Caprooyl Tetrapeptide-3 with Dextran — wrinkle and skin-support studies

in the study

Manufacturer studies of Caprooyl Tetrapeptide-3, including human serum studies of the full Glycerin, Water, Dextran, and Caprooyl Tetrapeptide-3 material

what it showed

In a manufacturer’s randomized, placebo-controlled split-temple study in 27 women ages 40–65, a serum containing 2.5% of its Glycerin, Water, Dextran and Caprooyl Tetrapeptide-3 material produced a 16% average reduction in the appearance of fine lines and wrinkles at day 28, measured from silicone replicas after twice-daily application.

GLP Complex™ with SenePlex+® and Exosomes, SeneCell™ SenePlex+® StemCell Concentrate, and MakeSense® Silk Primer & Pore Minimizer contain Caprooyl Tetrapeptide-3 with Dextran, chosen for smoother-looking skin and softer-looking fine lines and wrinkles.

The shared peptide system connects GLP Complex™, SeneCell™, and MakeSense® Silk Primer & Pore Minimizer around smoother-looking lines and firmer-looking skin; choose among them by the serum, concentrate, or primer job you need.
