Key Benefits of Bioten Skin Moisture Face Cream Dry Sensitive Skin

 
These are the key benefits you can expect from using Bioten Skin Moisture Face Cream Dry Sensitive Skin:
 

🔵🔵🔵 Rich Moisturizer Perfect for Dry Skin

According to CreamScan analysis, Bioten Skin Moisture Face Cream Dry Sensitive Skin is intensely moisturizing, with a moisturizing rating of 9.1 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. ≈6.0%) and Propanediol (est. ≈2.0%), and a very high occlusivity of 8.2 out of 10, mainly due to the significant content of Dimethicone (est. ≈9.0%) and Phenyl Trimethicone (est. ≈4.0%).

This type of moisturizer is ideal for people with dry skin who want intense hydration. It combines a high concentration of humectants and occlusive ingredients to provide effective dual-action moisturizing specifically for dry skin.

The occlusive profile of Bioten Skin Moisture Face Cream Dry Sensitive Skin suggests a rich, thick texture, making it perfectly suited for dry skin.

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

🟣 Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, Bioten Skin Moisture Face Cream Dry Sensitive Skin has a slight anti-wrinkle rating of 0.1 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈0.3%),
 or Vitamin C, a popular ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
 
Among others, Bioten Skin Moisture Face Cream Dry Sensitive Skin also contains Ascorbyl Palmitate, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Ascorbyl Palmitate provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.
 
While this does not categorically rule out the possibility that Ascorbyl Palmitate 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 contribute to 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 additional anti-wrinkle effects through its moisturizing action.
 

Please refer to the Ratings section below for details of the anti-wrinkle 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.
