Check Infinity Cosmetic Batch Code
INFINITY is a KOSÉ beauty line launched for premium age-focused care and now spans cleansing, lotions, emulsions, creams, serums, masks, makeup, hair, body and sunscreen. Many items have refill or replacement versions, which must be matched to the formula container rather than the reusable shell.
Infinity FAQ
Which code should I use for an INFINITY refill?
Use the production mark on the sealed refill pouch, bottle or pan, not a molded code on the reusable outer case.
Is I, II or III the lot code?
No. Those labels can identify moisture or formula variants; the lot is a separate mark.
INFINITY KOSÉ lot marks by container and refill
Before you rely on the decoded date
- Inspect bottle and jar bases, tube crimps, pump collars and the lower or closing flaps of the individual carton. For a refill pouch, replacement bottle or compact pan, record the mark on the sealed refill and retain the reusable case only as supporting product identification.
- Series names such as Prestigious, product functions, I/II/III moisture levels, quasi-drug wording, shade and JAN barcode distinguish variants. They are not the lot and should not be substituted for a short printed or embossed production mark.
Common lookup mistakes
- Photograph the full Japanese name with the lot because INFINITY offers concentrated, intensive, limited-kit and refill products with related names.
- For sunscreen, eye care and active quasi-drug formulas, follow the printed instructions and treat seal, odor, color or texture changes as warnings independent of the estimate.
