Where each label stops telling you the dose

15 of 28 sit below the line, marked by Phenoxyethanol. Including what it is sold on: Hydrolyzed hyaluronic acid.
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.
