We get things wrong sometimes. When we do, we want to fix it quickly.
How to report an error
Use our Contact page or email contact@seoullit.com. Tell us the page, the claim and, if you can, the source that shows the problem.
How we check
We go back to the primary source behind the claim, whether that is the ingredient list, the regulator’s notice, the study or the review we quoted, and compare it with what the page says. If a product has been reformulated, we check which version the page describes.
How we fix it
- Factual errors, such as a wrong UV filter, a misquoted source or a claim the source doesn’t support, are corrected on the page once we have confirmed them.
- If the same mistake appears on other pages, we correct those too.
- If a shopping link does not lead to the product a page discusses, we remove or replace it.
- We keep an internal record of each correction, and a selection of recent ones is listed below with their dates.
Recent corrections
- 10 to 12 October 2026: On 54 posts we removed or reworded sentences, titles and search descriptions that read as if we had used or tested the products ourselves, counted ingredient lists by hand or cross-checked every formula on ingredient databases. We also rewrote passages written in the first person singular on eight posts, since two people run the site. Our reviews are ingredient-label analyses; How Seoullit Works explains the method.
- 10 to 12 October 2026: On 11 posts we removed 18 Korean blog reviews from our sources, along with the quotes and passages that relied on them. Their authors had received the product free, from the brand or through a review campaign, or had put commission-paying shopping links in the review, and in two posts our source list had described such a review as self-purchased. Our no-sting eyes guide also quoted a Korean blog review that readers cannot open because it is private, and we removed that quote and the lines that relied on it. On 29 posts we removed statements about what reviewers generally say, how popular a product is or what most reviews miss that the post’s sources did not support, and we made the same change to three short product notes in our interactive tools.
- 10 to 12 October 2026: Four posts were wrong about bemotrizinol, also called Tinosorb S. Our Anua sunscreen guide listed Tinosorb S among filters that are not FDA-approved, and our comparison of Sephora’s K-Beauty edit called Tinosorb S a different molecule from bemotrizinol. In June 2026 the FDA added bemotrizinol to its sunscreen monograph, as our bemotrizinol buying guide explains. Our post on the FDA decision said Beauty of Joseon Relief Sun contains bemotrizinol, which the product’s ingredient list at two retailers does not show. Our post on whether Korean sunscreens are safe said, in the present tense, that the FDA has cleared only two UV filters as generally recognized as safe and effective; it now says the FDA proposed that status for zinc oxide and titanium dioxide in 2019 and added bemotrizinol in 2026. We corrected all four posts.
- 10 to 12 October 2026: On 13 posts we removed statements that chemical filters leave no white cast or finish clear, including no-white-cast criteria on pick lists that include sunscreens with MBBT (Tinosorb M), a filter that can leave a white cast, as our white cast guide explains. On six posts we corrected ingredient claims: Alcohol-Free and Fragrance-Free tags on posts about products whose ingredient lists include t-butyl alcohol or fragrance ingredients, an alcohol-free claim for a shortlist whose picks include t-butyl alcohol, and statements that Beauty of Joseon Relief Sun contains panthenol and galactomyces, neither of which is on its ingredient list.
- 10 to 12 October 2026: On seven posts, words inside quotation marks did not match the source word for word; we changed them to the source’s wording or removed them. Our post on how much sunscreen stick to apply applied Michelle Wong’s “very ballpark numbers” caveat to her SPF estimates, while she wrote it about her pass counts, and left out her note that the amount applied seemed to depend heavily on pressure. Its FAQ said softer sticks deposit more per swipe, which her write-up does not say, and its search description said we had weighed the sticks; she weighed them. We rewrote those passages to follow her write-up. Our post on whether Korean sunscreens are safe put words in quotation marks that the FDA’s 2019 proposal and the American Academy of Dermatology’s guidance do not use; it now quotes both word for word. One roundup that our best-selling sunscreen comparison cited has gone offline, so we removed the phrases we had quoted from it and say so in the post.
- 10 to 12 October 2026: On eight posts we narrowed titles, descriptions and sentences that claimed to cover a whole product line or set. Our SKIN1004 guide covers four of the brand’s sunscreens and our Tage guide covers five, and we removed the claim that all eight sunscreens in Sephora’s K-Beauty edit use different UV filters from their Korean versions, which our own table leaves unverified for four of them. On 17 posts we corrected statements that contradicted the post’s own table or text, a source it cited or another of our posts, such as how many products appear on both lists in our best-selling sunscreen comparison and a WHO finding that fresh snow almost doubles UV exposure, which one post had shortened to “doubles”. We replaced 11 featured images whose text repeated corrected claims, corrected the alt text of two more, and removed 26 tags from 22 posts that did not cover the tagged topic or said the opposite.
- 7 October 2026: Amazon links on 14 posts went to US-market sunscreens from Purito, Round Lab, Beauty of Joseon and Goodal whose formulas differ from the Korean products the posts describe. On two more posts, a link went to a SKIN1004 Air-Fit Suncream Plus listing we could not match to the ingredient list cited in those posts. We removed the links from all 16 posts.
- 3 October 2026: Two posts listed UV filters incompletely. Our reef-safe sunscreen post listed three filters for the Korean SKIN1004 Water-Fit Sun Serum instead of four, and our guide for deep skin tones left Polysilicone-15 out of its list for Tocobo Bio Watery Sun Cream. We corrected both posts.
- 3 October 2026: On 43 posts, Amazon links led either to US-market SKIN1004, Tocobo and Anua sunscreens whose UV filters differ from the Korean products the posts describe, or to Amazon searches whose results did not clearly include the product we wrote about. We removed those links.
- 2 October 2026: We updated 27 posts that described Beauty of Joseon Relief Sun or Round Lab Birch Juice Moisturizing Sun Cream. Most of them had used ingredient lists that differ from the current ones: Relief Sun no longer lists rice extract second at 30%, and the current Korean Round Lab list has four UV filters where some posts named two.
- 29 September 2026: Our post on sun sticks over makeup said the Dr.G Green Mild Up Sun Stick is fragrance-free and contains houttuynia. Its ingredient list ends with fragrance and has no houttuynia. We corrected the post and its FAQ, and added a note to our no-sting eyes guide that its Round Lab pick, which lists no fragrance, does list chamomile flower oil.
- 28 September 2026: A quotation from BASF’s Tinosorb M technical sheet on our Tinosorb S vs M page read “UVA-we range” where BASF wrote “UVA-I range”. We restored the original wording.
- 28 September 2026: Our guide to bemotrizinol sunscreens in the US had several errors. Among them were Ultra Violette Unblock Screen’s percentages and active ingredients, and a claim that L’Oreal had sold an older Kiehl’s formula in the US, which its export-only label does not support. We corrected them, added a dated correction note at the top of the page and replaced the title “Every Bemotrizinol Sunscreen You Can Buy in the US Right Now (2026)”.
