THE CAST publishes a 50 ml Korean serum and essence shopping comparison
The new guide compares stated sizes, observed prices and order checks for two Korean skincare listings.
Published
THE CAST has published a first-party comparison of smoothus Hydro Barrier Balancing Serum and LUMIPURA Hyal Shot Ampoule Essence. Both product names state a 50 ml size, allowing a straightforward price-per-volume illustration while keeping the products’ different formulas separate.
What was compared
The guide links the two product pages and records the prices shown on 10 November 2026: KRW 26,600 for smoothus and KRW 40,000 for LUMIPURA. Its per-10 ml figures are arithmetic examples before shipping and offers, not a promise of current prices.
What to check before ordering
Readers are directed to check each current listing, ingredients, directions and selected option. The final cost depends on the delivery destination and checkout; international taxes or clearance fees may be separate.
Source and independence
This is an update by THE CAST about its own shopping guide. It is not an independent performance test and does not claim the two formulas or their effects are equivalent.
