Review

Results you may expect from using Sobel Skin Rx 35% Vitamin C Face Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Sobel Skin Rx 35% Vitamin C Face Serum:

  • Light moisturizing. It has a moisturizing rating of 2.0 out of 10.
  • Antioxidant protection.

How moisturizing is it?

Lightly moisturizing: Sobel Skin Rx 35% Vitamin C Face Serum has a moisturizing rating of 2.0 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 moderate humectancy of 4.1 out of 10, primarily due to Glycerin (est. ≈1.5%), Chondrus Crispus Extract (est. ≈1.3%) and Sodium Hyaluronate (est. ≈1.0%).

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, Sobel Skin Rx 35% Vitamin C Face Serum has a zero anti-wrinkle rating.

It contains some ingredients marketed as effective in reducing wrinkles, specifically Tetrahexyldecyl Ascorbate, Sodium Ascorbyl Phosphate, and Magnesium Ascorbyl Phosphate. 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 generate 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 some anti-wrinkle effects through its moisturizing action.

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

Antioxidant benefits

We estimate that Sobel Skin Rx 35% Vitamin C Face Serum is rich (> 3%) in antioxidants, specifically Tetrahexyldecyl Ascorbate (est. ≈6.0%), Sodium Ascorbyl Phosphate (est. ≈4.0%) and Magnesium Ascorbyl Phosphate (est. ≈3.0%).

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. %80
Function

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.
Tetrahexyldecyl Ascorbate
Est. %6
Function
Origin
A lipid-soluble form of vitamin C that is more stable and less irritating than ascorbic acid. According to a recent clinical study, THDA has all the capabilities of regular vitamin C, including anti-wrinkle and anti-pigment activity.
Sodium Ascorbyl Phosphate
Est. %4

Origin
The most researched derivative of vitamin C. It boosts collagen synthesis, thereby improving skin structure and elasticity. SAP is effective in the treatment of inflamed acne lesions and has a weak but positive effect on pigmentation issues.
Magnesium Ascorbyl Phosphate
Est. %3
Function
Origin
One of the best-researched derivatives of vitamin C. It is more resistant to light and air and retains all the properties of ascorbic acid – antioxidant, collagen-boosting, and anti-pigmentation, but with less irritation.
