Korean beauty value: calculate your own cost per use
Compare current prices honestly, then estimate cost per use from your own consumption rather than a made-up dose.

Compare the current discovery shortlist
Choose a product role first. Prices below come from current public listings; they exclude delivery, duties and personal offers. This is a retailer selection, not a quality ranking.
| Brand & role | Exact product | Net size | Current price | Price per 10ml / 10g |
|---|---|---|---|---|
| SOOYA SEOUL · Body & hand lotion | Body & Hand Lotion - Lilac Veil | 400g | 28,800 KRW | 720 KRW / 10g |
| SOOYA SEOUL · Rinse-off wash | Body & Hand Wash - Lilac Veil | 400g | 26,100 KRW | 652.5 KRW / 10g |
| SOOYA SEOUL · Scent oil | Scent Oil - Lilac Veil | 50ml | 35,100 KRW | 7,020 KRW / 10ml |
Only compare unit prices for products with the same purpose and measurement unit. Grams and millilitres are not interchangeable; a tint, a gloss and a wash perform different jobs. Open the exact product to review its label, ingredients, directions and purchase options.
A Korean brand does not need the lowest sticker price to be useful, but value should be explainable. When comparing an Olive Young purchase with a discovery at THE CAST, begin with the same product category and the actual quantity in each offer. A body wash and a scent oil solve different problems, so a price-per-unit comparison across them is not a quality ranking.
What to compare before choosing
For two comparable products measured in grams, divide the current item price by the stated grams and multiply by 100 to compare price per 100 g. Keep shipping and any destination charges visible as a separate part of the basket total. Do not convert a 50 ml oil to grams or compare an offer containing multiple bottles with a single-bottle price without adjusting the quantity.
Make the discovery useful
Cost per use needs an observation you supply: how many uses you actually get from the product. Divide the amount you paid by that count after finishing it, or keep a clearly labeled estimate while using it. THE CAST does not assume everyone dispenses the same amount. A smaller first order can be the sensible value choice when you are uncertain about scent, shade or whether the format belongs in your routine.
