Key Benefits of Marc Jacobs Beauty Shameless Youthful-Look 24H Foundation SPF 25

 
These are the key benefits you can expect from using Marc Jacobs Beauty Shameless Youthful-Look 24H Foundation SPF 25:
 

🔵 Lightweight Moisturizer Suitable for Combination and Oily Skin

According to CreamScan analysis, Marc Jacobs Beauty Shameless Youthful-Look 24H Foundation SPF 25 is lightly moisturizing, with a moisturizing rating of 3.4 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 2.1 out of 10 and a moderate humectancy of 4.8 out of 10, primarily due to the high content of Sorbitol (est. ≈2.0%).

This type of moisturizer is suitable for people with oily and combination skin who want essential hydration in a relatively lightweight, non-greasy formula. It combines a substantial amount of humectants with a limited amount of occlusive ingredients to enhance moisturizing efficacy without feeling too heavy.

💧 A Humectant Add-on for Any Skincare Routine

But it’s not limited to combination and oily skin - since it contains a moderate amount of humectants, such a humectant add-on will 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.

☀️☀️ Moderate Sun Protection for Short Outdoor Activities

With an SPF of 25, Marc Jacobs Beauty Shameless Youthful-Look 24H Foundation SPF 25 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 AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.
