Review

Results you may expect from using Numbuzin No.5 Vitamin Boosting Essential Toner:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Numbuzin No.5 Vitamin Boosting Essential Toner:

  • Moderate moisturizing. It has a moisturizing rating of 5.1 out of 10.
  • Considerable anti-wrinkle efficacy: Numbuzin No.5 Vitamin Boosting Essential Toner has an anti-wrinkle rating of 4.6 out of 10, indicating a moderate ability to reduce wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: Numbuzin No.5 Vitamin Boosting Essential Toner has a moisturizing rating of 5.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.2 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈4.0%) and Niacinamide (est. ≈3.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Numbuzin No.5 Vitamin Boosting Essential Toner has a moderate anti-wrinkle rating of 4.6 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

  • Niacinamide (est. ≈3.0%),
     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.
Among others, Numbuzin No.5 Vitamin Boosting Essential Toner also contains some ingredients marketed as effective in reducing wrinkles, specifically 3-O-Ethyl Ascorbic Acid, Adenosine, Acetyl Hexapeptide-8, Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-1, and Palmitoyl Tetrapeptide-7. 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 Numbuzin No.5 Vitamin Boosting Essential Toner is rich (> 3%) in antioxidants, specifically Niacinamide (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. %75
Function
Origin
WaterThe 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.
Dipropylene Glycol
Est. %6
Function
Origin
Dipropylene GlycolA clear, colorless liquid that has several uses. One of its main functions is as a solvent. Dipropylene glycol is also used to reduce the thickness of skincare products.
Glycerin
Est. %4
Function
Origin
Glycerin

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

Niacinamide
Est. %3
Function
Origin
Niacinamide

Also known as vitamin B3, this ingredient is a true superstar with confirmed moisturizing, anti-acne, hyperpigmentation, and antioxidant benefits. Two studies confirm its significant anti-wrinkle efficacy.

1,2-Hexanediol
Est. %2
Function
Origin
1,2-HexanediolA multi-functional formula helper. It is a well-studied preservtive against bacteria and can help pigments and fragrances disperse evenly in a formula.
Butylene Glycol
Est. %1.5
Function
Origin
Butylene GlycolA 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.

Acrylates/C10-30 Alkyl Acrylate Crosspolymer
Est. %0.3
Function
Origin
Acrylates/C10-30 Alkyl Acrylate CrosspolymerA synthetic ingredient that is used to thicken water and alcohol. It results in a more lightweight formula and is commonly found in gel products.
Tromethamine
Est. %0.3
Function
Origin
TromethamineAn ingredient based on amino acids that is commonly used as a pH adjuster. It has a high pH, which means that it is basic (alkaline), so adding tromethamine to a skincare product will increase its overall pH level.
Erythritol
Est. %0.3
Function
Origin
ErythritolA naturally occurring sweetener that hydrates skin by drawing in water.
Pentylene Glycol
Est. %0.3
Function
Origin

3-O-Ethyl Ascorbic Acid
Est. %0.3
Function
Origin
3-O-Ethyl Ascorbic AcidA derivative of vitamin C. Its stability in skincare formulations is better than ascorbic acid’s, although clinical studies are yet to indicate whether it has the same collagen-boosting benefits.
Ethylhexylglycerin
Est. %0.3
Function
Origin
EthylhexylglycerinA 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.
Polyglyceryl-4 Caprate
Est. %0.3
Function
Origin
Polyglyceryl-4 CaprateA natural surfactant that softens the appearance of skin and forms oil and water mixtures.
Adenosine
Est. %0.3
Function
Origin
Adenosine

A key molecule responsible for energy transportation, signaling, and enzyme activity. Adenosine is a popular anti-wrinkle ingredient, however, the key study about its anti-wrinkle efficacy (1) does not meet CreamScan Research Evaluation Standards as it is not double-blind.

Glutathione
Est. %0.3
Function
Origin
GlutathioneA naturally occurring tripeptide that combats free radicals and acts as a reducing agent.
Hydrogenated Lecithin
Est. %0.3
Function
Origin
Hydrogenated LecithinA version of plain lecithin that has been saturated with hydrogen atoms. This ingredient can be derived from plants, like soy or sunflower, from egg yolks, or made synthetically. Its major function is to emulsify water and oils.
Disodium EDTA
Est. %0.3
Function
Origin
Disodium EDTAA synthetic chelator that helps to maintain the look and smell of a product by 'locking up' troublesome metal ions.

Decyl Glucoside
Est. %0.3
Function
Origin
Decyl GlucosideA surfactant that can function as both a cleansing agent and emulsifier. As a cleansing agent, it is very mild on the skin. As an emulsifier, decyl glucoside will produce oil-in-water emulsions. It is naturally derived from vegetable oils and starch.
Caprylyl Glycol
Est. %0.3
Function
Origin
Caprylyl GlycolAn emollient that improves product spreadability and offers a silky feel on the skin. It also acts as a preservative booster that improves the efficacy of other preservatives. According to the manufacturer, it is also a humectant moisturizer.
Ceramide NP
Est. %0.3
Function
Origin
Ceramide NPAlso known as ceramide 3, it is the most common ceramide in our skin. It helps to restore the skin’s lipid barrier and alleviate the symptoms of dry and cracked skin. Research has shown that skin suffering from conditions such as AD lacks ceramides.
Ascorbic Acid
Est. %0.3
Function
Origin
Ascorbic Acid

Also known as vitamin C, this multi-benefit ingredient has proven anti-wrinkle, antioxidant, and anti-pigmentation efficacy. It degrades easily when exposed to air and light, so it requires proper packaging to maintain its stability.

Bisabolol
Est. %0.3
Function
Origin
BisabololAn anti-inflammatory compound found naturally in German chamomile essential oil. It has a pleasant, sweet, and floral scent. Bisabolol also has soothing and anti-inflammatory properties but can cause an allergic reaction in more sensitive individuals.
