Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Collagen (est. ≈40.0%) and Butylene Glycol (est. ≈11.0%), and a moderate occlusivity of 4.5 out of 10, mainly due to the high content of Dimethicone (est. ≈6.0%) and Squalane (est. ≈2.0%).

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Anti-wrinkle efficacy

According to CreamScan analysis, Peter Thomas Roth FIRMx Collagen Eye Cream has a zero anti-wrinkle rating.

It contains some ingredients marketed as effective in reducing wrinkles, specifically Caffeine, Palmitoyl Tripeptide-5, and Palmitoyl Dipeptide-5 Diaminobutyroyl Hydroxythreonine. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do not generate the anti-wrinkle rating.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Ingredients explained

Collagen
Est. %40
Function
Origin
A protein that builds all human tissues, especially skin and joints. It is used as a moisturizing humectant ingredient in skincare.
Water
Est. %22
Function
Origin
The most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Butylene Glycol
Est. %11
Function
Origin
A clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.
Dimethicone
Est. %6
Function
Origin
The most common silicone in skincare. It forms a silky, smooth film on the skin’s surface and can help to prevent water loss. It also aids in wound healing and can treat and soften scars. Dimethicone is considered to be very safe for use.
Dimethicone/PEG-10/15 Crosspolymer
Est. %3
Function
Origin
A self-emulsifying surfactant, which means that it can help facilitate the formation of water-in-silicone emulsions. This results in lightweight formulas with a soft finish. It can also act as a film-former and thickener.
Glycerin
Est. %2.9
Function
Origin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Squalane
Est. %2
Function
Origin
An occlusive moisturizing and emollient compound that forms part of the skin’s sebum. The main source of squalane had always been shark liver. Now, however, it is manufactured synthetically or derived from plant oils, such as olive and peanut oil.
Propanediol
Est. %1.5
Function
Origin
An excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer
Est. %1
Function
Origin
An emulsion stabilizer and thickener that helps to create a pleasant, satiny, and light formula texture. It works by forming a gel-like network within water or oil, which both stabilizes other ingredients and produces a thickening effect.
Caffeine
Est. %0.3
Function
Origin
An antioxidant compound that is obtained from coffee and tea leaves. It increases the microcirculation of blood in the skin and is claimed to be able to reduce the appearance of orange peel skin (although the research is lacking).
Hydrolyzed Collagen
Est. %0.3
Function
Origin
A humectant, film-forming, and emollient mixture of various proteins and peptides that were created by cutting the huge molecules of normal collagen into smaller pieces for better absorption. It also has some antioxidant properties.
Soluble Collagen
Est. %0.3
Function
Origin
A protein obtained from farm or marine animals. Collagen molecules are too big to penetrate the skin so when they are applied via a skincare product they sit on top of the skin and act as humectant moisturizers.
Collagen Amino Acids
Est. %0.3
Function
Origin
A mixture of amino acids obtained by chopping up collagen molecules. It consists mainly of glycine, proline, alanine, and hydroxyproline. They all have humectant properties.
Hydroxyproline
Est. %0.3
Function
Origin
An amino acid that may promote collagen synthesis.
Hydroxystearic Acid
Est. %0.3
Function
Origin
A strongly emollient and occlusive saturated fatty acid isolated from castor oil.
Palmitoyl Tripeptide-5
Est. %0.3
Function
Origin
A small synthetic peptide that signals the skin to produce more collagen. It has been clinically tested and proven to reduce skin roughness and the appearance of wrinkles.
Palmitoyl Dipeptide-5 Diaminobutyroyl Hydroxythreonine
Est. %0.3
Function
Origin
A synthetically made peptide that was designed to target the dermo-epidermal junction, where it should stimulate the production of structural proteins. It has not been clinically tested yet.
rh-Oligopeptide-1
Est. %0.3
Function
Origin

Hyaluronic Acid
Est. %0.3
Function
Origin
A potent, skin-identical humectant moisturizing ingredient that is able to bind water 1000 times its own weight. The anti-aging benefits of hyaluronic acid are due to its ability to stimulate the synthesis of collagen in the skin.
Jasminum Sambac (Jasmine) Flower Extract
Est. %0.3
Function
Origin
Description is coming soon
Crataegus Monogyna Flower Extract
Est. %0.3
Function
Origin
An extract obtained from the flowers of the hawthorn bush. It has a high content of astringent and antioxidant tannins and flavonoids.
Sodium Hyaluronate
Est. %0.3
Function
Origin
A sodium salt of famous hyaluronic acid. A potent humectant that hydrates the skin, supports collagen function, and fills out small wrinkles. Sodium hyaluronate also offers soothing and antioxidant properties.
Colloidal Oatmeal
Est. %0.3
Function
Origin
An active ingredient produced by boiling finely milled oats. It contains wound healing beta-glucan and is a rich source of soothing and antioxidant avenanthramides, which are aimed at irritated skin.
Hydrogenated Lecithin
Est. %0.3
Function
Origin
A version of plain lecithin that has been saturated with hydrogen atoms. This ingredient can be derived from plants, like soy or sunflower, from egg yolks, or made synthetically. Its major function is to emulsify water and oils.
Tocopherol
Est. %0.3
Function
Origin
Simply another name for vitamin E. Tocopherol is a fantastic ingredient and especially beneficial for dry and inflamed skin. It has occlusive moisturizing, emollient, antioxidant, and photoprotective properties.
Leuconostoc/Radish Root Ferment Filtrate
Est. %0.3
Function
Origin
A biotechnological fermentation ingredient that is created by feeding radish root to Leuconostoc kimchii. It allegedly contains organic acids and a mixture of peptides known as bacteriocins – which have antimicrobial activity.
Tetradecyl Aminobutyroylvalylaminobutyric Urea Trifluoroacetate
Est. %0.3
Function
Origin
A small, peptide-like ingredient designed to improve skin firmness and hydration by stimulating the production of proteins and peptidoglycans in the skin.
Ammonium Acryloyldimethyltaurate/VP Copolymer
Est. %0.3
Function
Origin
A polymeric ingredient that creates lightweight and refreshing gel textures. It also works as a viscosity controlling agent.
Citric Acid
Est. %0.3
Function
Origin
A gently exfoliating AHA that helps to remove the top layer of dead skin cells. In comparison to other AHAs, citric acid has been shown to be one of the least effective. It is also very commonly used as a stabilizing and pH-controlling agent.
Sodium Citrate
Est. %0.3
Function
Origin
A salt of citric acid that has a salty and tart flavor and is used as a fragrance. It is mildly basic, meaning that its addition to a skincare product can adjust the pH upward.
Sorbic Acid
Est. %0.3
Function
Origin
An organic acid that can be naturally found in the berries of the Mountain ash, although it is manufactured synthetically for skincare purposes. It is used as a preservative and antimicrobial agent, protecting a skincare product from spoiling.
