Do peptides actually work on skin?
Yes—peptides can support visible cosmetic changes, but the peptide and the finished formula have to match the result you want. Manufacturer studies here report smoother-looking lines, firmer-looking skin, fuller-looking lips, and brow, lash, and hair support. SeneGence uses peptides across skincare, lip care, brows, lashes, hair, and makeup.

Which peptide fits the result you want?
- Smoother-looking lines and firmer-looking skin: Caprooyl Tetrapeptide-3 with Dextran appears in GLP Complex™ with SenePlex+® and Exosomes, SeneCell™ SenePlex+® StemCell Concentrate, and MakeSense® Silk Primer & Pore Minimizer.

For the full Butylene Glycol, Water, Dextran, Acetyl Tetrapeptide-3, and Trifolium Pratense (Clover) Flower Extract material, the manufacturer reports up to 27% lash-density improvement with a 93% responder rate at week 8 in a 17-woman split-eye study of a 2.5% material gel versus opposite-eye placebo, used morning and evening. See the hair and lash evidence.
- More even-looking tone: Palmitoyl sh-Octapeptide-24 Amide with Palmitoyl sh-Tripeptide-5 Norisoleucyl sh-Nonapeptide-1 appears in DayTime Moisturizer - Dry, DayTime Moisturizer - Normal to Dry, DayTime Moisturizer - Normal to Oily, Evening Moisturizer - Dry, Evening Moisturizer - Normal to Dry, and Evening Moisturizer - Normal to Oily—the six formulas whose current US ingredient lists verify both peptide names. The ingredient manufacturer describes Palmitoyl sh-Octapeptide-24 Amide with Palmitoyl sh-Tripeptide-5 Norisoleucyl sh-Nonapeptide-1 for more even-looking tone and lighter-looking dark spots. It also reports a 56-day study of the pair. See the two-peptide role.
- Smoother, firmer, more radiant-looking night care: Nicotiana Benthamiana Hexapeptide-40 sh-Polypeptide-76 appears in the current US formulas of Evening Moisturizer - Dry, Evening Moisturizer - Normal to Dry, and Evening Moisturizer - Normal to Oily. The ingredient manufacturer describes producing this fusion peptide through Nicotiana benthamiana biotechnology and vertical farming. In a 20-woman, placebo-controlled split-face study of Nicotiana Benthamiana Hexapeptide-40 sh-Polypeptide-76, the ingredient manufacturer used a preparation containing 2% material, applied twice daily. At day 28, it reported 16% lower wrinkle count, 11% lower wrinkle volume and 14% lower wrinkle depth across the full study group. Within the separate 85% responder group, wrinkle depth was 19.4% lower on average. Open the study.
- Multi-factor smoothing and visible renewal: sh-Oligopeptide-1, sh-Oligopeptide-2, sh-Polypeptide-1, sh-Polypeptide-9, and sh-Polypeptide-11 appear together in Advanced SenePlex+® Renewal Serum with Retinol. Using PRIMOS Lite 3D to measure crow’s-feet after use of a cosmetic formula containing sh-Oligopeptide-1, sh-Oligopeptide-2, sh-Polypeptide-1, sh-Polypeptide-9, and sh-Polypeptide-11, the manufacturer reports appearance improvement of 10% at two weeks and 21% at four weeks. See the five-factor findings.

For a facial routine, start with cleansing, then follow each chosen product’s directions and add only the treatment steps your skin and routine call for before moisturizer and eye care. In the morning choose DayTime Dry, Normal to Dry, or Normal to Oily. In the evening choose Evening Dry, Normal to Dry, or Normal to Oily. For lashes, let UnderSense fully dry, then finish with one VolumeIntense Mascara or VolumeIntense Waterproof Mascara.
