Key Benefits of Yves Saint Laurent All Hours Full Coverage Matte Foundation SPF 20

 
These are the key benefits you can expect from using Yves Saint Laurent All Hours Full Coverage Matte Foundation SPF 20:
 

🔵 Lightweight Purely Humectant Moisturizer Well-Suited for Oily Skin

According to CreamScan analysis, Yves Saint Laurent All Hours Full Coverage Matte Foundation SPF 20 is lightly moisturizing, with a moisturizing rating of 3.2 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a high humectancy of 6.3 out of 10, primarily due to the high content of Butylene Glycol (est. ≈4.0%) and Glycerin (est. ≈2.0%).

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

📌 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 Enhancement for Any Skincare Routine

But it’s not limited to oily skin - such a humectant enhancement 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.

☀️☀️ Moderate Sun Protection for Short Outdoor Activities

With an SPF of 20, Yves Saint Laurent All Hours Full Coverage Matte Foundation SPF 20 provides moderate sun protection. It is suitable for individuals with medium to darker skin tones who are less prone to sunburn and those engaging in short outdoor activities such as walking or brief errands, as well as cloudy days when UV exposure is less intense.

It helps protect against UVB rays, which are primarily responsible for sunburn and increase the risk of skin cancer by damaging the outer layers of the skin. When labeled as broad-spectrum, it also defends against UVA rays, which penetrate deeper into the skin and cause premature aging, hyperpigmentation, and long-term cellular damage.

📌 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.

However, if you spend a substantial amount of time outdoors, it is better to use a broad spectrum sunscreen with an SPF 30 or higher.

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

Things to Be Aware Of: Yves Saint Laurent All Hours Full Coverage Matte Foundation SPF 20

 
CreamScan identified a few things to consider before adding Yves Saint Laurent All Hours Full Coverage Matte Foundation SPF 20 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 Yves Saint Laurent All Hours Full Coverage Matte Foundation SPF 20 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.

Pros & Cons of Yves Saint Laurent All Hours Full Coverage Matte Foundation SPF 20

Ingredients explained

Cyclohexasiloxane
Est. %45
Function
Origin
CyclohexasiloxaneA clear silicone fluid with very low viscosity that is commonly used as a solvent and emollient. It has excellent spreadability, rubs in quickly, and leaves a silky smooth after-feel on the skin.
Alcohol Denat.
Est. %22
Function
Origin

Est. %6
Function
Origin
Acrylates/Polytrimethylsiloxymethacrylate Copolymer
Butylene Glycol
Est. %4
Function
Origin

Butyrospermum Parkii (Shea) Seedcake Extract
Est. %0.3
Function
Origin
Butyrospermum Parkii (Shea) Seedcake Extract
Hydroxyethylcellulose
Est. %0.3
Function
