What's in one but not the other
The two labels share 0 of the 30 ingredients between them. The actives are where they part company.
What each one adds acts on The stratum corneum for Bioderma Sébium Gel Moussant and The stratum corneum, The living epidermis for Cetaphil Gentle Skin Cleanser. 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 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. Bioderma Sébium Gel Moussant is placed by Lactic acid (the stratum corneum), Xylitol (the stratum corneum), Mannitol (the stratum corneum). Cetaphil Gentle Skin Cleanser is placed by Glycerin (the stratum corneum), Niacinamide (the living epidermis), Pro-vitamin B5 (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.
