00:00:05,458 --> 00:00:11,333
One published cosmetic trial tested pal-KTTKS, a defined five-amino-acid sequence with a lipid

00:00:14,833 --> 00:00:19,500
Ninety-three women participated in a twelve-week, randomized, double-blind split-face study.

00:00:19,500 --> 00:00:24,958
Researchers compared a moisturizer containing pal-KTTKS with the same moisturizer without it.

00:00:24,958 --> 00:00:30,417
The tested formulation improved fine-line and wrinkle measurements relative to the control.
