Where each label stops telling you the dose

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. 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).
