Overview

How moisturizing is this?

Quite moisturizing. Dr. Barbara Sturm Clarifying Serum has a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive?

Purely humectant. It has a very high Humectancy of 9.9 out of 10 and zero Occlusivity (we didn't find any occlusives on the ingredient list).
Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

What else is good about it?

 Dr. Barbara Sturm Clarifying Serum is rich in antioxidants. One of the many benefits of antioxidant ingredients is that they are believed to reduce the oxidative stress caused by free radicals, thus preventing accelerated skin aging.

Ingredients explained

Water
Est. %80
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.
Propanediol
Est. %6
Function
Origin
An 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/Portulaca Oleracea Ferment Extract
Est. %4
Function
Origin
Product of fermentation by Lactobacillus bacteria of purslane extract, which is rich in antioxidant flavonoids, terpenes, and carotenoids.
Zinc PCA
Est. %3
Function
Origin
A two-part ingredient: Zinc helps to control sebum and bacteria in acne-prone skin, while skin-identical PCA is a moisturizing humectant. Zinc PCA may even boost collagen production and so is researched as a potential anti-wrinkle ingredient.
Phenoxyethanol
Est. %1
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.
Xanthan Gum
Est. %1
Function
Origin
A natural multi-functional ingredient that originates from fermented sugars. Xanthan gum acts as a viscosity-building agent to thicken skincare products. It is also an excellent stabilizer and works well to hold other ingredients together.
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.
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.
Ethylhexylglycerin
Est. %0.3
Function
Origin
A preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.
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.
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.
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.
