-vitamin B5 (the stratum corneum), Hyaluronic acid (the stratum corneum). The Ordinary Niacinamide 10% + Zinc 1% is placed by Niacinamide (the living epidermis), Zinc PCA (not established), Pentylene Glycol (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.
