Hydrolyzed sr-(Polypeptide 168 Oligopeptide 178) Description

Hydrolyzed sr-(Polypeptide 168 Oligopeptide 178) is a lab-engineered peptide. This vegan silk polypeptide is derived via fermentation. Applied to skin, it provides an invisible shield against environmental threats – such as pollution, UV, and blue light. As such, it’s considered a film-forming agent with humectant (water-binding) properties.

This peptide works as a barrier and carrier, protecting from moisture loss while aiding the performance of other ingredients. It supports moisture barrier repair, helps reduce factors in skin that degrade collagen, and visibly revive skin’s radiance.

Due to its design, hydrolyzed sr-(Polypeptide 168 Oligopeptide 178) also makes a significant contribution to the aesthetics of products such as moisturizers, eye creams, and serums. 

Clinical data from tests run by the supplier has shown improvements in skin’s firmness, wrinkles, elasticity and texture along with visible lifting of the mid-face area.

Use levels of hydrolyzed sr-(Polypeptide 168 Oligopeptide 178) in skin care range from 1–2%. It’s considered a biodegradable ingredient.

Fun fact: Oligopeptides are short-chain peptides, typically containing 2–10 amino acids. Polypeptides are larger, typically built of 20–50 amino acids. Combining these helps deliver peptides (or their signals) to various parts of skin.
