What changed, and when.

November 11, 2026 — full source review

We went back through every article and checked each factual claim against a source we could fetch and quote. Where we could not, the claim was softened or removed. This was a correction exercise as much as an update: several things this site had stated with confidence turned out to have no source behind them.

Added

• Evidence register: 39 sources, 80 quotes, each one found word for word in its source on November 11, 2026 by a script that re-fetches the source. The register also lists six popular claims we searched for and found no study behind, and the sources we left out because we could not verify them.
• Safety page rewritten from FDA, American Academy of Dermatology, NIH, UK Food Standards Agency and published research: patch testing, storage, arsenic, ice on skin, who should skip it, when to see a clinician.
• Batch calculator and use-by helper.
• A “Sources for this page” list, with a quoted passage for each source, at the foot of every reviewed article and recipe.
• New images with a recorded rights basis, and captions that say what each picture does and doesn't show.

Corrected or removed, by article

Across the site

• Storage times. Removed “3–5 days” and “5–7 days” in the fridge and “1–3 months” in the freezer. We could not find a source for any of them. Replaced with food-safety rules we could verify: chill within 2 hours (FDA); use refrigerated rice water within 48 hours or freeze it (UK Food Standards Agency rule for leftovers); no use-by date for frozen cubes or for fermented batches. Labelled throughout as borrowed rules, not a tested shelf life.
• “Three to four times a week is the dermatology-accepted rhythm.” No source. Replaced with a plainly labelled suggestion and the one sourced limit for icing (no more than once a day).
• Lists of actives “in” rice water (inositol, ferulic acid, allantoin, kojic acid, amino acids). The compounds are documented in rice bran; nobody has measured them in rinse water from white rice. Rewritten to say so. Allantoin removed entirely: we found no source linking it to rice water.
• Week-by-week results timelines. Removed from every article that had one. None had a source.
• “Use organic rice.” Removed. No study supports it. Replaced with: discard the first rinse.
• Dates shown a day early. Article dates were being displayed in the reader's time zone and showed as the previous day in the Americas. Fixed.

Rice water for face

• The 2018 Cosmetics paper was credited to the wrong authors and described as identifying inositol as the main driver of anti-ageing activity. Its authors are Marto and colleagues, and its abstract says no such thing. Corrected.
• Removed the claim that ferulic acid makes skin sun-sensitive. The cited-everywhere study found it increased protection, in a formulated serum.
• Removed the claim that fermented rice water contains kojic acid, and stated pH figures. Not measured in any source we found.
• Removed details of the SK-II origin story we could not verify (a count of yeast strains, a launch year, a price). What remains is quoted and labelled as the brand's story.
• Removed two weak sources (a general health site and a brand page).

Rice water shelf life

• Rewritten. The table of day and month counts is gone, along with the claims that fermented rice water keeps longer, that freezing “locks in peak potency”, that plastic containers leach into it, and that light degrades it. None had a source. The two sources it did cite were a brand blog and an AI-generated article; both removed.
• The description no longer promises “exact numbers”.

Rice water ice cubes guide

• Benefits separated into what the cold does and what the rice water does. Removed “Subtle brightening over 4–8 weeks” and the results timeline.
• Removed the “60 to 90 seconds” application time as a stated rule; no source gives a tested time. Wrapping the cube and keeping it moving are now tied to quoted sources.
• Arsenic section rewritten from sources: rinsing moves some arsenic into the water; skin absorbs dissolved arsenic in small amounts; nobody has measured cosmetic rice water. Removed advice to prefer rice from a particular region.

Fermented vs plain and the fermented recipe

• The verdict is reversed. These pages said fermented was more potent, richer in ferulic and kojic acid, at a skin-friendly pH, and better for brightening. We found no study of home-fermented rice water on skin at all. The research cited was on a commercial yeast filtrate. Both pages now say this, and the recipe carries its warnings first.
• Fermented rice water is no longer suggested for sensitive or rosacea-prone skin.

How to make rice water: 3 methods

• Removed the table matching methods to skin concerns, and the “upgrades” section suggesting added ingredients. Ranking is now explained as simplicity and hygiene, not effectiveness.
• Added: discard the first rinse, with the source; cool boiled rice water quickly, with the source.

Rice water for dark spots

• The short answer used to say rice water, especially fermented, could modestly reduce mild pigmentation over 4–8 weeks. It now says this has not been shown. A 2020 review found only laboratory support. Added what the American Academy of Dermatology recommends, and why spots often fade on their own.
• Removed the spot-type timeline and the instruction to use fermented rice water.

Rice water for keratosis pilaris

• Removed “rice water can help with both exfoliation and moisture” and the results timeline. No study exists. Rebuilt around AAD guidance, with rice water as an optional rinse before moisturiser.
• Product notes no longer state percentages or call any product “the single best”; we have not tested them.

Rice water for rosacea

• Removed “the plain, room-temperature version may actually help” and “what dermatologists say” where no dermatologist was cited. Now quotes the National Rosacea Society, the AAD and NIH directly, including the AAD's advice against toners.
• Removed a blog source.

Under-eye bags

• Removed the claim that rice water adds “a brief barrier of soothing compounds”, the statement that caffeine eye cream extends the effect, and an unsourced results timeline. The effect is now attributed to cold alone, with a hygiene caution about unpreserved liquid near the eyes.
• Corrected a broken link to the American Academy of Ophthalmology.

Yu-Su-Ru history

• Substantially corrected. The one scholarly source we could verify says Heian court ladies “were said to have” used rice rinse water on their hair. Claims about faces, geisha, fermented rice water across three countries, periodic use, and specific compounds were removed as unverified, and are listed on the page.
• A romanised Korean term was wrong and has been corrected. A Japanese-script spelling and translation we could not verify were removed.
• Removed two unreliable sources (a brand blog and an AI-written encyclopedia).

Recipes: soaked and boiled

• Storage notes replaced as above. The boiled recipe said the rice-starch research was “built on this preparation”; it was not, and the page now says what the study actually used.
• “Good for” labels such as “barrier repair” and “brightening” replaced with plain descriptions of what each method is suited to.

Site pages

• How We Source said every method had been “prepared, frozen, and applied by the editorial team”. That was not true and contradicted the rest of the site. Removed. We do not do hands-on testing.
• An unused author-profile file said posts were “medically reviewed by licensed practitioners”. They are not. Removed.
• The footer said “editor-reviewed”. Reworded.
• The newsletter page had a sign-up form that was not connected to anything. Removed until there is a newsletter.

Not reviewed in this pass

• Best rice ferment essences of 2026. We re-checked one brand statement (SK-II's Pitera percentage) and added a summary of the ferment research. The other products' percentages, prices and sizes could not be re-checked and the article says so. It does not carry a “Reviewed” date.

How to tell us we're wrong

Use the contact page. If you can point to a source for something we removed, we'll read it and, if it holds up, add it to the register and restore the claim with the quote.

April 2026 — site launched

The first eleven articles and three recipes were published between April 24 and April 27, 2026.
