How moisturizing is it?

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.0 out of 10 and a high humectancy of 7.2 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, The INKEY List Polyglutamic Acid Dewy Sunscreen SPF 30 has a zero anti-wrinkle rating.

It contains Camellia Sinensis Leaf Extract, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Camellia Sinensis Leaf Extract 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.

Sun protection

The INKEY List Polyglutamic Acid Dewy Sunscreen SPF 30 has an SPF of 30 and provides high sun protection. This level of protection is ideal for activities such as spending time at the beach, outdoor sports, or other activities involving prolonged sun exposure. It's important to apply sunscreen generously and reapply every two hours or after swimming or sweating to maintain effectiveness.

Ingredients explained

Water
Est. %60
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.
Octocrylene
Est. %9
Function
Origin
OctocryleneA synthetic compound that protects skin against harmful ultraviolet light.
Glycerin
Est. %6
Function
Origin
Glycerin

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

Octisalate
Est. %4
Function
Origin
OctisalateA UVB sunscreen also known as ethylhexyl salicylate. It is normally paired with UVA sunscreens to provide broad-spectrum protection. Octisalate also protects other ingredients, like colorants and antioxidants, from deterioration due to exposure to UV light.
Coco-Caprylate/Caprate
Est. %3
Function
Origin
Coco-Caprylate/CaprateA naturally-derived emollient ester. It is a blend of caprylates and caprates and, relative to other emollients, is lightweight and dry on the skin. As a result, coco-caprylate/caprate serves as a natural alternative to volatile silicones.
Avobenzone
Est. %2.5
Function
Origin
AvobenzoneA popular sunscreen that protects against UVA rays, which cause premature aging and skin cancer. Avobenzone degrades after about 30 minutes of sun exposure and becomes ineffective. It is therefore often paired with UV-filter stabilizers such as octocrylene.

Cetearyl Alcohol
Est. %1
Function
Origin
Cetearyl AlcoholA blend of cetyl alcohol and stearyl alcohol, the fatty alcohols that are derived from palm oil. It helps to create emulsions that give off a soft and silky emollient feel and also increase product thickness.
Glyceryl Stearate SE
Est. %0.3
Function
Origin
Glyceryl Stearate SEAn emulsifier, where the SE stands for self-emulsifying. Emulsions containing glyceryl stearate SE often impart a smooth, velvety feel upon the skin.
Tromethamine
Est. %0.3
Function
Origin
TromethamineAn ingredient based on amino acids that is commonly used as a pH adjuster. It has a high pH, which means that it is basic (alkaline), so adding tromethamine to a skincare product will increase its overall pH level.
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.
Propanediol
Est. %0.3
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.

Sodium Stearoyl Glutamate
Est. %0.3
Function
Origin
Sodium Stearoyl GlutamateA useful ingredient for both cleansing and emulsifying purposes. It is a powerful agent for washing away dirt and oils from the skin.
Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer
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.
Dimethicone
Est. %0.3
Function
Origin
DimethiconeThe 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.
Squalane
Est. %0.3
Function
Origin
SqualaneAn occlusive moisturizing and emollient compound that forms part of the skin’s sebum. The main source of squalane had always been shark liver. Now, however, it is manufactured synthetically or derived from plant oils, such as olive and peanut oil.
Hectorite

Polysorbate 60
Est. %0.3
Function
Origin

Acrylates/C10-30 Alkyl Acrylate Crosspolymer
Est. %0.3
Function
Origin
Acrylates/C10-30 Alkyl Acrylate CrosspolymerA synthetic ingredient that is used to thicken water and alcohol. It results in a more lightweight formula and is commonly found in gel products.
