Review

Results you may expect from using Westman Atelier Skin Activator Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Westman Atelier Skin Activator Serum:

  • Moderate moisturizing. It has a moisturizing rating of 5.4 out of 10.
  • Considerable anti-wrinkle efficacy: Westman Atelier Skin Activator Serum has an anti-wrinkle rating of 4.5 out of 10, indicating a moderate ability to reduce wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: Westman Atelier Skin Activator Serum has a moisturizing rating of 5.4 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.8 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%), Pentylene Glycol (est. ≈4.0%) and Niacinamide (est. ≈3.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Westman Atelier Skin Activator Serum has a moderate anti-wrinkle rating of 4.5 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈3.0%),
 one of the most effective and well-researched anti-wrinkle ingredients.
 
Among others, Westman Atelier Skin Activator Serum also contains some ingredients marketed as effective in reducing wrinkles, specifically Lactobacillus Ferment, Camellia Sinensis Leaf Extract, Adenosine, Ascorbyl Glucoside, Beta-Glucan, Gluconolactone, and Swertia Chirata 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 contribute to 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 additional anti-wrinkle efficacy through its moisturizing action.
 

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

Antioxidant benefits

We estimate that Westman Atelier Skin Activator Serum is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈3.0%).

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. %70
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.
Glycerin
Est. %6
Function
Origin
Glycerin

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

Pentylene Glycol
Est. %4
Function
Origin

A naturally or synthetically derived preservative that exhibits effective antifungal and antibacterial traits. It also acts as a booster for more traditional preservatives. Pentylene glycol can also serve as a moisturizing humectant and solvent.

Niacinamide
Est. %3
Function
Origin
Niacinamide

Also known as vitamin B3, this ingredient is a true superstar with confirmed moisturizing, anti-acne, hyperpigmentation, and antioxidant benefits. Two studies confirm its significant anti-wrinkle efficacy.

Butylene Glycol
Est. %2
Function
Origin
Butylene GlycolA 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.
Morinda Citrifolia Fruit Juice
Est. %1.5
Function
Origin
Morinda Citrifolia Fruit Juice
Caprylic/Capric Triglyceride
Est. %1.3
Function
Origin
Caprylic/Capric TriglycerideA natural occlusive moisturizing and emollient ingredient, it is a blend of glycerin and two fatty acids, caprylic and capric acid. It creates an oil-based protective layer on the skin, thereby preventing water loss.
Propanediol
Est. %1
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.
Lactobacillus Ferment
Est. %0.3
Function
Origin
Lactobacillus FermentA biotechnological product – a mixture of metabolic products of Lactobacillus culture. Some Lactobacillus forms have been reported to have anti-wrinkle and barrier repairing effects, as well as able to improve skin hydration, elasticity, and gloss.
Glyceryl Caprylate
Est. %0.3
Function
Origin

Function
Origin
Sorbitan StearateA vegetable-derived ingredient most commonly used as an emulsifier to stabilize water and oil mixtures.
Sclerotium Gum
Est. %0.3
Function
Origin

Lecithin
Est. %0.3
Function
Origin
LecithinA humectant, emollient, and emulsifier best suited for water-in-oil emulsions. Lecithin can come from sunflowers, soy, and eggs. The downside to lecithin is that it causes an extra burden on the formula’s preservative because it is nutritious.
Pullulan
Est. %0.3
Function
Origin
Pullulan
Saccharomyces Cerevisiae Extract
Est. %0.3
Function
Origin
Saccharomyces Cerevisiae ExtractA fungi ingredient made from baker's yeast. It is moisturizing and contains various beneficial compounds that support skin health. Among these is beta-glucan, the praised wound healing polysaccharide.

Est. %0.3
Function
Origin
Opuntia Ficus-Indica Fruit Extract
Camellia Sinensis Leaf Extract
Est. %0.3
Function
Origin

Arginine
Est. %0.3
Function
Origin
ArginineA humectant amino acid used to attract water to the skin’s surface. It is a part of the skin's Natural Moisturizing Factor, a mixture of various compounds that keeps the skin’s surface well hydrated. Arginine can also be used as a pH adjuster.
Adenosine
Est. %0.3
Function
Origin
Adenosine

A key molecule responsible for energy transportation, signaling, and enzyme activity. Adenosine is a popular anti-wrinkle ingredient, however, the key study about its anti-wrinkle efficacy (1) does not meet CreamScan Research Evaluation Standards as it is not double-blind.

Sodium Acetylated Hyaluronate
Est. %0.3
Function
Origin
Sodium Acetylated HyaluronateA chemically modified version of hyaluronic acid. It is more stable and less sticky than regular HA, while still providing the same humectant moisturizing properties (according to the manufacturer). There have been no clinical studies to confirm this.
Sodium Hyaluronate
Est. %0.3
Function
Origin
Sodium Hyaluronate

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
PhenoxyethanolThe 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.
Cystoseira Tamariscifolia Extract

Function
Origin
Cystoseira Tamariscifolia Extract
Sodium Hyaluronate Crosspolymer
Est. %0.3
Function

Glutamine
Est. %0.3
Function
Origin
GlutamineA humectant moisturizing amino acid that, aside from attracting water to the skin’s surface, can also soothe allergic itching and reduce the signs of inflammation.
Ascorbyl Glucoside
Est. %0.3
Function
Origin
Ascorbyl GlucosideA derivative of vitamin C. It is more stable and less irritating than ascorbic acid. There are unfortunately no clinical studies on ascorbyl glucoside’s anti-pigment or anti-acne efficacy alone.
Maltodextrin
Est. %0.3
Function
Origin
MaltodextrinA formula helper manufactured from starch. It has a sweet flavor and is often used in rinse-off products to support their foaming structure. Maltodextrin is also used to stabilize emulsions and to absorb and bind other ingredients in the formula.
Olive Glycerides
Est. %0.3
Function
Origin
Olive Glycerides
Caprylyl Glycol
Est. %0.3
Function
Origin
Caprylyl GlycolAn emollient that improves product spreadability and offers a silky feel on the skin. It also acts as a preservative booster that improves the efficacy of other preservatives. According to the manufacturer, it is also a humectant moisturizer.

Myristyl Alcohol
Est. %0.3
Function
Origin
Myristyl AlcoholA naturally derived fatty alcohol that thickens and stabilizes emulsions.
Ceramide NP
Est. %0.3
Function
Origin
