Review

Results you may expect from using Q + A Caffeine Eye Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Q + A Caffeine Eye Serum:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.

How moisturizing is it?

Quite moisturizing: Q + A Caffeine Eye Serum has a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Propylene Glycol (est. ≈6.0%), Betaine (est. ≈4.0%) and Pentylene Glycol (est. ≈3.0%).

Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

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

Anti-wrinkle efficacy

According to CreamScan analysis, Q + A Caffeine Eye Serum has a zero anti-wrinkle rating.

It contains some ingredients marketed as effective in reducing wrinkles, specifically Caffeine, Camellia Sinensis Leaf Extract, and Lactobacillus Ferment. 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 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. %75
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.
Propylene Glycol
Est. %6
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.
Betaine
Est. %4
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.
Pentylene Glycol
Est. %3
Function
Origin
Pentylene Glycol

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.

Caffeine
Est. %2
Function
Origin
CaffeineAn 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).

Collagen
Est. %1.3
Function
Origin
CollagenA protein that builds all human tissues, especially skin and joints. It is used as a moisturizing humectant ingredient in skincare.
Biosaccharide Gum-1
Est. %1
Function
Origin
Biosaccharide Gum-1A polysaccharide with humectant moisturizing and soothing properties.
Camellia Sinensis Leaf Extract
Est. %0.3
Function
Origin
Camellia Sinensis Leaf ExtractAn 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.
Punica Granatum Extract
Est. %0.3
Function
Origin
Punica Granatum ExtractAn extract made from pomegranate fruit. The fleshy and juicy part of the fruit mainly contains antioxidant red pigments and polyphenols. The rinds contain large amounts of tannins, which are astringent and leave the skin feeling tightened and refreshed.

Leuconostoc/Radish Root Ferment Filtrate
Est. %0.3
Function
Origin
Leuconostoc/Radish Root Ferment FiltrateA biotechnological fermentation ingredient that is created by feeding radish root to Leuconostoc kimchii. It allegedly contains organic acids and a mixture of peptides known as bacteriocins – which have antimicrobial activity.
Sodium Phytate
Est. %0.3
Function
Origin
Sodium PhytateSodium phytate is a chelating agent that serves to remove heavy metal ions from water. Removing metal ions helps other ingredients, such as antioxidants and preservatives, to perform better and keep products from separating.
Glycerin
Est. %0.3
Function
Origin
Glycerin

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

Lactobacillus Ferment
Est. %0.3
Function
Origin
Lactobacillus FermentA biotechnological product – a mixture of metabolic products of Lactobacillus culture. Some Lactobacillus forms have been reported to have anti-wrinkle and barrier repairing effects, as well as able to improve skin hydration, elasticity, and gloss.
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.
Alcohol
Est. %0.3
Function
Origin
AlcoholAn effective antimicrobial ingredient that kills bacteria, fungi, and even some viruses. It is also an excellent solvent and astringent. Alcohol helps to create lighter and less viscous products. It can, however, be dehydrating and skin-sensitizing.
Sodium Levulinate
Est. %0.3
Function
Origin
Sodium LevulinateA sodium salt of levulinic acid that is used as an antimicrobial and preservative agent, inhibiting the growth of harmful bacteria in a product.
Sodium Hydroxide
Est. %0.3
Function
Origin
Sodium Hydroxide

An ingredient that is able to bring the pH of a product up, thereby making it less harsh on the skin.

Glyceryl Caprylate
Est. %0.3
Function
Origin
Glyceryl CaprylateA waxy solid derived from vegetable oils that has emollient and emulsifying properties. It is also known to boost the efficacy of organic acid preservatives by destabilizing the microbe's cell membrane.
Sodium Anisate
Est. %0.3
Function
Origin
Sodium AnisateA natural preservative with a sweet scent.
Lactic Acid
Est. %0.3
Function
Origin
Lactic AcidThe most popular AHA in skincare and less irritating than glycolic acid. It can be naturally found in sour milk. It is a humectant moisturizing, pH stabilizing, and gently exfoliating ingredient, able to soften dry, cracked, and peeling skin.
