Key Benefits of La Roche-Posay Hydraphase Intense Serum with Hyaluronic Acid

 
These are the key benefits you can expect from using La Roche-Posay Hydraphase Intense Serum with Hyaluronic Acid:
 

🔵 Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, La Roche-Posay Hydraphase Intense Serum with Hyaluronic Acid is quite moisturizing, with a moisturizing rating of 5.3 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.6 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Butylene Glycol (est. ≈6.0%), Glycerin (est. ≈3.0%) and Bis-PEG-18 Methyl Ether Dimethyl Silane (est. ≈2.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients.

It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

💧 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.

Things to Be Aware Of: La Roche-Posay Hydraphase Intense Serum with Hyaluronic Acid

 
CreamScan AI identified a few things to consider before adding La Roche-Posay Hydraphase Intense Serum with Hyaluronic Acid to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing La Roche-Posay Hydraphase Intense Serum with Hyaluronic Acid is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Ascorbyl Glucoside, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Ascorbyl Glucoside provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that Ascorbyl Glucoside may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

Therefore, this ingredient does 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.

Ingredients explained

Water
Est. %80
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.
Butylene Glycol
Est. %6
Function
Origin
Butylene Glycol

A clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.

Alcohol Denat.
Est. %4
Function
Origin
Alcohol Denat.

Denatured alcohol is ethanol that contains additives that make it unsafe to consume. It is mainly used as a solvent and an antimicrobial agent. A major drawback to alcohol denat. is that it dries out the skin.

Phenoxyethanol
Est. %0.3
Function
Origin
PhenoxyethanolThe most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
