Lightweight Moisturizer Suitable for Oily Skin

According to CreamScan analysis, Biologique Recherche Serum Yall~O2 Fundamental Hydration Elixir is lightly moisturizing, with a moisturizing rating of 2.1 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 0.2 out of 10 and a moderate humectancy of 4.0 out of 10, primarily due to Xylitylglucoside (est. ≈1.5%), Sodium Hyaluronate (est. ≈1.3%) and Anhydroxylitol (est. ≈0.3%).

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.

A Humectant Add-on for Any Skincare Routine

But it’s not limited to 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.

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.
