Review

Results you may expect from using Yon-Ka Hydra No1 Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Yon-Ka Hydra No1 Serum:

  • Moderate moisturizing. It has a moisturizing rating of 5.4 out of 10.
  • Little anti-wrinkle effect: Yon-Ka Hydra No1 Serum has an anti-wrinkle rating of 0.6 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

How moisturizing is it?

Quite moisturizing: Yon-Ka Hydra No1 Serum has a moisturizing rating of 5.4 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a high humectancy of 7.8 out of 10, primarily due to the substantial concentration of Imperata Cylindrica Root Extract (est. ≈3.0%) and Glycerin (est. ≈2.0%), and a moderate occlusivity of 3.0 out of 10, solely because of the significant content of Squalane (est. ≈6.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Yon-Ka Hydra No1 Serum 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 Hydra No1 Serum 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.
