Key Benefits of Hada Labo Gokujun Premium Hyaluronic Solution

 
These are the key benefits you can expect from using Hada Labo Gokujun Premium Hyaluronic Solution:
 

Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, Hada Labo Gokujun Premium Hyaluronic Solution is quite moisturizing, with 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. ≈9.0%), Glycerin (est. ≈6.0%) and Hydroxyethyl Urea (est. ≈3.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

Tip: Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

A Humectant Boost for Any Skincare Routine

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

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

Rich in Skin-Protecting Antioxidants

We estimate that Hada Labo Gokujun Premium Hyaluronic Solution is rich (> 3%) in antioxidants, specifically Sodium Hyaluronate (est. ≈2.0%).

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 AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Hada Labo Gokujun Premium Hyaluronic Solution

 
CreamScan AI identified a few things to consider before adding Hada Labo Gokujun Premium Hyaluronic Solution to your skincare routine:
 

If It’s Your Only Moisturizer, It Needs to Be Paired with Some Occlusives

While humectants are highly effective at attracting water to the skin, studies (J. N. Kraft, C. W. Lynde) suggest they may not be efficient when used alone.

One major drawback of purely humectant moisturization is that the water attracted by humectants to the upper layers of the skin can evaporate completely into the environment through transepidermal water loss (TEWL). Adding occlusive ingredients helps seal this moisture into the skin and prevent further water loss.

If you’re using Hada Labo Gokujun Premium Hyaluronic Solution as your only moisturizer, consider pairing it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones. These work alongside humectants to create a protective barrier, locking in hydration and ensuring longer-lasting moisturization. The amount of occlusive needed depends on your skin type - the drier the skin, the more occlusives it requires.

If this product is used not as a standalone moisturizer but as part of your skincare routine, such as a toner or serum, it should be applied before your main moisturizer (unless it's a sunscreen), which will provide the necessary occlusivity on top of it.

Ingredients explained

Water
Est. %65
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.
Butylene Glycol
Est. %9
Function
Origin
Butylene Glycol

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.

Glycerin
Est. %6
Function
Origin
Glycerin

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

PPG-10 Methyl Glucose Ether
Est. %4
Function
Origin
PPG-10 Methyl Glucose Ether
Hydroxyethyl Urea
Est. %3
Function
Origin
Hydroxyethyl UreaHydroxyethyl urea is a synthetic derivative of regular urea (read about it here). This ingredient, similarly to urea, is humectant moisturizing and helps to retain more water to the skin’s surface, leaving it more moisturized. There aren't any studies that analyze the effects of this ingredient in great detail.
Sodium Acetylated Hyaluronate
Est. %2.5
Function
Origin
Sodium Acetylated HyaluronateA chemically modified version of hyaluronic acid. It is more stable and less sticky than regular HA, while still providing the same humectant moisturizing properties (according to the manufacturer). There have been no clinical studies to confirm this.
Sodium Hyaluronate
Est. %2
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.

Hydrolyzed Hyaluronic Acid
Est. %1.5
Function
Origin
Hydrolyzed Hyaluronic AcidA smaller-molecule version of the regular hyaluronic acid. It is a powerful humectant that absorbs into the skin and offers moisturizing, smoothing, and anti-wrinkle effects. It is also slightly anti-inflammatory and displays subtle antioxidant properties.
Hydroxypropyltrimonium Hyaluronate
Est. %1.3
Function
Origin
Hydroxypropyltrimonium Hyaluronate
Sodium Hyaluronate Crosspolymer
Est. %1
Function
Origin
Sodium Hyaluronate CrosspolymerA modified version of regular hyaluronic acid. It attracts large volumes of water, thereby making it an effective humectant moisturizing ingredient.
Aphanothece Sacrum Polysaccharide
Est. %0.3
Function
Origin
Aphanothece Sacrum Polysaccharide
Hydrogenated Starch Hydrolysate
Est. %0.3
Function
Origin
Hydrogenated Starch HydrolysateA starch-based syrup that binds to water and helps to form a film on the skin’s surface.
Glycosyl Trehalose
Est. %0.3
Function
Origin
Glycosyl Trehalose
Diglycerin
Est. %0.3
Function
Origin
DiglycerinA powerful humectant that collects moisture, making skin feel hydrated and supple. Diglycerin is less sticky and a stronger humectant, but slower absorbing than standard glycerin.
Sorbitol
Est. %0.3
Function
Origin
SorbitolA sweet-tasting alcohol derived from glucose. Aside from its sweet taste (for which it is used as a very common sweetener), Sorbitol is also very good at retaining water and is used in skincare as a humectant.
Pentylene Glycol
Est. %0.3
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.

Triethyl Citrate
Est. %0.3
Function
Origin
Triethyl Citrate
Carbomer
Est. %0.3
Function
Origin
CarbomerA synthetic ingredient with the ability to gel water. When used in emulsions, such as lotions and creams, carbomer can also act as an emulsion stabilizer.
Polyquaternium-51
Est. %0.3
Function
Origin
Polyquaternium-51A biocompatible phospholipid copolymer that is designed to mimic the lipid-based cell membrane found in human skin. Its main function is as a humectant moisturizer.
PEG-32
Est. %0.3

Disodium EDTA
Est. %0.3
Function
Origin
Disodium EDTAA synthetic chelator that helps to maintain the look and smell of a product by 'locking up' troublesome metal ions.
Potassium Hydroxide
Est. %0.3
Function
Origin
Potassium HydroxideA very alkaline ingredient, meaning that it has a high pH. Potassium hydroxide is therefore useful in bringing a low pH in a cosmetic product up to a more neutral, skin-safe level.
Diethoxyethyl Succinate
Est. %0.3
Function
Origin
Diethoxyethyl Succinate
Disodium Succinate
Est. %0.3
Function

Disodium Succinate
Succinic Acid
Est. %0.3
Function
Origin
Succinic Acid
Phenoxyethanol
Est. %0.3
Function
Origin
PhenoxyethanolThe most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Methylparaben
Est. %0.3
Function
Origin
MethylparabenA preservative that keeps a product unspoiled. There has been a lot of controversy surrounding parabens, although the concentrations found in cosmetic formulations are generally considered to be safe.
