Key Benefits of Isntree Hyper Vitamin C 23 Serum

 
These are the key benefits you can expect from using Isntree Hyper Vitamin C 23 Serum:
 

Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Isntree Hyper Vitamin C 23 Serum is quite moisturizing, with a moisturizing rating of 4.8 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 very high humectancy of 9.4 out of 10, primarily due to the high content of Propanediol (est. ≈4.0%) and Betaine (est. ≈3.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients.

It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

A Humectant Boost for Any Skincare Routine

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

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

Modest Anti-Wrinkle Efficacy

According to CreamScan analysis, Isntree Hyper Vitamin C 23 Serum has a modest level of anti-wrinkle efficacy, rated 2.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈23.0%), 
 or Vitamin C, a popular ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
 
Among others, Isntree Hyper Vitamin C 23 Serum also contains Adenosine, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Adenosine 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, can deliver some anti-wrinkle effects through its moisturizing action.
 

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

Rich in Skin-Protecting Antioxidants

We estimate that Isntree Hyper Vitamin C 23 Serum is rich (> 3%) in antioxidants, specifically Ascorbic Acid (est. ≈23.0%).

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.

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Ingredients explained

Water
Est. %60
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.
Ascorbic Acid
Est. %23
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.

Propanediol
Est. %4
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Betaine
Est. %3
Function
Origin
BetaineAn ingredient derived from the sucrose in sugar beets. It has a negative chemical charge and a positive chemical charge on the same molecule. This allows betaine to be hygroscopic or humectant and thus provide moisturization by drawing water to the skin.
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.
Polyglycerin-3
Est. %1.5
Function
Origin
Polyglycerin-3
Tromethamine
Est. %1.3
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.
Ethyl Ether
Est. %1
Function
Origin
Ethyl Ether
Hydroxyethyl Urea
Est. %0.3
Function
Origin
Hydroxyethyl UreaHydroxyethyl urea is a synthetic derivative of regular urea (read about it here). This ingredient, similarly to urea, is humectant moisturizing and helps to retain more water to the skin’s surface, leaving it more moisturized. There aren't any studies that analyze the effects of this ingredient in great detail.
Betula Platyphylla Japonica Juice
Est. %0.3
Function
Origin
Betula Platyphylla Japonica JuiceA fresh sap obtained from the Asian white birch. It contains various antioxidant compounds and is claimed to promote hair growth.
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.
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.

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.
Panthenol
Est. %0.3
Function
Origin
PanthenolA popular soothing and moisturizing derivative of vitamin B5. Panthenol is particularly beneficial for dry, flaking, burned, or damaged skin. It is used to alleviate the symptoms of a rash, dermatitis, eczema, chapped lips, and sunburn.
Gardenia Florida Fruit Extract
Est. %0.3
Function
Origin
Gardenia Florida Fruit ExtractDerived from the dark orange fruits of a Chinese flowering shrub called Gardenia florida, this extract acts as a yellow pigment.
Dextrin
Est. %0.3
Function
Origin
DextrinA partially hydrolyzed potato starch, most commonly used as a viscosity controlling and binding agent. When dispersed into water, it can create textures ranging from a thick paste to a soft gel.
Tocopherol
Est. %0.3
Function
Origin
Tocopherol

Simply another name for vitamin E. Tocopherol is a fantastic ingredient and especially beneficial for dry and inflamed skin. It has occlusive moisturizing, emollient, antioxidant, and photoprotective properties.
