What the product description says
“Pocket-Sized Derma Protective Cream”
From product name

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: glycerin, sorbitol.

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: paraffinum liquidum, cetyl alcohol.

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

Product summary

"Prep - Pocket-Sized Derma Protective Cream" is a well-rounded moisturizing product. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Prep - Pocket-Sized Derma Protective Cream ticks this box. Humectants in this product (glycerin and sorbitol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (paraffinum liquidum, cetyl alcohol and stearic acid) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
