Things to Be Aware Of: Peter Thomas Roth Skin to Die For Darkness-Reducing Under-Eye Treatment Primer

 
CreamScan identified a few things to consider before adding Peter Thomas Roth Skin to Die For Darkness-Reducing Under-Eye Treatment Primer to your skincare routine:
 

⚠️ Best for Very Dry Skin - May Be Too Thick for Other Skin Types

With exceptional occlusivity, this product is optimal for moisturizing dry and very dry skin but may be too thick for other skin types, including normal, and especially combination and oily skin.

If you have oily, combination, or normal skin and are considering purchasing this product for the first time, it might be a good idea to try a sample before buying.

⚠️ Needs to Be Paired with Extra Humectants for Optimal Moisturizing Efficacy

An ideal moisturizer for any skin type should balance the right level of occlusivity (depending on skin type) with a significant amount of humectants, while Peter Thomas Roth Skin to Die For Darkness-Reducing Under-Eye Treatment Primer contains a low level of humectants.

People with dry skin would definitely benefit from adding more humectants to their moisturizing routine beyond what this product offers. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Peter Thomas Roth Skin to Die For Darkness-Reducing Under-Eye Treatment Primer is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains some ingredients often marketed as effective in reducing wrinkles, specifically Palmitoyl Tetrapeptide-7, Palmitoyl Oligopeptide, Coffea Arabica (Coffee) Seed Extract, and Caffeine. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. 

While this does not categorically rule out the possibility that these ingredients may reduce wrinkles, their efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

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, can deliver some anti-wrinkle effects through its moisturizing action.

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

Est. %40
Function
Origin
DimethiconeThe 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.
Isododecane
Est. %22
Function
Origin
IsododecaneAn emollient derived from petroleum with high spreadability. It is often used as a replacement for oils and silicones because it leaves no residue behind on the skin. When a product is labeled as “oil-free” it may contain isododecane instead of heavier oils.
Stearoxymethicone/Dimethicone Copolymer
Est. %11
Function
Origin
Stearoxymethicone/Dimethicone Copolymer
Isononyl Isononanoate
Est. %6
Function
Origin

Polymethylsilsesquioxane
Est. %4
Function
Origin

Silica
Est. %3
Function
Origin
SilicaA widely used cosmetic ingredient with the same chemical composition as the sand found on beaches. A common function of silica is its ability to control viscosity. In certain chemical forms, it can effectively thicken cream-style products.
Polysilicone-11

Water
Est. %1.5
Function
Origin
WaterThe 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.
Methyl Methacrylate Crosspolymer
Est. %1
Function
Origin
Methyl Methacrylate CrosspolymerA synthetic ingredient that is used for bulking, film-forming, and controlling viscosity. It can absorb large amounts of water and oil and creates a network for other ingredients to live in.
Mica
Est. %0.3
Function
Origin
MicaA mineral powder made up of silicates with several functions (the main one being as a colorant). It has a shimmery appearance, making it highly desirable in certain cosmetic products. Mica also helps the product to apply more smoothly.
Palmitoyl Tetrapeptide-7
Est. %0.3
Function
Origin
Palmitoyl Tetrapeptide-7

A synthetic peptide that mimics the activity of immunoglobulin G and signals to the skin to stop the inflammation. It has been shown in studies to reduce wrinkles and enhance collagen content.

Palmitoyl Oligopeptide
Est. %0.3
Function
Origin
Palmitoyl Oligopeptide

This is an old INCI name that can refer to several other peptides. They are all short fragments of collagen or elastin and function as signal molecules, telling the skin to repair and restructure the dermis, resulting in anti-wrinkle activity.

Hydrolyzed Collagen
Est. %0.3
Function
Origin
Hydrolyzed Collagen

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.

Biotin
Est. %0.3
Function
Origin
BiotinBiotin is an important nutrient that can cause weak hair and nails if deficient. Unfortunately, while biotin supplements have promising studies, topical biotin in creams and serums doesn’t have a large body of evidence to support its use.
Chrysin
Est. %0.3
Function
Origin
ChrysinChrysin is thought to help promote blood circulation in blends with other ingredients and allegedly can help to reduce the appearance of dark under-eye circles. However, no official studies have been done to confirm this.
Arnica Montana Flower Extract
Est. %0.3
Function
Origin
Arnica Montana Flower ExtractAn extract derived from the flower heads of the mountain arnica plant. This plant is used as herbal medicine to treat wounds, bruises, and inflammation. In skincare, however, it is mostly added for fragrance purposes due to its pleasant pine and sage odor.
Coffea Arabica (Coffee) Seed Extract
Est. %0.3
Function
Origin
Coffea Arabica (Coffee) Seed ExtractAn antioxidant and emollient extract derived from coffee beans. It has been proven to improve collagen and elastin production in the skin. A small clinical study tested the anti-aging effects of coffee berry extract, and the results were very promising.
Caffeine
Est. %0.3
Function
