Judging from the ingredient list, "Peter Thomas Roth - Water Drench Hyaluronic Acid Moisturizer" works well for improving skin hydration To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Peter Thomas Roth - Water Drench Hyaluronic Acid Moisturizer ticks this box. Humectants in this product (glycerin, saccharide isomerate, saccharomyces/copper ferment, saccharomyces/iron ferment and saccharomyces/magnesium ferment) 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 (caprooyl phytosphingosine, ceramide eop, ceramide np, ceramide ns and cholesterol) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

As a plus, this moisturizer also contains ceramides (caprooyl phytosphingosine 0.30% - 0.60%, ceramide np 0.60% - 0.90%, ceramide ap 0.65% - 1.00%, caprooyl sphingosine 0.25% - 0.50%, ceramide ns 0.50% - 0.80%, ceramide eos 0.95% - 1.15% and ceramide eop 1.20% - 1.50%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.

Water Drench Hyaluronic Acid Moisturizer

Source: 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, saccharide isomerate.

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: dimethicone, cholesterol.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: caprooyl phytosphingosine, caprooyl sphingosine, ceramide ap, ceramide eop, ceramide eos, ceramide np, ceramide ns
