Review

Results you may expect from using iS Clinical Youth Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using iS Clinical Youth Serum:

  • Light moisturizing. It has a moisturizing rating of 3.0 out of 10.
  • Some anti-wrinkle efficacy: iS Clinical Youth Serum has an anti-wrinkle rating of 3.0 out of 10 so you may expect some, although limited, effect on wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Lightly moisturizing: iS Clinical Youth Serum has a moisturizing rating of 3.0 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 high humectancy of 6.0 out of 10, primarily due to the high content of Glycerin (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, iS Clinical Youth Serum has a slight anti-wrinkle rating of 3.0 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Asiaticoside (est. ≈0.3%), 
 derived from the plant Centella asiatica, an ingredient with moderate anti-wrinkle efficacy confirmed by one study.
 
Among others, iS Clinical Youth Serum also contains some ingredients marketed as effective in reducing wrinkles, specifically Caffeine, Pseudoalteromonas Ferment Extract, Tripeptide-10 Citrulline, Tripeptide-1, Haberlea Rhodopensis Leaf Extract, Retinyl Palmitate, Ascorbyl Palmitate, Asiatic Acid, and some others. 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 iS Clinical Youth Serum is rich (> 3%) in antioxidants, specifically Caffeine (est. ≈4.0%).

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.

Ingredients explained

Water
Est. %75
Function
Origin
The most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
PVP
Est. %6
Function
Origin
An excellent film-former used in hairsprays, peel-off masks, and even some self-tanning products. These films are strong and hold onto the skin.
Caffeine
Est. %4
Function

A small, skin-identical peptide that boosts collagen renewal in the skin and improves other structural proteins. It may have trouble penetrating the skin in this form, so palmitic acid or biotin is usually added to it.

Lecithin
Est. %0.3
Function
Origin
A humectant, emollient, and emulsifier best suited for water-in-oil emulsions. Lecithin can come from sunflowers, soy, and eggs. The downside to lecithin is that it causes an extra burden on the formula’s preservative because it is nutritious.
Butylene Glycol
Est. %0.3
Function
Origin
A clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.
Xanthan Gum
Est. %0.3
