Which SeneGence products carry peptides, and what do they do?

Quick answer

SeneGence puts peptides where each beauty goal lives: Caprooyl Tetrapeptide-3 in GLP Complex™ and SeneCell™ for smoother-looking lines, a tone-care peptide pair in every DayTime and Evening Moisturizer, Palmitoyl Tetrapeptide-50 with Heptapeptide-15 Palmitate in Lip Line Corrector, and Acetyl Tetrapeptide-3 with clover for fuller-looking brows, lashes and hair. Lip Line Corrector visibly improves the appearance of vertical lip lines by up to 30% after six weeks of twice-daily use in an independent clinical study of 35 women ages 40–70, measured by expert grading against baseline. In an independent study of 31 participants measured by image analysis, GLP Complex™ with SenePlex+® and Exosomes reduced the appearance of deep wrinkles by 11.2% at four weeks and 23.4% at eight weeks, and improved the look of facial volume by 8.4% at eight weeks.

Peptides are short chains of amino acids, and each one is chosen for a specific visible job. Do peptides work on skin? explains how they fit a routine.

What do SeneGence’s own clinical studies show?

Peptides work inside finished formulas, and SeneGence measures those formulas. Results can also arrive fast. One hour after a single application, NeoTight® Rejuvenating Anti-Wrinkle Serum improved measured net skin elasticity by 7.65% in an independent study. See the GLP Complex study, Beauty Book 2026 (p. 18) and the NeoTight Rejuvenating study. Each peptide in the table links to its ingredient maker’s own research.
