How moisturizing is it?

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈7.5%) and Niacinamide (est. ≈5.0%), and a moderate occlusivity of 3.2 out of 10, mainly due to the high content of Caprylic/Capric Triglyceride (est. ≈3.0%) and Phenyl Trimethicone (est. ≈2.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Saturday Skin Yuzu Vitamin C Sleep Mask has a very high anti-wrinkle rating of 8.6 out of 10.

It contains 3 active ingredients with proven anti-wrinkle efficacy:

  • Niacinamide (est. ≈5.0%),
     one of the most effective and well-researched anti-wrinkle ingredients.
  • Retinol (est. ≈0.1%),
     the most effective non-prescription ingredient with well-proven efficacy to reduce wrinkles.
  • Ascorbic Acid (est. ≈0.3%),
     or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
Among others, Saturday Skin Yuzu Vitamin C Sleep Mask also contains some ingredients marketed as effective in reducing wrinkles, specifically sh-Oligopeptide-1, sh-Polypeptide-1, and sh-Polypeptide-9. 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.
 

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

Antioxidant benefits

We estimate that Saturday Skin Yuzu Vitamin C Sleep Mask is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈5.0%).

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.

Skin soothing

Based on the ingredient list analysis, Saturday Skin Yuzu Vitamin C Sleep Mask is rich (> 5%) in soothing ingredients, particularly Niacinamide (est. ≈5.0%).

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.
