Results you may expect from using Yon-Ka Age-Defense:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Yon-Ka Age-Defense:

  • Moderate moisturizing. It has a moisturizing rating of 5.9 out of 10.
  • Little anti-wrinkle effect: Yon-Ka Age-Defense has an anti-wrinkle rating of 0.6 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.
  • Soothing: Yon-Ka Age-Defense contains a high concentration of soothing ingredients, which may help to reduce irritation and calm the skin.

How moisturizing is it?

Quite moisturizing: Yon-Ka Age-Defense has a moisturizing rating of 5.9 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.8 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Biosaccharide Gum-1 (est. ≈6.0%) and Glycerin (est. ≈5.9%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Yon-Ka Age-Defense has a minimal anti-wrinkle rating of 0.6 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Ascorbyl Tetraisopalmitate (est. ≈0.3%),
 the only derivative of Ascorbic acid with confirmed anti-wrinkle efficacy. This ingredient has below-average efficacy, proven by one study.
 
Among others, Yon-Ka Age-Defense also contains contains Imperata Cylindrica Root Extract and Retinyl Palmitate, two ingredients marketed as effective in reducing wrinkles. 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.

Skin soothing

Based on the ingredient list analysis, Yon-Ka Age-Defense is rich (> 5%) in soothing ingredients, particularly Biosaccharide Gum-1 (est. ≈6.0%).

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.
