Why those two numbers

The peptide sits at 5 parts per million. The published trial on this peptide used it at 3 parts per million, for 12 weeks, on 93 women, and measured lower wrinkles and fine lines against the same cream without it.

No published trial has run this peptide at 5. So the number says there is more of it in here than there was in the study, and it does not say the result will be bigger. It is printed so you can check it against the trial instead of guessing.

The niacinamide sits at 5%, which is the strength used in a 2005 trial of 50 women. Both studies are named in full at the bottom of this page.
