About this ingredient
Nicotiana benthamiana sh-polypeptide-5 (same INCI) is a recombinant peptide produced in tobacco plants through biotechnology. The manufacturer presents it as a signaling peptide for skin renewal and firmness. Here it pays to be clear about efficacy. Signaling peptides are a promising category, but for this specific peptide the independent data is sparse and leans mostly on supplier information. Count it as a supporting active with still-limited evidence, not a guaranteed result. During pregnancy and breastfeeding it is fine to use topically. Tolerance is good: low irritation and low allergy potential, suitable for sensitive skin. An individual reaction is possible but uncommon.
