THE CAST shares an ampoule set comparison guide
A first-party update about comparing K-beauty ampoule set contents online.
Published
9 November 2026 — THE CAST published an English guide to comparing K-beauty ampoule sets before ordering online. This first-party update is from THE CAST, an online K-beauty seller.
Check the individual bottles
The guide suggests recording the number of bottles and the stated size of each. Sets with the same total volume may have different packaging and contents. Bottle count alone does not determine the number of applications.
Compare matching products
For a meaningful unit-price comparison, shoppers can compare the same product and formula in the same units. The guide recommends checking that the written contents match the option selected in the cart.
Review current labels and order terms
Shoppers can read each item's ingredient list, directions and warnings, request a readable label if needed, and confirm availability, delivery eligibility, total charges and return terms. This update does not promise availability, delivery or individual results.
