Dr. Barbara Sturm Clarifying Mask

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: arginine, hyaluronic acid.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: arginine, simmondsia chinensis seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

This product contains ingredients (zinc pca) that could help reduce blemishes and clogged pores in theory, but there is not enough evidence that they actually work.

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.These ingredients - hyaluronic acid, magnesium aluminum silicate, zinc pca - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

This product contains ingredients (lactobacillus/portulaca oleracea ferment extract) that could help reduce hyperpigmentation (for example, post-acne marks or age spots) in theory, but there is not enough evidence that they actually work.
