Key Benefits of Isntree Green Tea Fresh Serum

 
These are the key benefits you can expect from using Isntree Green Tea Fresh Serum:
 

Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Isntree Green Tea Fresh Serum is quite moisturizing, with 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 Camellia Sinensis Leaf Extract (est. ≈75.0%), Butylene Glycol (est. ≈4.0%) and Glycerin (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 Green Tea Fresh Serum has a modest level of anti-wrinkle efficacy, rated 2.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈1.3%), 
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
Among others, Isntree Green Tea Fresh Serum also contains some ingredients marketed often as effective in reducing wrinkles, specifically Camellia Sinensis Leaf Extract, Adenosine, and Pueraria Lobata Root Extract. 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, 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 Green Tea Fresh Serum is rich (> 3%) in antioxidants, specifically Camellia Sinensis Leaf Extract (est. ≈75.0%).

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 and Calming Potential

Based on the ingredient list analysis, Isntree Green Tea Fresh Serum is rich (> 5%) in soothing ingredients, particularly Camellia Sinensis Leaf Extract (est. ≈75.0%).

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.

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

Camellia Sinensis Leaf Extract
Est. %75
Function
Origin
Camellia Sinensis Leaf Extract

An antioxidant green tea extract. In the deeper layers, it slows down the destruction of collagen, elastin, and hyaluronic acid – thus delaying the signs of aging. It also acts as an anti-acne, soothing, moisturizing, and emollient ingredient.

Water
Est. %6
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.
Butylene Glycol
Est. %4
Function
Origin
Butylene Glycol

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.

Glycerin
Est. %3
Function
Origin
Glycerin

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

Propanediol
Est. %2
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.
Dipropylene Glycol
Est. %1.5
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.
Niacinamide
Est. %1.3
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. %1
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.
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.
Hydroxyacetophenone
Est. %0.3
Function
Origin
HydroxyacetophenoneAn antioxidant compound that can be found in many plants, although it is manufactured synthetically for skincare purposes. It can boost the preservative action of other conservants.
Squalane
Est. %0.3
Function
Origin
SqualaneAn occlusive moisturizing and emollient compound that forms part of the skin’s sebum. The main source of squalane had always been shark liver. Now, however, it is manufactured synthetically or derived from plant oils, such as olive and peanut oil.
Ammonium Acryloyldimethyltaurate/VP Copolymer
Est. %0.3
Function
Origin
Ammonium Acryloyldimethyltaurate/VP CopolymerA polymeric ingredient that creates lightweight and refreshing gel textures. It also works as a viscosity controlling agent.
Allantoin
Est. %0.3
Function
Origin
AllantoinA fluffy, white powder that acts as a humectant due to its water-loving chemistry and as an exfoliant that helps to remove dead skin cells. It has also been shown to be very soothing to irritated and inflamed skin.
Carbomer
Est. %0.3
Function
Origin

Betaine
Est. %0.3
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.
Polyglyceryl-3 Methylglucose Distearate
Est. %0.3
Function
Origin
Polyglyceryl-3 Methylglucose DistearateA natural ingredient that produces oil and water mixtures with soft skin feel.
Cetearyl Alcohol
Est. %0.3
Function
