Me comparing one blue serum bottle across five US websites like I’m doing a PhD in hyaluronic acid. 🔬💙
Quick answer: On 6 October 2026, the single 50ml bottle was $21.17 on Stylevana US and $24 at Torriden US. The number that matters: $30.99, Torriden US’s $24 plus its published $6.99 shipping, before tax. That’s the bar any other single-bottle offer has to beat. Want two bottles? Olive Young US’s $26.99 duo is the one to check first.
I checked 5 US-facing shops’ product pages and shipping policies on 6 October 2026. No test order, no fake receipts, just the math.

Torriden is all about hydration, and Huh Yunjin’s Vogue Beauty Secrets episode is a whole hydration mood. Watch while I do sums:
Single 50ml bottle: who’s listing what
Same bottle, same size, five very different vibes.
| Shop (50ml single) | Listed price, 6 Oct 2026 | What matters |
|---|---|---|
| Stylevana US | $21.17 | Showed “In Stock, usually shipped within 24 hours.” US shipping not verified. |
| Torriden US | $24.00 | Published continental-US shipping: $6.99 below its free-shipping threshold. |
| Soko Glam | $24.00 | Showed “Sold out” when checked. |
| YesStyle | Not confirmed | Showed a destination-unavailable message in my session. |
| Amazon | Check live | Confirm size, seller and one-time vs subscription. |
The shipping math: Stylevana has a $9.82 allowance
This is the part sticker-price lists skip.
Torriden US’s shipping policy lists $6.99 standard delivery to the continental US. So one bottle is $24 + $6.99 = $30.99 before tax. Stylevana’s $21.17 leaves $9.82 for shipping and other non-tax charges before it stops being cheaper. I didn’t verify Stylevana’s US shipping, so treat this as a decision rule, not a verdict.
| Stylevana shipping + other non-tax charges | Stylevana pre-tax total | Against the $30.99 benchmark |
|---|---|---|
| $5.00 — illustrative | $26.17 | $4.82 lower |
| $9.82 — break-even | $30.99 | Equal before sales tax |
| $12.00 — illustrative | $33.17 | $2.18 higher |

Two bottles? The duo changes everything
Plot twist: the cheap-looking Olive Young price was a duo.
| Two-bottle offer | Listed subtotal | Catch |
|---|---|---|
| Olive Young US: 50ml × 2 | $26.99 (~$13.50 a bottle) | Under its advertised $35 free-shipping line; my address shipping not verified. |
| Torriden US: Duo Set | $44.00 | $50.99 with its published $6.99 shipping, before tax. |
For two bottles you’ll actually use, Olive Young US is worth checking first. For one bottle, don’t buy a duo just because the unit price looks cute.
