Overview

How moisturizing is this?

Quite moisturizing. Dr. Barbara Sturm Hyaluronic Serum has a moisturizing rating of 4.0 out of 10.

Is it more humectant or occlusive?

Purely humectant. It has a very high Humectancy of 8.0 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 Hyaluronic 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. %85
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.
Butylene Glycol
Est. %6
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.
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.
Ethylhexylglycerin
Est. %1
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.
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.
Sodium Hyaluronate
Est. %1
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.
Potassium Sorbate
Est. %0.3
Function
Origin
A 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.
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.
