Review

Results you may expect from using Akind Sleep Tight Firming Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Akind Sleep Tight Firming Serum:

  • Moderate moisturizing. It has a moisturizing rating of 4.4 out of 10.
  • Some anti-wrinkle efficacy: Akind Sleep Tight Firming Serum has an anti-wrinkle rating of 3.1 out of 10 so you may expect some, although limited, effect on wrinkles.
  • Soothing: Akind Sleep Tight Firming Serum contains a high concentration of soothing ingredients, which may help to reduce irritation and calm the skin.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: Akind Sleep Tight Firming Serum has a moisturizing rating of 4.4 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a very high humectancy of 8.8 out of 10, primarily due to the high content of Cinnamomum Zeylanicum Bark Extract (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, Akind Sleep Tight Firming Serum has a slight anti-wrinkle rating of 3.1 out of 10.

It contains 4 active ingredients with proven anti-wrinkle efficacy:

  • Retinol (est. ≈0.1%),
     the most effective non-prescription ingredient with well-proven efficacy to reduce wrinkles.
  • Niacinamide (est. ≈0.3%),
     one of the most effective and well-researched anti-wrinkle ingredients.
  • Ascorbic Acid (est. ≈0.3%),
     or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
  • Glycolic Acid (est. ≈0.3%),
     highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.
Among others, Akind Sleep Tight Firming Serum also contains some ingredients marketed as effective in reducing wrinkles, specifically Tripeptide-1, Palmitoyl Tripeptide-5, Palmitoyl Pentapeptide-4, Palmitoyl Tetrapeptide-7, and Camellia Sinensis Leaf Extract. 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 Akind Sleep Tight Firming Serum is rich (> 3%) in antioxidants, specifically Cinnamomum Zeylanicum Bark Extract (est. ≈3.0%) and Thymus Vulgaris (Thyme) Extract (est. ≈2.0%).

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, Akind Sleep Tight Firming Serum is rich (> 5%) in soothing ingredients, particularly Zinc Chloride (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.
