Key Benefits of Iope Gluta Vitamin C Brightening Serum

 
These are the key benefits you can expect from using Iope Gluta Vitamin C Brightening Serum:
 

🔵 Lightweight Moisturizer Suitable for Oily Skin

According to CreamScan analysis, Iope Gluta Vitamin C Brightening Serum is lightly moisturizing, with a moisturizing rating of 3.2 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 1.4 out of 10 and a moderate humectancy of 4.9 out of 10, primarily due to Butylene Glycol (est. ≈1.8%), Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate (est. ≈1.0%) and Panthenol (est. ≈0.3%).

This product, when used alone as a moisturizer, can provide light humectant hydration in a fast-absorbing formula with a minimal amount of occlusive ingredients. This could work for people with oily skin who need a basic level of hydration.

💧  A Humectant Add-on for Any Skincare Routine

But it’s not limited to oily skin - since it contains a moderate amount of humectants, such a humectant add-on will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer.

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

🟣 Modest Anti-Wrinkle Efficacy

According to CreamScan analysis, Iope Gluta Vitamin C Brightening Serum has a modest level of anti-wrinkle efficacy, rated 2.9 out of 10.

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

1️⃣ Ascorbic Acid (est. ≈6.0%),
 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).
 
2️⃣ Niacinamide (est. ≈0.3%),
 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, Iope Gluta Vitamin C Brightening Serum also contains some ingredients often marketed as effective in reducing wrinkles, specifically 3-O-Ethyl Ascorbic Acid, Caffeine, Acetyl Glucosamine, Gluconolactone, and Ascorbyl Tetraisopalmitate. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards.
 
While this does not categorically rule out the possibility that these ingredients may reduce wrinkles, their efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.
 
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 additional 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 Iope Gluta Vitamin C Brightening Serum is rich (> 3%) in antioxidants, specifically Ascorbic Acid (est. ≈6.0%).

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 model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Ingredients explained

Rosa Damascena Flower Water
Est. %75
Function
Origin
Rosa Damascena Flower WaterA fragrant water that is leftover after the steam distillation of Damask rose petals. During this process, the essential oil floats to the surface of the water and is collected. The leftover water has a fresh, rosy scent.
Ascorbic Acid
Est. %6
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.

Tromethamine
Est. %2
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.
Dimethicone
Est. %1.9
Function
Origin
DimethiconeThe most common silicone in skincare. It forms a silky, smooth film on the skin’s surface and can help to prevent water loss. It also aids in wound healing and can treat and soften scars. Dimethicone is considered to be very safe for use.
Butylene Glycol
Est. %1.8
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.

Dipropylene Glycol

Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate
Est. %1
Function
Origin
Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate
Squalane
Est. %0.3

Acetyl Glucosamine
Est. %0.3
Function
Origin

Sodium Hyaluronate
Est. %0.3
Function
Origin
Sodium Hyaluronate

A sodium salt of famous hyaluronic acid. A potent humectant that hydrates the skin, supports collagen function, and fills out small wrinkles. Sodium hyaluronate also offers soothing and antioxidant properties.

Gluconolactone
Est. %0.3
Function
Origin

Glutathione
Est. %0.3
Function
Origin
GlutathioneA naturally occurring tripeptide that combats free radicals and acts as a reducing agent.
Pentylene Glycol
Est. %0.3
Function
Origin
Pentylene Glycol

Fragrance
Est. %0.3
Function
Origin
FragranceUnder trade secret law, manufacturers have the right not to disclose what exactly went into the fragrance and use the unspecific word Fragrance or Parfum instead. Many fragrances are highly allergenic.
Ascorbyl Tetraisopalmitate
Est. %0.3
Function
Origin
Ascorbyl Tetraisopalmitate
