Does facetheory PolyPep Collagen Boosting Serum S8 work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using facetheory PolyPep Collagen Boosting Serum S8:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.0 out of 10.

Lightweight moisturizer ideal for oily skin and a humectant boost for any skincare routine

According to CreamScan analysis, facetheory PolyPep Collagen Boosting Serum S8 is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Propanediol (est. ≈6.0%), Gluconolactone (est. ≈4.0%) and Urea (est. ≈3.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

Tip: Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

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

Questionable anti-wrinkle efficacy

According to CreamScan analysis, facetheory PolyPep Collagen Boosting Serum S8 has a zero anti-wrinkle rating.

It contains some ingredients often marketed as effective in reducing wrinkles, specifically Gluconolactone, Caprooyl Tetrapeptide-3, and Camellia Sinensis Leaf Extract. 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, can deliver some anti-wrinkle effects through its moisturizing action.

Ingredients explained

Water
Est. %80
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.
Propanediol
Est. %6
Function
Origin
PropanediolAn 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.
Gluconolactone
Est. %4
Function
Origin
GluconolactoneA PHA derived from glucose. It has exfoliating and humectant properties and acts as a penetration enhancer for other ingredients. It has also been shown to assist in the treatment of acne and the prevention of photoaging.
Urea
Est. %3
Function
Origin
UreaUrea can be found in urine, skin, and other tissues as a degradation product of proteins. In concentrations below 5%, urea is humectant moisturizing. At concentrations above 10% it is keratolytic, that helps to break away old, flaking, and cracked skin.
Glycerin
Est. %2
Function
Origin
Glycerin

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

Chamomilla Recutita (Matricaria) Flower Extract
Est. %1.5
Function

Dextran
Est. %1.3
Function
Origin
DextranA naturally derived sucrose metabolite that thickens water and bulks emulsions.
Caprooyl Tetrapeptide-3
Est. %0.3
Function
Origin
Caprooyl Tetrapeptide-3

A synthetically made peptide that was designed to emulate the skin growth factor. It is said to boost the production of the skin's structural elements and the dermo-epidermal junction, although this has not been independently tested.

Sodium Phytate
Est. %0.3
Function
Origin
Sodium PhytateSodium phytate is a chelating agent that serves to remove heavy metal ions from water. Removing metal ions helps other ingredients, such as antioxidants and preservatives, to perform better and keep products from separating.
Camellia Sinensis Leaf Extract
Est. %0.3
Function
Origin
Camellia Sinensis Leaf Extract

An antioxidant green tea extract. In the deeper layers, it slows down the destruction of collagen, elastin, and hyaluronic acid – thus delaying the signs of aging. It also acts as an anti-acne, soothing, moisturizing, and emollient ingredient.

Centella Asiatica Flower/Leaf/Stem Extract
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.

Citric Acid
Est. %0.3
Function
Origin
Citric AcidA 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.
Potassium Sorbate
Est. %0.3
Function
Origin
Potassium SorbateA 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.
