Shirojyun Premium Whitening Emulsion
Shirojyun Premium Whitening Emulsion
Product Description
Product overview
A serum-level brightening emulsion from Hada Labo, the pharmacy-born J-beauty line by Rohto. It pairs medicated White Tranexamic Acid with anti-inflammatory licorice derivative, a sting-free Vitamin C, Vitamin E and dual-weight hyaluronic acid to fade dark spots and even skin tone while sealing in deep, lasting hydration — all in a fragrance-free, alcohol-free formula.
Fades & Prevents Dark Spots
Medicated White Tranexamic Acid interrupts melanin signaling to lighten existing spots and stop new pigmentation forming after UV stress.
Texture & feel
SENSORYFades & Prevents Dark Spots
Medicated White Tranexamic Acid interrupts melanin signaling to lighten existing spots and stop new pigmentation forming after UV stress.
Dual-Weight Hyaluronic Acid
Nano hydrolyzed HA reaches deeper layers while sodium hyaluronate holds water at the surface for plump, lasting hydration.
Sting-Free Vitamin C
Stable Magnesium Ascorbyl Phosphate brightens and adds antioxidant defense without the irritation of pure ascorbic acid.
Soothes & Calms
Glycyrrhizic acid (licorice-derived) is an anti-inflammatory active that helps reduce redness and post-UV irritation.
Serum-Level, Lightweight
A milky emulsion that seals actives and moisture into the skin without feeling heavy, greasy or occlusive.
Pharmacy-Grade Value
A Japanese quasi-drug (medicated) formula at drugstore pricing — multi-active sophistication for a fraction of Western brighteners.
Safety & compatibility
SAFEContains topical tranexamic acid, which dermatologists keep on a "watch" rather than "avoid" list. Likely low-risk topically, but consult your OB/GYN before use.
Not fungal-acne safe. Meadowfoam seed oil, glyceryl stearate and other fatty esters can feed malassezia.
Fragrance-free, dye-free and alcohol-free with a weakly acidic pH. Patch test advised due to sodium bisulfite and phenethyl alcohol.
Pairs well with niacinamide, peptides, HA and sunscreen. If sensitive, separate from strong AHA/BHA or retinol (alternate AM/PM).
Low (rated ~1/5). Ingredient analyses detect no high-comedogenic oils, so pore-clogging risk is minimal for most users.
A brightening product is only as effective as your SPF. Always finish daytime routines with broad-spectrum sunscreen.
Ingredient breakdown
INGREDIENTSTranexamic Acid ~2% (Active)Proven
The medicated whitening active and reason this product is classed as a quasi-drug in Japan. It calms the UV-triggered cascade that tells pigment cells to overproduce melanin, fading dark spots and preventing new ones.
- Mechanism: Inhibits the plasmin/plasminogen pathway, reducing melanocyte activation and melanin transfer.
- Clinical use: Widely studied for melasma and post-inflammatory hyperpigmentation, valued for being gentle versus hydroquinone.
Glycyrrhizic Acid (Dipotassium Glycyrrhizate) ActiveProven
A licorice-root derivative and the formula's second medicated active. It is a well-documented anti-inflammatory that soothes redness and irritation, supporting the brightening actives by keeping skin calm.
- Source: Derived from licorice (Glycyrrhiza) root; glycyrrhizin has recognised anti-inflammatory activity.
- Benefit: Reduces UV-induced inflammation, which itself drives pigmentation.
Magnesium Ascorbyl Phosphate Vitamin CProven
A stable, water-soluble Vitamin C derivative (MAP) that brightens and protects without the sting or instability of pure ascorbic acid — ideal for daily and sensitive-skin use.
- Function: Skin-brightening antioxidant; helps inhibit tyrosinase and neutralise free radicals.
- Advantage: Far more stable than L-ascorbic acid and gentle at the levels used here.
Tocopherol (Vitamin E) ~3.5–5.3%Proven
Pure Vitamin E at a meaningful concentration. It moisturises, supports the skin barrier and works synergistically with Vitamin C for stronger antioxidant defense against UV-driven damage.
- Analysis: Independent formulation review estimates tocopherol at roughly 3.5–5.3% in this product.
- Function: Antioxidant, anti-aging, anti-inflammatory and moisturising.
Hydrolyzed Hyaluronic Acid (Nano) HumectantProven
A low-molecular-weight, nano-sized hyaluronic acid that penetrates beyond the surface to hydrate deeper layers and help carry actives into UV-stressed skin.
- Benefit: Smaller fragments reach deeper than standard HA for fuller, longer-lasting hydration.
Sodium Hyaluronate HumectantProven
The salt form of hyaluronic acid that draws and binds water at the skin's surface, working alongside the nano HA for layered, multi-depth moisture.
- Capacity: Holds many times its weight in water, leaving skin plump and supple.
Glycerin & Diglycerin HumectantsProven
Two of skincare's most reliable humectants. They pull moisture into the skin and keep the emulsion comfortable and non-tight, complementing the hyaluronic acids.
- Role: Core hydrators that improve softness and reduce trans-epidermal water loss.
Dipropylene Glycol & Butylene Glycol Solvent / HumectantPromising
Lightweight glycols that dissolve the actives, keep the texture fluid and add a touch of extra hydration — they help give the emulsion its fast-absorbing, non-greasy feel.
- Function: Carry actives evenly across skin and improve overall product spreadability.
Limnanthes Alba (Meadowfoam) Seed Oil EmollientPromising
A lightweight, highly stable plant oil that softens skin and reinforces the moisture barrier without a heavy feel — part of what gives the emulsion its dewy finish.
- Profile: Low comedogenic rating (~1); rich in long-chain fatty acids that resist oxidation.
Dimethicone & Octyldodecanol EmollientsPromising
Texture and barrier helpers. Dimethicone is a non-comedogenic silicone that smooths and seals moisture, while octyldodecanol is a heavy fatty alcohol that improves slip and locks in hydration.
- Octyldodecanol: High molecular weight, so it conditions the surface rather than absorbing in.
- Dimethicone: Forms a breathable, smoothing film that reduces water loss.
Sodium Stearoyl Glutamate & Glyceryl Stearate EmulsifiersPromising
The gentle, amino-acid-based emulsifying system that lets the watery and oily phases blend into a stable, silky emulsion and stay that way over the life of the product.
- Sodium Stearoyl Glutamate: A mild, hypoallergenic amino-acid emulsifier.
- Carbomer & Xanthan Gum: Thicken and stabilise the texture for a uniform feel.

Where it fits in your routine
ROUTINEApply after your watery lotion/toner and any treatment serums. As a milky emulsion, it is your moisture-sealing brightening step — follow with cream at night and broad-spectrum sunscreen every morning.
How to use
HOW TO USEPrep
After cleansing and applying your Hada Labo lotion/toner, dispense a coin-sized amount (about 2 pumps) into your palm.
Warm
Gently rub between your palms to warm the emulsion, which helps it spread and absorb more evenly.
Press In
Press over the whole face from the centre outward, focusing on areas with dark spots. Avoid tugging the skin.
Seal & Protect
Follow with a cream at night to lock everything in. In the morning, always finish with sunscreen to protect your progress.

- Gentle and fragrance-free — no sting from the Vitamin C
- Outstanding value for medicated (quasi-drug) actives

- Tranexamic acid means caution during pregnancy
- 140ml can deplete quickly with daily use
- Limited availability outside Asian retailers

Budget-friendly alternatives (dupes)
DUPESThe same brand's non-premium version. Keeps the tranexamic acid + hyaluronic acid core but drops the boosted Vitamin C/E and luxe texture of the Premium line.
Another J-beauty brightener, focused on Vitamin C. Great for radiance but lighter on hyaluronic hydration and without tranexamic acid.
A niacinamide-based brightening moisturizer with a broader active list, but a thicker cream texture and added fragrance — less suited to sensitive skin.

Frequently asked questions
FAQIt contains topical tranexamic acid, which many dermatologists keep on a "watch" rather than an "avoid" list. There is no strong evidence that it is harmful topically, but because it is a medicated active, you should check with your OB/GYN before using it during pregnancy or nursing.
No. It contains meadowfoam seed oil, glyceryl stearate, glyceryl heptanoate and other fatty esters that can feed malassezia. If you are prone to fungal acne, choose a fungal-acne-safe brightener instead.
Yes, generally. It already includes a gentle Vitamin C (Magnesium Ascorbyl Phosphate), and layering with niacinamide, hyaluronic acid or peptides is fine. With retinol or strong AHA/BHA, alternate AM/PM or buffer between steps to avoid irritation, especially if your skin is sensitive.
It is best for normal, dry and combination skin that wants brightening plus hydration. Oily skin can use it in a thin layer, while those with fungal-acne-prone skin should be cautious because it is not malassezia-safe.
Hydration is immediate. Brightening usually becomes visible within 2–4 weeks, with dark-spot fading typically appearing around 6–8 weeks of consistent daily use combined with sunscreen.
As an emulsion (milk), apply it after your watery lotion/toner and any treatment serums, but before cream and sunscreen. It acts as your moisture-sealing brightening step.
The risk is low. It rates around 1/5 and ingredient analyses detect no high-comedogenic oils, although it is not fungal-acne safe. Most users find it does not clog pores.
Use it within about 12 months of opening. Unopened, Japanese quasi-drug emulsions generally keep for roughly 3 years. Store it cool and dry with the cap closed to preserve the actives.
Verdict: A standout pharmacy-grade brightener. Hada Labo's Shirojyun Premium Whitening Emulsion delivers a sophisticated multi-active approach — medicated tranexamic acid, soothing licorice, stable Vitamin C, Vitamin E and dual hyaluronic acid — at a price that undercuts almost every Western competitor. It loses half a star only for not being fungal-acne safe and for the pregnancy caution around tranexamic acid. For anyone with dry-to-combination skin chasing brighter, more even tone alongside serious hydration, it is an easy recommendation.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
