Seoul Skin Notes

Korea's Consumer Agency sent ten foam cleansers sold in Korea to a lab and printed the measured pH of every one. Round Lab's 1025 Dokdo Cleanser came back at 5.7. Dr.G's Green Deep Pore Clear Foam came back at 6.0. The remaining eight ran from 7.2 up to 10.0. If you're somewhere between 25 and 40 with combination or oily-but-dehydrated skin in a humid city, and you switched to Korean cleansers partly because a forum thread told you they run gentler and lower pH than Western foaming washes, those are the numbers worth sitting with for a minute. Eight of the ten products in the panel are Korean brands. Six of those eight measured between 9.4 and 10.0. What the agency put in the lab The report is 비교공감 제2024-20호, published 19 November 2024 by the Korea Consumer Agency, on the government's Consumer24 portal. It covers cleansing power against two soils (cleansing oil and sunscreen), a user panel for feel and rinse-off, pH, safety testing for preservatives and heavy m...

From October 18, 2026, a cosmetic sold in Indonesia has to carry either a halal certificate or a non-halal marking, and that includes the Korean serum in your Shopee cart. Korea's Ministry of Food and Drug Safety (식약처) gave that date in an August 3 announcement about a delegation it had sent to Jakarta, and the Indonesian side has spent the summer publishing the fine print. If you are in your twenties in Jakarta or Surabaya, oily skin in year-round humidity, and you buy Korean skincare through Shopee or a local distributor, this is what changes on the shelf next month. Readers in Malaysia and Singapore, your national rules are different, though the ingredient part below applies to you too. Two dates, one deadline Korean coverage says October 18. English-language compliance guides say October 17. The Halal Foundation's news page opens with "Starting October 17, 2026, Indonesia will enforce mandatory halal certification for a wide array of products, including food and ...

Where to buy Korean skincare in the UK got a new answer this morning (14 September, KST). Hanjin (한진), the Korean logistics group, said it is scaling up a fulfilment centre it built in Southampton in April, because Korean beauty brands started moving their Black Friday and Boxing Day stock into Britain this month. On its face that is a supply-chain press release. Read the Korean version and it is the most useful thing I've read on the question this year: increasingly, the answer is a warehouse in Hampshire. This one's for UK buyers, 25 to 45, who already have a Beauty of Joseon sunscreen on the go and are deciding whether to wait for the November sales or order from Seoul now. Damp, centrally heated, indoor-winter skin. What Hanjin said, in Korean The English write-up in Seoul Economic Daily includes the location and the square metres. The Korean originals in Money Today (머니투데이) and Herald Economy (헤럴드경제) carry the timing, the detail that matters most here. Hanjin says ...

For "Korean skincare vs CeraVe," the usual answer, Illiyoon's Ceramide Ato Concentrate Cream, isn't the three-ceramide match people assume it is, and this week it isn't the cheaper jar either. This is written for dry, barrier-stressed skin trying to choose between the jar you already trust and the Korean one your feed keeps pushing at you, through city-dry winters, hot showers, and retinol nights. CeraVe's tub is the default recommendation on pretty much every US dermatology thread. Ask the same question on a Korean skincare forum and Illiyoon's Ceramide Ato Concentrate Cream comes up almost every time, usually framed as the gentler, cheaper version of the same idea. Nobody in either thread tends to open the actual ingredient panel before saying so. What's Actually in Each Jar CeraVe's full INCI list names three ceramides (Ceramide NP, Ceramide AP, and Ceramide EOP, what CeraVe's own site calls "ceramides 1, 3, and 6-II") in a ...

Toner, essence, serum, ampoule. Go to COSRX's own website and look for the second item on that list. There isn't one. The category is called "Serums & Essences," one collection, no dividing line. Search SKIN1004's site the same way and the navigation runs "Toner & Mist" straight into "Ampoule & Serum," skipping essence entirely. Do the brands themselves even agree on where essence starts, or whether it's a category at all? This one's for anyone standing in front of an Olive Young shelf or four open tabs, trying to work out whether the $22 "essence" and the $34 "serum" next to it are genuinely different things, or just different labels on similar bottles. Essence Was Invented as a Marketing Category, Not a Formula Essence didn't emerge from a chemistry difference the way, say, an ampoule's higher active load did. It emerged because Korean brands wanted a hydration-and-absorption step between ...

Pull up the ingredient list for Beauty of Joseon's Relief Sun: Rice + Probiotics next to Round Lab's Birch Juice Moisturizing Sun Cream and twelve of the first thirteen ingredients run in the same order; Round Lab just lists Tinosorb M one slot earlier, ahead of niacinamide instead of after it. Same four UV filters, same base, same SPF50+ PA++++ on the label. Beauty of Joseon vs Round Lab sunscreen comparisons keep landing in the same two-way tie on forums for exactly that reason: the bottles look like they should perform identically, and mostly they don't. Dry-to-normal skin in a dry climate chasing a dewy finish, and oily or acne-prone skin in a humid one that wants sunscreen to disappear: that's the split this comparison is written for, the kind of reader standing in front of two nearly identical white bottles on an Olive Young shelf, or with both tabs open on Target.com, trying to work out whether the price gap buys anything real. The Filters Are Nearly a Carbon...

Anua's PDRN serum and COSRX's snail mucin essence have both spent this September sitting near the top of Olive Young Global's bestseller list, and they're marketed almost identically: plump, glowy, "glass skin" hydration in a dropper bottle. The ingredients behind them don't do the same job at all. Does the marketing on the bottle reflect that gap? This one's for normal-to-dry skin chasing plumpness and glow. Acne-prone skin hunting something to fight breakouts should look elsewhere. Neither ingredient does that. What PDRN Is, and Why It Started as an Injection PDRN stands for polydeoxyribonucleotide, purified from salmon or trout sperm DNA. It's not a K-beauty invention. It's been used in wound-healing medicine across Europe and Asia for over two decades before Korean clinics started injecting it as a skin "booster" under the brand name Rejuran , sometimes nicknamed the salmon injection. The mechanism described here is real biol...

You dig a foil sheet mask packet out of a drawer, leftover from an Olive Young sale you don't fully remember, and flip it over looking for a date, but none of it looks like anything printed on a Sephora shelf. Two lines of small print sit next to a tiny icon of an open jar, with a number beside it. This one's for anyone with a backlog of half-forgotten sheet masks and serums from two sales ago. What do the numbers on the back actually mean? The Three Numbers Korean Packaging Prints Korean cosmetics labels run on a different system than most Western drugstore shelves, and it's not one number. It's up to three, and they don't mean the same thing. 사용기한 , or a date followed by 까지 ("until"), is the use-by date, a hard stop, printed as YYYY.MM.DD. "2028.06.09까지" means stop using it after June 9, 2028. 제조일자 (or just 제조) is the manufacturing date, not an expiry. When a brand prints only this, ShopAtKorea explains , you're expected to add a st...

A cosmetic chemist recently had to go on the record, in Essence, explaining that Korean skincare doesn't bleach anyone's skin. Enough people were asking that someone had to answer it plainly. This is for anyone with Black or deep-brown skin circling the K-beauty aisle but stuck on two things — sunscreen reviews that never say how a formula performs on melanin-rich skin, and "brightening" language that sounds like it might mean something you don't want. Checked September 11, 2026. Does "Brightening" Mean Lightening? No. Not on its own. Mibaek (미백), the Korean word cosmetics use, translates loosely to "whitening," and English marketing copy softens that to "brightening" without explaining the gap. Under Korea's own cosmetic rules the term is narrower than either translation suggests: pulling melanin in an existing dark spot back down to your own baseline, not lightening skin that was never dark to begin with. The ingredient actu...

Olive Young's first US store opened in Pasadena on May 29, 2026, the same week the company cut off the global website millions of shoppers outside Korea had been ordering from for years. This piece is for anyone who used global.oliveyoung.com to order from outside Korea and just got bounced to something new, or anyone near a Westfield mall wondering if a physical store actually changes the math. Checked September 10, 2026. What's Inside the Pasadena Flagship The flagship sits at 58 W Colorado Blvd, 8,647 square feet, and carries roughly 400 brands and 5,000 SKUs across skincare, makeup, hair, and wellness, per Olive Young's own press release . There's a skin scan station and a scalp analysis service, the kind of in-store extras a website can't replicate. Gaeun Kwon, CEO of Olive Young USA, said: "At OLIVE YOUNG, we aim to create a space where customers can discover what works best for them — both in-store and online." A second location at Westfield C...

"How to use Korean toner pads" gets typed into search bars constantly, and the honest answer changes depending on which pad is in your hand. Some have a raised side and a smooth side. One popular bestseller doesn't have a textured side at all. A few are quietly delivering a real acid while they're at it. Written for: anyone who just added a two-sided cotton pad to their routine and isn't sure which side goes where, or whether "safe for daily use" on the label applies to every pad in this category. Checked September 10, 2026. The Embossed Side Buffs, the Smooth Side Finishes Anua's Heartleaf 77 Toner Pad and Round Lab's Birch Juice Cleansing Pad both use the same two-sided disc, and both brands give near-identical directions for it. Anua's own product page says to "swipe embossed side across face avoiding eyes and lips," then "flip to smooth side and press onto skin as a hydrating mini face mask." Round Lab's listi...
