About this ingredient
sh-Polypeptide-9 (INCI Nicotiana Benthamiana sh-Polypeptide-9) is a recombinant peptide grown in the tobacco plant Nicotiana benthamiana through biotechnology. In anti-aging cosmetics it is positioned as a plant-derived growth factor aimed at skin firmness and renewal. Here it is worth being honest about efficacy. The maker links the peptide to renewal and firmness, but independent data is scarce: most studies come from the side that sells it. Count on it as a promising support component, not as an active with proven efficacy. Applied topically it is not systemically relevant, so it can be used during pregnancy and breastfeeding without issue. Tolerability is good. Irritation and allergy potential are both low, which makes it suitable for sensitive skin. There is no data pointing to comedogenicity.
