Key Benefits of COSRX Advanced Snail Peptide Eye Cream

 
These are the key benefits you can expect from using COSRX Advanced Snail Peptide Eye Cream:
 

🔵🔵 Perfect Moisturizer for Normal to Dry Skin with a Balanced Texture, Neither Too Light nor Too Heavy

According to CreamScan analysis, COSRX Advanced Snail Peptide Eye Cream is highly moisturizing, with a moisturizing rating of 7.0 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Snail Secretion Filtrate (est. ≈45.0%) and Butylene Glycol (est. ≈22.0%), and a moderate occlusivity of 4.0 out of 10, mainly due to the high content of Helianthus Annuus (Sunflower) Seed Oil (est. ≈6.0%).

This type of moisturizer is ideal for people with normal skin who want maximum hydration in a formula with a balanced texture - neither too light nor too heavy. It combines a very high concentration of humectants with a moderate amount of occlusive ingredients to deliver effective dual-action moisturizing for normal skin.

This product may also be a good choice for people with normal to dry skin for daily hydration.

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

🟣🟣 Considerable Anti-Wrinkle Efficacy

According to CreamScan analysis, COSRX Advanced Snail Peptide Eye Cream has a moderate anti-wrinkle rating of 4.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈3.0%),
 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, COSRX Advanced Snail Peptide Eye Cream also contains some ingredients often marketed as effective in reducing wrinkles, specifically Snail Secretion Filtrate, Adenosine, Copper Tripeptide-1, Acetyl Hexapeptide-8, Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-1, and Palmitoyl Tetrapeptide-7. 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 COSRX Advanced Snail Peptide Eye Cream is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈3.0%).

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.

Things to Be Aware Of: COSRX Advanced Snail Peptide Eye Cream

 
CreamScan identified a few things to consider before adding COSRX Advanced Snail Peptide Eye Cream to your skincare routine:
 

⚠️ Contains Snail Secretion Filtrate –  a Popular Ingredient with Limited Proven Clinical Efficacy

COSRX Advanced Snail Peptide Eye Cream contains Snail Secretion Filtrate (SSF, SCA), a purified form of snail mucin. Snail Secretion Filtrate is widely promoted for its supposed skincare benefits, including hydration, skin repair, wound healing, and anti-aging. CreamScan conducted an investigation into clinical trials evaluating the potential efficacy of SSF and found no convincing evidence to support its claimed benefits beyond basic moisturization. The full article is available here.

Water
Est. %2
Function
Origin

Palmitic AcidA saturated fatty acid used in skincare as a strongly occlusive moisturizer and barrier repairing, emollient ingredient. It is a waxy-looking, white solid. Palmitic acid can be commonly found in animal and vegetable fats, notably palm oil.
Arginine
Est. %1
Function
Origin
ArginineA humectant amino acid used to attract water to the skin’s surface. It is a part of the skin's Natural Moisturizing Factor, a mixture of various compounds that keeps the skin’s surface well hydrated. Arginine can also be used as a pH adjuster.

Betaine
Est. %0.3
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.
Cetearyl Olivate
Est. %0.3
Function
Origin
Cetearyl Olivate

A multifunctional ingredient derived from plants that primarily serves as an emulsifier. Supplied as a waxy ivory-colored flake, it can also be used as an emollient and slip modifier that gives a product an overall light, silky finish.

Sorbitan Olivate
Est. %0.3
Function
Origin
Sorbitan OlivateAn ester of sorbitol (a type of sugar alcohol) and olive oil fatty acids. It is used as an emulsifying agent to stabilize oil droplets in water (or vice versa).
Sodium Polyacrylate
Est. %0.3
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.
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.
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.

Est. %0.3
Function
Origin
Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate CopolymerAn emulsion stabilizer and thickener that helps to create a pleasant, satiny, and light formula texture. It works by forming a gel-like network within water or oil, which both stabilizes other ingredients and produces a thickening effect.
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.

Adenosine
Est. %0.3
Function
Origin
Adenosine

A key molecule responsible for energy transportation, signaling, and enzyme activity. Adenosine is a popular anti-wrinkle ingredient, however, the key study about its anti-wrinkle efficacy (1) does not meet CreamScan Research Evaluation Standards as it is not double-blind.

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.
