Results you may expect from using 111SKIN Y Theorem Repair Serum NAC Y2:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using 111SKIN Y Theorem Repair Serum NAC Y2:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.
  • Little anti-wrinkle effect: 111SKIN Y Theorem Repair Serum NAC Y2 has an anti-wrinkle rating of 0.4 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: 111SKIN Y Theorem Repair Serum NAC Y2 has a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈45.0%), Sorbitol (est. ≈11.0%) and Aloe Barbadensis Extract (est. ≈4.0%).

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, 111SKIN Y Theorem Repair Serum NAC Y2 has a minimal anti-wrinkle rating of 0.4 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈0.3%),
 one of the most effective and well-researched anti-wrinkle ingredients.
 
Among others, 111SKIN Y Theorem Repair Serum NAC Y2 also contains Sodium Ascorbyl Phosphate, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Sodium Ascorbyl Phosphate provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does 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 111SKIN Y Theorem Repair Serum NAC Y2 is rich (> 3%) in antioxidants, specifically Aloe Barbadensis Extract (est. ≈4.0%) and Calendula Officinalis Extract (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.

Skin soothing

Based on the ingredient list analysis, 111SKIN Y Theorem Repair Serum NAC Y2 is rich (> 5%) in soothing ingredients, particularly Aloe Barbadensis Extract (est. ≈4.0%) and Calendula Officinalis Extract (est. ≈3.0%).

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.

Glycerin
Est. %45
Function
Origin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Water
Est. %22
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.
Sorbitol
Est. %11
Function
Origin
A sweet-tasting alcohol derived from glucose. Aside from its sweet taste (for which it is used as a very common sweetener), Sorbitol is also very good at retaining water and is used in skincare as a humectant.
Isopropyl Myristate
Est. %6
Function
Origin
A fast-spreading, cost-effective, non-greasy emollient that is typically used for lubrication, spreadability, or to remove “tackiness” from a product. Isopropyl Myristate is listed as a common comedogenic ingredient by acne.org.
Aloe Barbadensis Extract
Est. %4

Origin
An antioxidant extract from the gelatinous pulp of Aloe vera leaves with humectant moisturizing polysaccharide mucilage. It is suitable for irritated or eczema-prone skin.

An effective antimicrobial ingredient that kills bacteria, fungi, and even some viruses. It is also an excellent solvent and astringent. Alcohol helps to create lighter and less viscous products. It can, however, be dehydrating and skin-sensitizing.
Phenoxyethanol
Est. %1
Function
Origin
The most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.

Function
Origin
A synthetic ingredient with the ability to gel water. When used in emulsions, such as lotions and creams, carbomer can also act as an emulsion stabilizer.
Sodium Hydroxide
Est. %0.3
Function
Origin
An ingredient that is able to bring the pH of a product up, thereby making it less harsh on the skin.

Origin
Derived from horse chestnut seeds, this soothing extract contains an anti-inflammatory mixture called Aescin. It is suitable for inflamed and irritated skin.
Sodium Ascorbyl Phosphate
Est. %0.3
Function
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.
Ethylhexylglycerin
Est. %0.3
Function
Origin
A preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.

Riboflavin
Est. %0.3
Function
Origin
Riboflavin, also known as Vitamin B2, is used in skincare as a coloring agent due to its bright, brilliant orange-yellow color. The research shows that it is a good antioxidant and can protect the skin from UV-induced damage.
