Key Benefits of La Roche-Posay Effaclar H Iso-Biome Moisturiser

 
These are the key benefits you can expect from using La Roche-Posay Effaclar H Iso-Biome Moisturiser:
 

🔵🔵 Perfect Moisturizer for Normal to Dry Skin

According to CreamScan analysis, La Roche-Posay Effaclar H Iso-Biome Moisturiser is intensely moisturizing, with a moisturizing rating of 8.0 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈9.0%) and Panthenol (est. ≈3.0%), and a high occlusivity of 6.1 out of 10, mainly due to the significant content of Squalane (est. ≈6.0%) and Dimethicone (est. ≈4.0%).

This type of moisturizer is ideal for people with normal skin who want intense hydration in a rich yet not overly thick formula. It combines a high concentration of humectants with a significant amount of occlusive ingredients to provide effective dual-action moisturizing.

The product’s occlusive profile suggests a texture that is rich and creamy but not overly thick, offering the potential to absorb into the skin without leaving a greasy afterfeel in most cases.

This product may also be a good choice for people with dry (but not very dry) skin for daily hydration, as it strikes a balance between significant moisturizing potential and a texture that is not too thick.

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

🟣 Modest Anti-Wrinkle Efficacy

According to CreamScan analysis, La Roche-Posay Effaclar H Iso-Biome Moisturiser has a modest level of anti-wrinkle efficacy, rated 3.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈2.0%),
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
📌 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 additional anti-wrinkle effects through its moisturizing action.

Based on the ingredient list analysis, La Roche-Posay Effaclar H Iso-Biome Moisturiser is rich (> 5%) in soothing ingredients, particularly Panthenol (est. ≈3.0%) and Niacinamide (est. ≈2.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.
