How moisturizing is it?

Lightly moisturizing: Peter Thomas Roth Potent-C Vitamin C Targeted Spot Brightener has a moisturizing rating of 2.2 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 0.2 out of 10 and a moderate humectancy of 4.2 out of 10, primarily due to the high content of Butylene Glycol (est. ≈3.3%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Peter Thomas Roth Potent-C Vitamin C Targeted Spot Brightener has a zero anti-wrinkle rating.

It contains Tetrahexyldecyl Ascorbate, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Tetrahexyldecyl Ascorbate provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does 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.

Antioxidant benefits

We estimate that Peter Thomas Roth Potent-C Vitamin C Targeted Spot Brightener is rich (> 3%) in antioxidants, specifically Tetrahexyldecyl Ascorbate (est. ≈10.0%), Tocopheryl Acetate (est. ≈3.0%) and Ferulic Acid (est. ≈2.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

Ingredients explained

Water
Est. %60
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.
Tetrahexyldecyl Ascorbate
Est. %10
Function
Origin
A lipid-soluble form of vitamin C that is more stable and less irritating than ascorbic acid. According to a recent clinical study, THDA has all the capabilities of regular vitamin C, including anti-wrinkle and anti-pigment activity.

Butylene Glycol
Est. %3.3
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.
Magnesium Aluminum Silicate
Est. %3.2
Function
Origin
A naturally occurring clay that is hygroscopic, which means that it easily absorbs water. This ingredient is thus commonly used as an absorbent and emulsion stabilizer. It also modifies slip by improving the spreadability of the products it is used in.
Cetearyl Alcohol
Est. %3.1
Function
Origin
A blend of cetyl alcohol and stearyl alcohol, the fatty alcohols that are derived from palm oil. It helps to create emulsions that give off a soft and silky emollient feel and also increase product thickness.
Tocopheryl Acetate
Est. %3
Function
Origin
An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.
Glyceryl Stearate
Est. %2.2
Function
Origin
An emollient and emulsifier typically derived from vegetable sources through a chemical reaction with glycerin. It provides stability, texture, and consistency to formulations. Its main function is to allow oil and water to mix.
PEG-100 Stearate
Est. %2.1
Function
Origin
This surfactant is more specifically classified as an emulsifier that produces oil-in-water emulsions. PEG-100 stearate can also be used as a cleansing agent.
Ferulic Acid
Est. %2
Function
Origin
A plant-based phenolic acid with powerful and scientifically proven antioxidant properties. It enhances the effects of vitamins C and E, as well as the UV protective effects of sunscreens.
Isopropyl Palmitate
Est. %0.3
Function
Origin
An emollient ester of palmitic acid and isopropanol that gives the skin a smooth, soft, dry, non-oily after-feel. Isopropyl palmitate is listed as a common comedogenic ingredient by acne.org.
Glycerin
Est. %0.3
Function
Origin

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

Ceteareth-20
Est. %0.3
Function
Origin
A fatty alcohol emulsifier that helps to mix oil and water together, best for oil-in-water emulsions. It is also a cleansing agent. When combined with cetearyl alcohol, ceteareth-20 forms a mix that, according to acne.org, can be comedogenic.
Dimethicone
Est. %0.3
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.
Allantoin
Est. %0.3
Function
Origin
A fluffy, white powder that acts as a humectant due to its water-loving chemistry and as an exfoliant that helps to remove dead skin cells. It has also been shown to be very soothing to irritated and inflamed skin.
Aloe Barbadensis Leaf Juice
Est. %0.3
Function
Origin
A gelatinous juice from Aloe vera leaves that acts as a powerful humectant, emollient, and antioxidant. It contains enzymes, amino acids, vitamins, and minerals that soothe irritated skin and have wound-healing and anti-inflammatory properties.
Angelica Acutiloba Root Extract
Est. %0.3
