How moisturizing is it?

Intensely moisturizing: Peter Thomas Roth FIRMxВ Collagen Moisturizer has a moisturizing rating of 8.2 out of 10.

Is it more humectant or occlusive? Rather 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. ≈6.0%), and a high occlusivity of 6.3 out of 10, mainly due to the significant content of Dimethicone (est. ≈11.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Peter Thomas Roth FIRMxВ Collagen Moisturizer 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.

Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, could deliver some anti-wrinkle effects through its moisturizing action.

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.
Dimethicone
Est. %11
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.
Butylene Glycol
Est. %6
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.
Polysilicone-11
Est. %4
Function
Origin
A synthetic rubber-like substance of the silicone family that has no color or distinct scent. These are large molecules that cannot penetrate the skin but instead create a thin silky film on the skin's surface.
Glycerin
Est. %3
Function
Origin

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

Acrylamide/Sodium Acryloyldimethyltaurate Copolymer
Est. %2
Function
Origin
A synthetic ingredient that forms a gel when mixed with water. It can thus thicken and stabilize a product.
Caffeine
Est. %1.5
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).
Squalane
Est. %1
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.
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.
Hydroxystearic Acid
Est. %0.3
Function
Origin
A strongly emollient and occlusive saturated fatty acid isolated from castor oil.
Hydroxyproline
Est. %0.3
Function
Origin
An amino acid that may promote collagen synthesis.
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.
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.
Phenoxyethanol
Est. %0.3
Function
Origin
The most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Isohexadecane
Est. %0.3
Function
Origin
A clear, colorless liquid that is commonly used as an emollient. It is made up of pure hydrocarbons and leaves a dry feeling on the skin upon application. It also increases the spreadability of a product.
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.
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.
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.
Polysorbate 80
Est. %0.3
Function
Origin
A non-ionic surfactant, which means that it contains no chemical charges. It can be used as a mild cleansing agent in skin cleansing products but is more commonly used for its emulsifying abilities.
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.
Polysorbate 20
Est. %0.3
Function
Origin
A viscous, amber-colored liquid that functions as a solubilizer to disperse small amounts of oil into a large water phase. Polysorbate 20 is frequently used to solubilize fragrance oils into water-based emulsions.
Decyl Glucoside
Est. %0.3
Function
Origin
A surfactant that can function as both a cleansing agent and emulsifier. As a cleansing agent, it is very mild on the skin. As an emulsifier, decyl glucoside will produce oil-in-water emulsions. It is naturally derived from vegetable oils and starch.
Sorbitan Oleate
Est. %0.3
Function
Origin
A vegetable-based ingredient that stabilizes mixtures of oil and water. Sorbitan oleate serves primarily as an emulsifier that produces water-in-oil emulsions.
Sodium Hydroxide
Est. %0.3
Function
Origin
An ingredient that is able to bring the pH of a product up, thereby making it less harsh on the skin.
Disodium EDTA
Est. %0.3
Function
Origin
A synthetic chelator that helps to maintain the look and smell of a product by 'locking up' troublesome metal ions.
Caprylyl Glycol
Est. %0.3
Function

Hexylene Glycol
Est. %0.3
Function
Origin
A multifunctional ingredient that is best known for its use as a solvent. It can dissolve both water-based ingredients and oils. For this reason, it can also function as an emulsifier, allowing oil and water ingredients to mix and remain stable.
Potassium Sorbate
Est. %0.3
Function
Origin
A preservative widely used in food and personal care products, available from natural sources or synthetically produced. Potassium sorbate works by inhibiting the growth of yeasts, molds, and some bacteria.
Sodium Benzoate
Est. %0.3
