Where is the Yuzuyu batch code?
Check the container base, lower rear label, refill-pouch seam, crimp and carton for a separate short mark.
Check Yuzuyu Cosmetic Batch Code
Utena's Yuzuyu range uses Japanese yuzu in hair oil, oil mist, refill packs and hair milk for different causes of frizz and spread. Hair Oil, Oil Mist and Hair Milk identify the formula and application, not the production lot.
Yuzuyu FAQ
Is Hair Oil or Oil Mist the batch?
No. Those names distinguish Yuzuyu product formats.
Does the yuzu ingredient wording reveal the date?
No. It describes the range and ingredients, not manufacturing timing.
Reading Utena Yuzuyu hair-care markings
Before you rely on the decoded date
- Inspect bottle and pump bases, the lower rear label, refill-pouch seams, tube crimps and carton flaps. A moulded number on a cap or pump component is packaging information rather than necessarily the filled-product lot.
- Separate the product name, refill wording, volume, barcode and Utena item reference from a short inked, stamped or embossed traceability mark.
Common lookup mistakes
- Keep oils and milk tightly closed and avoid heat and sunlight; use clean hands and do not let the applicator contact wet or dirty surfaces.
- Follow printed expiry or PAO first. Stop use if the seal is damaged or the scent, colour, separation or consistency changes unexpectedly.
