COSRX Ultra-Light Invisible Review: Four Filters, No Mineral

Affiliate links below, but they cost you nothing extra. We only point you to what the ingredient lists actually back up.

The word on the front of this bottle is a claim about the filters, not about the texture. Read the ingredient list and you can see exactly which decision the word is describing.

Four filters, and not one of them is a mineral

Here’s the list COSRX publishes, filtered down to what does the sun protection.

Position	Ingredient as printed	Also called
5	Drometrizole Trisiloxane	Mexoryl XL
6	Ethylhexyl Triazone	Uvinul T 150, Octyltriazone
8	Diethylamino Hydroxybenzoyl Hexyl Benzoate	Uvinul A Plus, DHHB
9	Terephthalylidene Dicamphor Sulfonic Acid	Ecamsule, Mexoryl SX

Those four are the only ingredients the database tags as a sunscreen filter, and the alternative names in the third column are the ones the database prints on its own ingredient pages.^[1][5] We aren’t inventing the equivalence.

Everything between them is the base rather than the protection. Aloe barbadensis leaf water is first, diethylhexyl succinate second, propanediol third, and plain water is only fourth.^[2][3] Niacinamide is seventh, printed between two of the filters.^[2] Witch hazel leaf water turns up at fourteenth.^[2]

What isn’t anywhere on the 28: titanium dioxide, zinc oxide, or a pigment.^[1][2] If you want the mechanism behind why that matters for how a sunscreen looks, our white cast guide takes it apart properly, and we won’t rebuild that argument here. The filter families themselves are laid out in our guide to Korean sunscreen filters.

What am I giving up when there’s no mineral filter?

A fallback. That’s the trade, stated plainly.

Plenty of people go looking for a mineral sunscreen for a specific reason, usually because chemical filters have gone badly for them before. This bottle has no mineral component at all, so it can’t half-meet you. It’s four organic filters or nothing.^[1] That’s a fine deal if newer chemical filters suit you and a bad one if they don’t, and no ingredient list can tell you which of those you are.

The second thing you give up is easy access, at least going by what the brand prints. COSRX’s global store lists this product at $16.00 for 50mL and marks it Sold Out, with the line “Not available at COSRX.COM” on the page.^[3] The same page’s best-seller badge carries a footnote naming two specific stores and two specific windows: “#1 Best Seller on Amazon in Facial Sunscreen (UK: 13 April – 13 May 2026, DE: 8 May – 19 May 2026)”.^[3] That’s the brand’s claim with the brand’s own boundaries on it, and we’re leaving both attached. Why the same Korean formula shows up differently depending on which market you’re shopping in is the subject of our piece on US versions of Korean sunscreens.

Third, and this one is small but worth knowing: the ingredient database flags this page as alcohol-free and as fragrance and essential oil free.^[1] That means someone tagged the page, and nothing beyond it. It isn’t a test result, and we checked the tags by reading them instead of running a search.

Which list does this COSRX Ultra-Light Invisible review read?

The 28-ingredient one, because that’s the one the brand’s own label matches.

Search this product name on INCIDecoder and three separate entries come back, uploaded by three different people. Their ingredient rows count 27, 28 and 29. Picking one at random is how a review ends up describing a list that doesn’t exist.

Entry title as printed	Page date	Rows	Filters it shows
Ultra Light Invisible Sunscreen SPF 50 PA++++	2024-05-07	28	4
Ultra-light Invisible Sunscreen SPF50	2024-05-21	29	3
Ultra Light Invisible Sunscreen	2024-07-21	27	4

Line the three up row by row and the ingredients turn out to be the same. The counts differ because of typing, not reformulation.^[1]

One note on how we count, because it moves the answer by one. We count a single ingredient per row of the page. 1,2-Hexanediol is one ingredient whose own name contains a comma, so chopping any of these lists at every comma hands you one more entry than the page actually lists. The same trap is in the Korean disclosure.^[1][2]

• The 29. A stray comma splits Drometrizole Trisiloxane into “Drometrizole” and “Trisiloxane” across two rows. The page then can’t recognize it, so that entry lists only three filters and Mexoryl XL vanishes from it entirely.^[1]
• The 27. The first ingredient, aloe barbadensis leaf water, is missing. Everything after it matches. That’s why you’ll see this product written up with niacinamide sixth on the list: on that entry it is sixth, and on the label COSRX publishes it’s seventh.^[1][2]
• The 28. Matches the Korean legal ingredient disclosure and the brand’s English list position for position, all 28 of them.^[2][3]

One more thing to keep straight while you’re searching. COSRX sells other sunscreens with similar-sounding names, and the Aloe Soothing Sun Cream is a different formula with an older set of filters. We went through that one in our piece on Korean sunscreen dupes. Same brand, different product.

The Korean box and the global store print different SPF numbers

They do, and the ingredient lists behind them are identical.

Where	Name as printed	Rating as printed
W Concept (Korea)	울트라 라이트 인비저블 선스크린	SPF 50+ PA++++
AMOREMALL, Musinsa (Korea)	울트라 라이트 인비저블 선세럼	SPF50+ PA++++
COSRX global store	Ultra-Light Invisible Sunscreen	SPF50 PA++++

Two differences in one table. The Korean listings print a plus sign after 50 and the brand’s global page doesn’t.^[2][3][4] And the Korean retailers have quietly split on the product’s own name, some selling it as a 선스크린 and some as a 선세럼, while the July 2024 Korean launch coverage used 선스크린.^[4][6]

We can’t tell you from listings alone which number is embossed on the tube that arrives at your door. What we can tell you is that the 28 ingredients behind all three rows above are the same 28, in the same order.^[2][3] How Korea decides what may be printed on a sunscreen box is covered in our piece on Korean SPF labels.

Am I getting what the Korean label is registered for?

The Korean listing registers this product for three things, not one.

The mandatory product disclosure reads “자외선차단 / 미백 / 주름개선 기능성”, which is UV protection, brightening and wrinkle care.^[2] In Korea those are regulatory categories a company files for, so treat the line as a registration rather than as a promise about your face. The same disclosure names Amorepacific as the manufacturer and COSRX as the responsible seller, at 50mL, list price 15,000 won.^[2]

The brand’s own claims, kept separate from ours because they’re the brand’s: Korean launch coverage in July 2024 quotes a content figure of 66.4% witch hazel and aloe extract, and the global page describes niacinamide as preventing UV-induced pigmentation and controlling sebum.^[3][6] Neither is our finding, and neither is something an ingredient list can confirm or deny.

We haven’t worn this, so we’re not going to tell you how it feels. We also went looking for first-hand Korean reviews of this bottle and came away with none we were willing to quote, so there is no wear report anywhere in this piece. What’s left is the label, and the label answers one question on its own: if you want a short list with no mineral filter in it, this is the one to look at, and you can check the current price for the 50mL bottle.

For where these four filters stand next to what European pharmacy brands use, we compared the two label cultures directly in our Korean versus European sunscreen piece.

FAQ

How many ingredients am I actually buying here?

28. That’s the count on the Korean legal ingredient disclosure and on the list COSRX publishes on its own global store, and the two match position for position. If you find a database entry showing 27 or 29, it’s the same formula with a typing error: the 27 drops aloe barbadensis leaf water from the top, and the 29 splits one filter name into two rows.

Is there any mineral filter in this at all?

No titanium dioxide and no zinc oxide appear on the list. The four ingredients tagged as UV filters are drometrizole trisiloxane, ethylhexyl triazone, diethylamino hydroxybenzoyl hexyl benzoate and terephthalylidene dicamphor sulfonic acid, all of them organic filters.

Am I really getting Mexoryl in a Korean sunscreen?

Two of them, going by the names the ingredient database prints on its own pages: drometrizole trisiloxane is also called Mexoryl XL, and terephthalylidene dicamphor sulfonic acid is also called ecamsule or Mexoryl SX. Both appear near the top of this list.

Why does the SPF number look different depending on where I shop?

Because the listings print different things. Korean retailers show SPF 50+ PA++++, and COSRX’s global store shows SPF50 PA++++. The ingredient lists behind both are identical, and a listing can’t tell you what’s embossed on the tube you’ll receive.

Should I pick this if chemical filters have irritated me before?

Be careful. There’s no mineral component in this formula to fall back on, so every bit of the sun protection comes from the four organic filters above. The database does tag the page alcohol-free and fragrance and essential oil free, but a tag on a page is not a patch test on your skin.

Ingredient lists (INCIDecoder, every entry under this product name opened and counted by hand, 2026-07-29):
[1] Searching this product name returns three entries uploaded by three different people. The entry we argue from here is “COSRX Ultra Light Invisible Sunscreen SPF 50 PA++++” (page date 2024-05-07, 28 ingredient rows, four ingredients tagged Sunscreen: Drometrizole Trisiloxane, Ethylhexyl Triazone, Diethylamino Hydroxybenzoyl Hexyl Benzoate, Terephthalylidene Dicamphor Sulfonic Acid; tags on the page, checked by reading them rather than by search, are “#alcohol-free” and “#fragrance & essentialoil-free”; no titanium dioxide, zinc oxide or colorant printed on the list): link. The other two: “COSRX Ultra-light Invisible Sunscreen SPF50” (2024-05-21, 29 rows because a comma splits Drometrizole Trisiloxane across rows 5 and 6, which is why that page lists only three sunscreen filters): link; “COSRX Ultra Light Invisible Sunscreen” (2024-07-21, 27 rows, missing Aloe Barbadensis Leaf Water at position 1, which shifts Niacinamide to sixth): link. How these were counted: one ingredient per row of each page’s ingredient table, cross-checked against the number of ingredient links the same page prints. 1,2-Hexanediol carries a comma inside its own name, so splitting the three lists at every comma instead returns 29, 30 and 28, one too many in every case.

Korean legal ingredient disclosure and product registration (opened in full; Korean, so use browser translation):
[2] W Concept product listing, read 2026-07-29, “울트라 라이트 인비저블 선스크린 50ml [SPF 50+ PA++++]”, list price 15,000 won. The mandatory disclosure headed “화장품법에 따라 기재ㆍ표시하여야 하는 모든 성분” prints all 28 ingredients in order: 알로에베라잎수, 다이에틸헥실석시네이트, 프로판다이올, 정제수, 드로메트리졸트리실록산, 에칠헥실트리아존, 나이아신아마이드, 디에칠아미노하이드록시벤조일헥실벤조에이트, 테레프탈릴리덴디캠퍼설포닉애씨드, 1,2-헥산다이올, 베헤닐알코올, 메틸트라이메티콘, 소듐폴리아크릴로일다이메틸타우레이트, 버지니아풍년화잎수, 트로메타민, 폴리아크릴레이트크로스폴리머-6, 아라키딜알코올, 카프릴릴글라이콜, 에틸헥실글리세린, 아라키딜글루코사이드, 소듐메타포스페이트, 아데노신, 토코페롤, 소듐하이알루로네이트, 알란토인, 시트릭애씨드, 소듐벤조에이트, 포타슘솔베이트.

Counted the same way as the database entries, so 1,2-헥산다이올 is one ingredient and splitting the Korean string at every comma returns 29 rather than 28. Set against the brand’s English list, both run to 28 entries, both open with aloe leaf water and close with potassium sorbate, and on both the four UV filters land at positions 5, 6, 8 and 9: link
