Key Benefits of Peter Thomas Roth Water Drench Hyaluronic Cloud Serum

 
These are the key benefits you can expect from using Peter Thomas Roth Water Drench Hyaluronic Cloud Serum:
 

Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, Peter Thomas Roth Water Drench Hyaluronic Cloud Serum is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Saccharide Isomerate (est. ≈3.0%), Sodium Hyaluronate (est. ≈2.5%) and Sodium PCA (est. ≈2.4%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

Tip: Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

A Humectant Boost for Any Skincare Routine

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Rich in Skin-Protecting Antioxidants

We estimate that Peter Thomas Roth Water Drench Hyaluronic Cloud Serum is rich (> 3%) in antioxidants, specifically Sodium Hyaluronate (est. ≈2.5%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Peter Thomas Roth Water Drench Hyaluronic Cloud Serum

 
CreamScan AI identified a few things to consider before adding Peter Thomas Roth Water Drench Hyaluronic Cloud Serum to your skincare routine:
 

If It’s Your Only Moisturizer, It Needs to Be Paired with Some Occlusives

While humectants are highly effective at attracting water to the skin, studies (J. N. Kraft, C. W. Lynde) suggest they may not be efficient when used alone.

One major drawback of purely humectant moisturization is that the water attracted by humectants to the upper layers of the skin can evaporate completely into the environment through transepidermal water loss (TEWL). Adding occlusive ingredients helps seal this moisture into the skin and prevent further water loss.

If you’re using Peter Thomas Roth Water Drench Hyaluronic Cloud Serum as your only moisturizer, consider pairing it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones. These work alongside humectants to create a protective barrier, locking in hydration and ensuring longer-lasting moisturization. The amount of occlusive needed depends on your skin type - the drier the skin, the more occlusives it requires.

If this product is used not as a standalone moisturizer but as part of your skincare routine, such as a toner or serum, it should be applied before your main moisturizer (unless it's a sunscreen), which will provide the necessary occlusivity on top of it.

Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Peter Thomas Roth Water Drench Hyaluronic Cloud Serum is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains some ingredients often marketed as effective in reducing wrinkles, specifically Saccharomyces/Copper Ferment, Saccharomyces/Zinc Ferment, and Olea Europaea (Olive) Leaf Extract. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. 

While this does not categorically exclude the possibility that these ingredients may reduce wrinkles, their efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were accessible to the CreamScan team at the time of publication.

Therefore, these ingredients do not generate the anti-wrinkle rating.

Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.
