Review

Results you may expect from using Iope Gluta Vitamin C Brightening Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Iope Gluta Vitamin C Brightening Serum:

  • Light moisturizing. It has a moisturizing rating of 3.2 out of 10.
  • Some anti-wrinkle efficacy: Iope Gluta Vitamin C Brightening Serum has an anti-wrinkle rating of 3.5 out of 10 so you may expect some, although limited, effect on wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Lightly moisturizing: Iope Gluta Vitamin C Brightening Serum has 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%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Iope Gluta Vitamin C Brightening Serum has a slight anti-wrinkle rating of 3.5 out of 10.

It contains 3 active ingredients with proven anti-wrinkle efficacy:

  • Ascorbic Acid (est. ≈6.0%),
     or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
  • Ascorbyl Tetraisopalmitate (est. ≈0.3%),
     the only derivative of Ascorbic acid with confirmed anti-wrinkle efficacy. This ingredient has below-average efficacy, proven by one study.
  • Niacinamide (est. ≈0.3%),
     one of the most effective and well-researched anti-wrinkle ingredients.
Among others, Iope Gluta Vitamin C Brightening Serum also contains some ingredients marketed as effective in reducing wrinkles, specifically 3-O-Ethyl Ascorbic Acid, Caffeine, Acetyl Glucosamine, and Gluconolactone. 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 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.

Ingredients explained

Rosa Damascena Flower Water
Est. %75
Function
Origin
A 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

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
An 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
The 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
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
Est. %1.5
Function
Origin
A 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.
3-O-Ethyl Ascorbic Acid
Est. %1.3
Function
Origin
A 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.
Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate
Est. %1
Function
Origin
Description is coming soon
Squalane
Est. %0.3
Function
Origin
An 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.
Caffeine
Est. %0.3
Function
Origin
An antioxidant compound that is obtained from coffee and tea leaves. It increases the microcirculation of blood in the skin and is claimed to be able to reduce the appearance of orange peel skin (although the research is lacking).
Sodium Chloride
Est. %0.3
Function
Origin

You’re definitely familiar with sodium chloride, even if you don’t think you are. It’s table salt! Salt works well with some cleansing ingredients (surfactants) to thicken them into gels. It also acts as a stabilizer for water-in-oil emulsions.

Panthenol
Est. %0.3
Function
Origin
A 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.
Acetyl Glucosamine
Est. %0.3
Function
Origin
A body-natural amino-saccharide used in skincare as an anti-pigment ingredient. Some other benefits of acetyl glucosamine include decreased skin flakiness, improved wound healing, and even a slight reduction in facial wrinkles.
Sodium Hyaluronate
Est. %0.3
Function
Origin

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
A PHA derived from glucose. It has exfoliating and humectant properties and acts as a penetration enhancer for other ingredients. It has also been shown to assist in the treatment of acne and the prevention of photoaging.
Glutathione
Est. %0.3
Function
Origin
A naturally occurring tripeptide that combats free radicals and acts as a reducing agent.
Pentylene Glycol
Est. %0.3
Function
Origin

A naturally or synthetically derived preservative that exhibits effective antifungal and antibacterial traits. It also acts as a booster for more traditional preservatives. Pentylene glycol can also serve as a moisturizing humectant and solvent.

Fragrance
Est. %0.3
Function
Origin
Under 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 (ATIP) is an oil-soluble derivative of ascorbic acid, or vitamin C. It is more stable than ascorbic acid, with studies supporting its collagen-boosting and anti-pigment effects.

Xanthan Gum
Est. %0.3
Function
Origin
A natural multi-functional ingredient that originates from fermented sugars. Xanthan gum acts as a viscosity-building agent to thicken skincare products. It is also an excellent stabilizer and works well to hold other ingredients together.
