Does Peter Thomas Roth Water DrenchВ Hyaluronic Hydrating Moisturizer SPF 45 work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Peter Thomas Roth Water DrenchВ Hyaluronic Hydrating Moisturizer SPF 45:

  • Light moisturizing. It has a moisturizing rating of 3.0 out of 10.
  • High sun protection for extended outdoor activities and exposure.

Basic moisturizer for oily skin

According to CreamScan analysis, Peter Thomas Roth Water DrenchВ Hyaluronic Hydrating Moisturizer SPF 45 is lightly moisturizing, with a moisturizing rating of 3.0 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 1.3 out of 10 and a moderate humectancy of 4.7 out of 10, primarily due to the high content of Glycerin (est. ≈2.0%).

This product, when used alone as a moisturizer, can provide light humectant hydration in a fast-absorbing formula with a minimal amount of occlusive ingredients. This could work for people with oily skin who need a basic level of hydration.

Since it contains a moderate amount of humectants, it can also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer.

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

Questionable anti-wrinkle efficacy

According to CreamScan analysis, Peter Thomas Roth Water DrenchВ Hyaluronic Hydrating Moisturizer SPF 45 has a zero anti-wrinkle rating.

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

High sun protection for extended outdoor activities and exposure

With an SPF of 45, Peter Thomas Roth Water DrenchВ Hyaluronic Hydrating Moisturizer SPF 45 provides high sun protection, making it ideal for prolonged outdoor activities such as hiking, gardening, sports, or spending time at the beach.

This level of SPF blocks up to 98% of UVB rays, significantly reducing the risk of sunburn. When formulated as broad-spectrum, it also protects against UVA rays, which penetrate deeper into the skin and contribute to premature aging, hyperpigmentation, and long-term damage.

This level of SPF is recommended for most skin types, including those with moderate sun sensitivity. For individuals with fair or very sensitive skin, or under intense sun exposure, a higher SPF of 50+ is advised.

For optimal protection, choose products labeled broad-spectrum to ensure defense against both UVA rays, which contribute to skin aging and pigmentation, and UVB rays that cause sunburn.

It's important to apply sunscreen generously and reapply every two hours or after swimming or sweating to maintain effectiveness.

Ingredients explained

Water
Est. %55
Function
Origin
WaterThe 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.
Octocrylene
Est. %10
Function
Origin
OctocryleneA synthetic compound that protects skin against harmful ultraviolet light.
Homosalate
Est. %5
Function
Origin
HomosalateA synthetic chemical UV filter that protects against harmful UVB radiation.
Octisalate
Est. %5

Avobenzone
Est. %3
Function
Origin
AvobenzoneA popular sunscreen that protects against UVA rays, which cause premature aging and skin cancer. Avobenzone degrades after about 30 minutes of sun exposure and becomes ineffective. It is therefore often paired with UV-filter stabilizers such as octocrylene.
Polymethylsilsesquioxane
Est. %2.5
Function
Origin
