Does Haruharu Wonder Black Rice Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Haruharu Wonder Black Rice Serum:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.0 out of 10.
  • Antioxidant protection.

Lightweight moisturizer ideal for oily skin and a humectant boost for any skincare routine

According to CreamScan analysis, Haruharu Wonder Black Rice Serum 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 Propanediol (est. ≈6.0%), Aloe Barbadensis Leaf Extract (est. ≈3.0%) and Betaine (est. ≈2.0%).

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.

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 Haruharu Wonder Black Rice Serum is rich (> 3%) in antioxidants, specifically Aloe Barbadensis Leaf Extract (est. ≈3.0%).

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.

Ingredients explained

Water
Est. %75
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.
Propanediol
Est. %6
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.
Oryza Sativa (Rice) Extract
Est. %4
Function
Origin
Oryza Sativa (Rice) ExtractAn abrasive rice extract rich in various emollient fatty acids, amino acids, and vitamin E.
Aloe Barbadensis Leaf Extract
Est. %3
Function
Origin
Aloe Barbadensis Leaf ExtractDerived from Aloe vera leaves, this moisturizing humectant, soothing, and antioxidant extract is commonly used in products targeting eczema, sunburn, or dermatitis. It soothes the skin and reduces the signs of inflammation and sensitivity.
Betaine
Est. %2
Function
Origin
BetaineAn 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.
Glycerin
Est. %1.5
Function
Origin
Glycerin

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

Xanthan Gum
Est. %1.3
Function
Origin
Xanthan GumA natural multi-functional ingredient that originates from fermented sugars. Xanthan gum acts as a viscosity-building agent to thicken skincare products. It is also an excellent stabilizer and works well to hold other ingredients together.
Ceramide AP
Est. %0.3
Function
Origin
Ceramide APPreviously called Ceramide 6 II, Ceramide AP is one of the most common ceramides in the skin. Research has shown that dry, flaky skin has significantly less Ceramide AP. Its application helps to treat dry skin by restoring balance in the skin lipids.
1,2-Hexanediol
Est. %0.3
Function
Origin
1,2-HexanediolA multi-functional formula helper. It is a well-studied preservtive against bacteria and can help pigments and fragrances disperse evenly in a formula.
Phyllostachys Pubescens Shoot Bark Extract
Est. %0.3
Function
Origin
Phyllostachys Pubescens Shoot Bark Extract
Aspergillus Ferment
Est. %0.3
Function
Origin
Aspergillus Ferment
Butylene Glycol
Est. %0.3
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.

Yeast Beta-Glucan
Est. %0.3
Function
Origin
Yeast Beta-Glucan
Trehalose
Est. %0.3
Function
Origin
TrehaloseA sweet-tasting saccharide that can be found in various yeasts and fungi and that is manufactured from starch for cosmetic purposes. It is one of the most popular sugars in skincare and is mainly used for its humectant properties.
Zanthoxylum Piperitum Fruit Extract
Est. %0.3
Function
Origin
Zanthoxylum Piperitum Fruit ExtractA pepper extract that is claimed to have antibacterial and antioxidant properties.
Pulsatilla Koreana Extract
Est. %0.3
Function
Origin
Pulsatilla Koreana ExtractAn extract derived from the Korean pasque flower. It contains various saponins with antimicrobial properties and has been successfully tested against bacteria involved with acne.
Usnea Barbata (Lichen) Extract
Est. %0.3
Function
Origin
Usnea Barbata (Lichen) ExtractA lichen-derivative with proven antibacterial activity.
Alcohol
Est. %0.3
Function
Origin
AlcoholAn 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.
Sodium Phytate
Est. %0.3
Function
Origin
Sodium PhytateSodium phytate is a chelating agent that serves to remove heavy metal ions from water. Removing metal ions helps other ingredients, such as antioxidants and preservatives, to perform better and keep products from separating.
Hyaluronic Acid
Est. %0.3
Function
Origin
Hyaluronic Acid

A potent, skin-identical humectant moisturizing ingredient that is able to bind water 1000 times its own weight. The anti-aging benefits of hyaluronic acid are due to its ability to stimulate the synthesis of collagen in the skin.

Polyglyceryl-10 Laurate
Est. %0.3
Function
Origin
Polyglyceryl-10 LaurateA vegetable glycerin or synthetically produced emulsifier and gentle cleansing agent. It won't leave skin feeling tight or dry when used to cleanse.
Polyglyceryl-10 Myristate
Est. %0.3
Function
Origin
Polyglyceryl-10 MyristateA solubilizer that can help incorporate small amounts of oil to an otherwise watery product while providing lightweight skin feel.
Lavandula Angustifolia (Lavender) Oil
Est. %0.3
Function
Origin
Lavandula Angustifolia (Lavender) OilAn essential oil derived from common, or true, lavender. It is used in skincare for its lovely, calming scent. Like all essential oils, however, it may cause a contact skin allergy in more sensitive individuals.
