Review

Results you may expect from using Oh K! Hyaluronic Acid Hydrogel Sheet Mask:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Oh K! Hyaluronic Acid Hydrogel Sheet Mask:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.
  • Considerable anti-wrinkle efficacy: Oh K! Hyaluronic Acid Hydrogel Sheet Mask has an anti-wrinkle rating of 4.5 out of 10, indicating a moderate ability to reduce wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: Oh K! Hyaluronic Acid Hydrogel Sheet Mask has a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%) and Niacinamide (est. ≈3.0%).

Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

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

Anti-wrinkle efficacy

According to CreamScan analysis, Oh K! Hyaluronic Acid Hydrogel Sheet Mask has a moderate anti-wrinkle rating of 4.5 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈3.0%),
 one of the most effective and well-researched anti-wrinkle ingredients.
 
Among others, Oh K! Hyaluronic Acid Hydrogel Sheet Mask also contains some ingredients marketed as effective in reducing wrinkles, specifically Centella Asiatica Extract, Adenosine, and Magnesium Ascorbyl Phosphate. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do 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, could deliver additional anti-wrinkle efficacy through its moisturizing action.
 

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

Antioxidant benefits

We estimate that Oh K! Hyaluronic Acid Hydrogel Sheet Mask is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈3.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.
