Tell me you buy K-beauty online without telling me: you have the same serum in four carts and you’re emotionally attached to all of them. 🛒🛒🛒🛒
Quick answer: Stylevana usually wins for 3 to 4 single bottles with my code SV15SEOULBD. YesStyle wins for mixed Korean + Japanese hauls. Olive Young wins for promo sets and 1+1 refills. For just 1 or 2 bottles fast, iHerb (code PNF305) or Amazon from US warehouses often beats paying international shipping.
I live in Seoul, shop Olive Young in person, and I keep comparing these five shops on this blog. Here’s the short version, minus the 4,000 words of spreadsheet trauma.

The 5 shops at a glance
Same products, very different boxes.
| Shop | Ships from | Wins when | Watch out for |
|---|---|---|---|
| Stylevana | Hong Kong | 3 to 4 single bottles, Korean sunscreen formulas, code SV15SEOULBD | One slow-stock item can hold the whole box |
| YesStyle | Hong Kong | Mixing Korean and Japanese brands in one order | Compare the same size, prices move |
| Olive Young | Korea (Global) or the US store | Promo sets and 1+1 refill bundles | US addresses need Olive Young US |
| iHerb / Amazon | US warehouses | 1 or 2 bottles you want fast | On Amazon, check “Sold by” and “Ships from” |
When Stylevana wins (and the stock rule)
Stylevana is my go-to for 3 to 4 single bottles. My code SV15SEOULBD gives 10% off any order, or 15% off $59+ when you’re logged in. Before checkout, read the stock line under every item: “ships within 24 hours” is what you want. One slow item can hold your whole parcel, and nobody has time for that. 🙃 More in my Stylevana code guide.
When YesStyle wins
If you’re mixing Korean staples with Japanese sunscreens, YesStyle has the biggest combined catalog in one box. UK, EU and Canada shoppers: check whether tax is collected at checkout before you pay.
When Olive Young wins
Promo sets. That’s the whole tweet.
Olive Young bundles things like a 50ml serum plus a refill, or a pad box plus a refill pouch. Per ml, that’s hard to beat. On a single bottle, though, it often looks pricier. US shoppers: the Global store no longer ships to you, so use Olive Young US.
When iHerb or Amazon wins
Small cart? Overseas stores punish small carts with shipping fees. For one serum and one toner, US warehouses usually win. Breakdown: K-beauty free shipping math.
