What the product description says

“Hada Labo Gokujyun Premium Hyaluronic Acid Hydrating Cream 2020 Edition”

From product name

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: arginine, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: arginine, butyrospermum parkii butter.

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.5–0.75%

Hyaluronic acidKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin. Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation~0.25–0.5%

Hydrolyzed hyaluronic acidKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. A version of it is naturally present in skin~0.3–0.55%

Phytosteryl macadamiateKey active· EmollientEffect: HighHelps soften the upper layer of the skin~0.25–0.5%

ArginineKey active· Humectant, OcclusiveEffect: HighAn amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin~0.2–0.4%

Butyrospermum parkii butterKey active· Emollient, OcclusiveEffect: HighA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~3.2–3.9%

DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~0.25–0.5%

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~1.6–2%

Olea europaea fruit oilKey active· EmollientEffect: MediumAn emollient that helps soften the skin but is not effective for restoring its barrier function. Might be helpful to calm down inflammation~0.25–0.5%

Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~6.1–7.4%

Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.25–0.5%

Lactic acidUnder-dosedEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.4–0.6%
