Anti-wrinkle efficacy

According to CreamScan analysis, Yon-Ka Vital 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 Vital Defense also contains contains Retinyl Palmitate and Ubiquinone, 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.
