Package-mark guidance for Prequel
Before you rely on the decoded date

- The final decision should reflect large pumps and sensitive-skin actives, seal condition, and any explicit package directions.
Common lookup mistakes
- Find the lot around pump bases, tube crimps, jar labels, and cartons, and exclude any UPC, SKU, item number, or fixed artwork reference nearby.
- Preserve the package directions and stop using the item if large pumps and sensitive-skin actives indicate deterioration or contamination.
