Where to buy Korean serum online: comparing two 50 ml listings
A first-party comparison of smoothus serum and LUMIPURA ampoule essence listings.
THE CAST is a Korea-based online store where shoppers can browse Korean skincare. This retailer-authored guide compares the published listings for smoothus Hydro Barrier Balancing Serum and LUMIPURA Hyal Shot Ampoule Essence, two different products whose names each state a 50 ml size.
Compare the same stated volume
The smoothus listing identifies a 50 ml serum; the LUMIPURA listing identifies a 50 ml ampoule essence. The same stated volume makes a price-per-volume calculation possible, but it does not make the formulas, directions or individual results equivalent. Read the full product information on both pages.
Prices at the time checked
On 10 November 2026 the displayed THE CAST prices were KRW 26,600 for smoothus and KRW 40,000 for LUMIPURA. Dividing each by five gives KRW 5,320 and KRW 8,000 per 10 ml, respectively, before delivery or any personal offer. These are snapshots, not promised current prices; check each listing again before ordering.
Compare the final order
Shipping depends on the chosen products and destination, and international eligibility can differ by item. Compare the checkout total for the same destination and review possible import taxes or clearance charges separately. The store’s EMS table is a reference, not the final order quote.
Ingredients, directions and support
Product names and unit prices cannot establish whether either formula is appropriate for an individual. Review the available ingredient and direction information, select the exact option, and ask the seller when essential details are unclear. Check current return and exchange conditions before payment.
