Review

Results you may expect from using cyrene Brightening & Firming Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using cyrene Brightening & Firming Serum:

  • Light moisturizing. It has a moisturizing rating of 3.1 out of 10.
  • Little anti-wrinkle effect: cyrene Brightening & Firming Serum has an anti-wrinkle rating of 1.2 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Lightly moisturizing: cyrene Brightening & Firming Serum has a moisturizing rating of 3.1 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 0.2 out of 10 and a moderate humectancy of 5.9 out of 10, primarily due to the high content of Glycerin (est. ≈3.0%) and Propylene Glycol (est. ≈2.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, cyrene Brightening & Firming Serum has a minimal anti-wrinkle rating of 1.2 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈4.0%),
 highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.
 
Among others, cyrene Brightening & Firming Serum also contains 3-O-Ethyl Ascorbic Acid, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of 3-O-Ethyl Ascorbic Acid 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, 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 cyrene Brightening & Firming Serum is rich (> 3%) in antioxidants, specifically 3-O-Ethyl 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

Water
Est. %80
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.
3-O-Ethyl Ascorbic Acid
Est. %6
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.
Glycolic Acid
Est. %4
Function
Origin
Glycolic Acid

The second most used AHA (after lactic acid) known for its potent exfoliating and smoothing effects. It increases skin cell turnover, which is beneficial for treating acne. When used in peels, glycolic acid has confirmed anti-wrinkle efficacy, though it is less effective in leave-on products like creams and serums.

Glycerin
Est. %3
Function
Origin
Glycerin

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

Propylene Glycol
Est. %2
Function
Origin
Propylene GlycolA clear, thick, odorless liquid of synthetic origin. Its main function is to stabilize cosmetic products exposed to varying temperatures. It is also a moderately strong humectant with similar properties to glycerin.
Dipropylheptyl Carbonate
Est. %1.5
Function
Origin
Dipropylheptyl CarbonateDescription is coming soon
Sodium Polyacrylate
Est. %1.3
Function
Origin
Sodium PolyacrylateThis white powder is primarily used as a viscosity controlling agent. It is added to the water phase, which then thickens to form a clear gel. Sodium polyacrylate can also serve as an emollient, absorbent, and emulsion stabilizer.
Sodium Bicarbonate
Est. %1
Function
Origin
Sodium BicarbonateA sodium salt that increases pH and removes dead skin cells.
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.

Tocopheryl Acetate
Est. %0.3
Function
Origin
Tocopheryl Acetate

An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.

Xanthan Gum
Est. %0.3
Function
Origin
Xanthan GumA 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.
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.

Phenoxyethanol
Est. %0.3
Function
Origin
PhenoxyethanolThe most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
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.
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.
