Formulation Deep Dive

Peter Thomas Roth Peptide Skinjection Fill + Fix Under-Eye Cream is engineered as a high-performance, silicone-in-water emulsion designed to provide immediate optical blurring and long-term structural support to the delicate periorbital region. The base utilizes a sophisticated chassis of Dimethicone and Polysilicone-11 to create a breathable, velvet-finish film, while Glycerin and Butylene Glycol serve as the primary humectant system to ensure sustained epidermal hydration. Active performance is driven by a synergistic blend of Sh-pentapeptide-5 (Peptilift) for targeted collagen support, Bellis Perennis (Daisy) Flower Extract to address melanogenesis-induced dark circles, and Caffeine for its vasoconstrictive properties to reduce localized edema. The formula further incorporates Sodium Hyaluronate and Glucomannan-filled Hyaluronic Acid Filling Spheres (Trihydroxystearin and Ethylhexyl Palmitate) to provide a localized plumping effect via hygroscopic expansion. The complex matrix is stabilized through a robust silicone emulsifier network featuring Cetyl PEG/PPG-10/1 Dimethicone and PEG/PPG-18/18 Dimethicone, while the preservation system relies on a broad-spectrum blend of Phenoxyethanol, Sodium Benzoate, and Potassium Sorbate to maintain formula integrity.

Preservative Chelating Agent
Citric Acid GOOD
Acts mainly as a pH adjuster and buffer and as a chelating agent that protects formula stability and preservation; at higher leave-on levels it also serves as a mild exfoliating AHA.
Chelating Agent Exfoliant
Trihydroxystearin NOT RATED
Ethylhexyl Palmitate GOOD
A light emollient ester used for a silky feel, easy spread and pigment dispersion.
Emollient
Lauryl Glucoside GREAT
Non-ionic surfactant for mild, effective cleansing and foam/viscosity support in sulfate-free formulations.
Texture Enhancer Cleansing Agent Barrier Support Emulsifier
Sodium Benzoate GOOD
Functions as a preservative (antimicrobial), protecting water-containing formulations from yeast, mold, and bacterial spoilage. Its activity is pH-dependent and strongest in acidic systems (optimal below roughly pH 5), so it is used in low-pH products and frequently paired with potassium sorbate for broader, more robust preservation.
Preservative
Ethylhexylglycerin GOOD
A multifunctional additive that boosts preservative efficacy, provides deodorant activity, and conditions skin with a light, non-greasy feel.
Preservative Microbiome Balance Agent

Potassium Sorbate GOOD
Functions as a preservative (antimicrobial), protecting water-containing formulations primarily against yeasts and molds, with weaker activity against bacteria. Its activity is pH-dependent and strongest in acidic systems (effective below roughly pH 6, optimal near pH 4.4), so it is used in low-pH products and is commonly paired with a second preservative such as sodium benzoate for broad-spectrum coverage.
Preservative
Sodium Dehydroacetate NOT RATED
1,2-Hexanediol GOOD
A multifunctional glycol used as a humectant and preservative booster with mild antimicrobial activity.
Hydrator Preservative
