Key Benefits of Hada Labo Koi-Gokujyun Perfect Gel

 
These are the key benefits you can expect from using Hada Labo Koi-Gokujyun Perfect Gel:
 

Lightweight Moisturizer Perfect for Combination and Oily Skin

According to CreamScan analysis, Hada Labo Koi-Gokujyun Perfect Gel is highly moisturizing, with a moisturizing rating of 6.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.2 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Butylene Glycol (est. ≈7.5%), Hydroxyethyl Urea (est. ≈5.0%) and Glycerin (est. ≈3.0%).

This type of moisturizer is ideal for people with combination and oily skin who want maximum hydration in a relatively lightweight, non-greasy formula. It combines a significant amount of humectants with a limited amount of occlusive ingredients to boost moisturizing efficacy without feeling too heavy.

This product may also be a good choice for people with normal skin who prefer fast-absorbing textures, as it balances significant moisturizing potential with a relatively lightweight texture.

A Humectant Boost for Any Skincare Routine

But it’s not limited to combination and 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.

Ingredients explained

Water
Est. %70
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. %7.5
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.

Hydroxyethyl Urea
Est. %5
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.
Glycerin
Est. %3
Function
Origin
Glycerin

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

Pentylene Glycol
Est. %2.5
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.

Squalane
Est. %2
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.
Triethylhexanoin
Est. %1.5
Function
Origin
TriethylhexanoinAn occlusive and emollient ester of glycerin and a fatty acid. It is easily spreadable and does not leave a sticky after-feel.
Ammonium Polyacryloyldimethyl Taurate
Est. %1.3
Function
Origin
Ammonium Polyacryloyldimethyl TaurateAn emulsion stabilizer and thickener with gelling properties. The products containing this ingredient frequently feature lightweight and refreshing aesthetics upon application to the skin.
Dimethicone
Est. %1
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.
PPG-17-Buteth-17
Est. %0.3
Function
Origin
PPG-17-Buteth-17
Triethyl Citrate
Est. %0.3
Function
Origin
Triethyl Citrate
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.
Disodium Succinate
Est. %0.3
Function
Origin
Disodium Succinate
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.

Agar
Est. %0.3
Function
Origin
AgarA multifunctional jelly derived from red algae that can thicken water-based products.
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.
Succinic Acid
Est. %0.3
Function
Origin
Succinic Acid
Sodium Acetylated Hyaluronate
Est. %0.3
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.
Arginine
Est. %0.3
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.
Hydrolyzed Hyaluronic Acid
Est. %0.3
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.
Hydrolyzed Collagen
Est. %0.3
Function
Origin
Hydrolyzed Collagen

A humectant, film-forming, and emollient mixture of various proteins and peptides that were created by cutting the huge molecules of normal collagen into smaller pieces for better absorption. It also has some antioxidant properties.

Dextrin
