## Buyer Question
Which serum theme or ingredient angle is worth testing in the target market?

## Commercial Path
Signal Sprint: $500 USD
Send buyer brief + sample CSV + seller signal pack, then route serious buyers to the deal desk and operator-approved invoice path.
Growth Feed at $1,500/month after one category proves useful.

## Market Entry
Seller angle: Ingredient-led sellers need product candidates, Korean naming, and trend timing in one feed.
First test: Group product candidates by ingredient angle, price band, and trend signal before supplier outreach.
Compliance prompt: Treat ingredient and claim checks as source mapping only; do not present this as cosmetic compliance clearance.
This is source mapping and sourcing prioritization, not legal, tax, customs, medical, or investment advice.
