Peptides & Biomimetic Proteins
Short chains of amino acids that signal skin cells — now appearing across all product categories from concealers to eye patches. Bio-engineered peptides as delivery systems are one of the most significant formulation developments of 2025–2026; biomimetic peptides arrive with improved purity and a lighter environmental footprint.
Benefits
- cell signalling for repair and firming
- can act as targeted delivery vehicles
- well-tolerated across skin types
Example uses
- eye treatments (caffeine + tetrapeptide)
- concealers with active claims
- barrier serums
Formulation notes
Pairs cleanly with caffeine, sodium PCA, and glycerin (per Rhode's October 2025 Peptide Eye Prep formulation).
Watchouts
Peptide naming is opaque — ask which peptide, at what concentration, and what study supports its claim.
INCI & aliases

Clean beauty perception
Strongly positive when the specific peptide and study are disclosed.
