Review

Results you may expect from using COSRX AC Collection Calming Liquid Intensive:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using COSRX AC Collection Calming Liquid Intensive:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.
  • Some anti-wrinkle efficacy: COSRX AC Collection Calming Liquid Intensive has an anti-wrinkle rating of 3.1 out of 10 so you may expect some, although limited, effect on wrinkles.
  • Soothing: COSRX AC Collection Calming Liquid Intensive contains a high concentration of soothing ingredients, which may help to reduce irritation and calm the skin.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: COSRX AC Collection Calming Liquid Intensive 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 Butylene Glycol (est. ≈4.0%) and Sodium Lactate (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, COSRX AC Collection Calming Liquid Intensive has a slight anti-wrinkle rating of 3.1 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

  • Asiaticoside (est. ≈0.3%),
     derived from the plant Centella asiatica, an ingredient with moderate anti-wrinkle efficacy confirmed by one study.
  • Glycolic Acid (est. ≈0.3%),
     highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.
Among others, COSRX AC Collection Calming Liquid Intensive also contains contains Asiatic Acid and Madecassic Acid, two ingredients marketed as effective in reducing wrinkles. 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 COSRX AC Collection Calming Liquid Intensive is rich (> 3%) in antioxidants, specifically Propolis Extract (est. ≈75.0%).

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.

Skin soothing

Based on the ingredient list analysis, COSRX AC Collection Calming Liquid Intensive is rich (> 5%) in soothing ingredients, particularly Propolis Extract (est. ≈75.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.

Ingredients explained

Propolis Extract
Est. %75
Function
Origin
A famous bee product that has traditionally been used to treat inflammation and wounds. The extract is soothing and promotes skin healing.
Alcohol
Est. %6
Function
Origin
An 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.
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.
Sodium Lactate
Est. %3
Function
Origin
A sodium salt of lactic acid. Its main function is as a humectant but it can also serve as a pH adjuster. Additionally, sodium lactate can also be used as a chemical exfoliant due to its close chemical relation to lactic acid.
Dimethyl Sulfone
Est. %2
Function
Origin

Betaine
Est. %1.5
Function
Origin
An 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.
Lactic Acid
Est. %1.3
Function
Origin
The 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.
1,2-Hexanediol
Est. %1
Function
Origin
A multi-functional formula helper. It is a well-studied preservtive against bacteria and can help pigments and fragrances disperse evenly in a formula.
Glycolic Acid
Est. %0.3
Function
Origin

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.

Water
Est. %0.3
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.
Betaine Salicylate
Est. %0.3

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.
Allantoin
Est. %0.3
Function
Origin
A 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.
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.
Polysorbate 60
Est. %0.3
Function
Origin
An ester based on sorbitan. It is good for emulsifying water and oils together – specifically making oil-in-water emulsions. Polysorbate 60 is also said to give a product a notable fragrance.
Hydroxyethylcellulose
Est. %0.3
Function
Origin
A naturally-derived thickener that can form clear gel textures without the slimy feeling, unlike some other natural gel-formers.
Zinc PCA
Est. %0.3
Function
Origin
A two-part ingredient: Zinc helps to control sebum and bacteria in acne-prone skin, while skin-identical PCA is a moisturizing humectant. Zinc PCA may even boost collagen production and so is researched as a potential anti-wrinkle ingredient.
Melaleuca Alternifolia (Tea Tree) Leaf Oil
Est. %0.3
Function
Origin
A fragrant and antioxidant essential tea tree oil praised for its antiseptic and antimicrobial properties. Tea tree oil helps to treat acne, inflamed skin, and small wounds. It might, however, cause allergies and skin irritations.
Ethyl Hexanediol
Est. %0.3
Function
Origin
A synthetic solvent used to dissolve difficult ingredients. It also has a pleasant scent and could be used to contribute to product fragrance.
Asiaticoside
Est. %0.3
Function
Origin

A Gotu Kola or Centella Asiatica derivative with confirmed anti-wrinkle efficacy.

Asiatic Acid
