Review

Results you may expect from using NARS Optimal Brightening Concentrate Facial Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using NARS Optimal Brightening Concentrate Facial Serum:

  • Significant moisturizing. It has a moisturizing rating of 6.5 out of 10.

How moisturizing is it?

Highly moisturizing: NARS Optimal Brightening Concentrate Facial Serum has a moisturizing rating of 6.5 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a very high humectancy of 9.8 out of 10, primarily due to the substantial concentration of Butylene Glycol (est. ≈4.0%) and Glycerin (est. ≈3.0%), and a moderate occlusivity of 3.2 out of 10, mainly due to the significant content of Dimethicone (est. ≈6.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, NARS Optimal Brightening Concentrate Facial Serum has a zero anti-wrinkle rating.

It 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 generate 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 some anti-wrinkle effects through its moisturizing action.

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

Ingredients explained

Water
Est. %70
Function
Origin
The 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.
Dimethicone
Est. %6
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. %4
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.
Glycerin
Est. %3
Function
Origin

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

Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer
Est. %2
Function
Origin

Hydrogenated Polyisobutene
Est. %1.5
Function
Origin
A viscous liquid that makes a great oil base due to its smooth sensorial profile. It has emollient features, including good spreadability and little tack upon application. It also has the added benefit of being able to thicken products.
PEG-10 Dimethicone
Est. %1.3
Function
Origin
A polyethylene-based emulsifying ingredient. It has a water-loving portion and an oil-loving portion that help to keep the water and oil phases connected to form an emulsion.
PEG-32
Est. %1
Function
Origin
A synthetic water-loving moisturizer that produces water gels.
PEG-6
Est. %0.3
Function
Origin
A synthetic alcohol that moisturizes skin and dissolves many other ingredients.
3-O-Ethyl Ascorbic Acid
Est. %0.3
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.
Phenoxyethanol
Est. %0.3
Function
Origin
The 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.
Sodium Citrate
Est. %0.3
Function
Origin
A salt of citric acid that has a salty and tart flavor and is used as a fragrance. It is mildly basic, meaning that its addition to a skincare product can adjust the pH upward.
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.
Citric Acid
Est. %0.3
Function
Origin
A gently exfoliating AHA that helps to remove the top layer of dead skin cells. In comparison to other AHAs, citric acid has been shown to be one of the least effective. It is also very commonly used as a stabilizing and pH-controlling agent.
Ethylhexylglycerin
Est. %0.3
Function
Origin
A 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.
Dimethicone/Vinyl Dimethicone Crosspolymer
Est. %0.3
Function
Origin
This ingredient can refer to several kinds of dimethicone crosspolymers. Like other silicones, it makes products feel slippery and non-greasy but can also increase the thickness or improve the water-resistance of a formula.
Hydrolyzed Viola Tricolor Extract
Est. %0.3
Function
Origin

Sea Water
Est. %0.3
Function
Origin
A water obtained from oceans, seas, and large saltwater lakes. The water has been purified, and what remains is a complex mixture of various mineral salts that have beneficial effects on the skin. Sea water is used as a humectant and a solvent.
Potassium Hydroxide
Est. %0.3
Function
Origin
A very alkaline ingredient, meaning that it has a high pH. Potassium hydroxide is therefore useful in bringing a low pH in a cosmetic product up to a more neutral, skin-safe level.
Agar
Est. %0.3
Function
Origin
A multifunctional jelly derived from red algae that can thicken water-based products.
Saccharomyces Cerevisiae Extract
Est. %0.3
Function
Origin
A fungi ingredient made from baker's yeast. It is moisturizing and contains various beneficial compounds that support skin health. Among these is beta-glucan, the praised wound healing polysaccharide.

Est. %0.3
Function
Origin

Trisodium EDTA
Est. %0.3
Function
Origin
A chelating agent designed to encapsulate potentially harmful heavy metal ions that enter the formula through the water source. Once encapsulated, these heavy metal ions become inert.
Algae Extract
Est. %0.3
Function
Origin
The name describes any extract made from any kind of algae. Algae extracts are moisturizing humectants – the gelatin-like polysaccharides bind and retain water, thereby hydrating the skin. Algae is a rich source of emollient and antioxidant compounds.

Origin
An extract from a mixture of various tiny marine animals, algae, seaweeds, and microscopic organisms jointly called plankton. One patent refers to it as a moisturizing humectant ingredient.
Alumina
Est. %0.3
Function
Origin
A mineral derived from the metal ore known as aluminum. It is commonly used as an abrasive and also acts as a thickening viscosity controlling agent (and thus as a bulking agent). Alumina is also a great opacifier.
Citral
Est. %0.3
Function
Origin
A fragrant compound found in many essential oils (especially lemon myrtle and lemongrass essential oil). It has a sweet, lemon-like scent. People with sensitive skin should try to avoid products with citral, or at least do a patch test before using.

Est. %0.3
Function
Origin
Also known as iron (III) oxide, this ingredient is a yellow-colored pigment that can either be derived from minerals or produced synthetically. It adds yellow tones to cosmetic products.
