Is 03 or 09 a Heavy Rotation batch code?
No. Those prominent two-digit numbers are shade identifiers used across the eyebrow range.
Check Heavy Rotation Cosmetic Batch Code
Heavy Rotation is Isehan's Japanese eye-makeup brand, best known for Coloring Eyebrow mascara and also sold as pencils, powders, liquid tints and lash mascara. Numbers such as 03 Ash Brown, 04 Natural Brown, 09 Natural Ash and 12 Grayish Beige identify shades, not production batches.
Heavy Rotation FAQ
Where should I look on Coloring Eyebrow?
Check the tube base and back printing, then the carton flaps if the box is available.
Can the eyebrow pencil and mascara use the same code location?
Not necessarily. Pencil marks are usually on the barrel or carton, while mascara marks are commonly on the tube or box.
Heavy Rotation codes on brow mascara, pencils and compacts
Before you rely on the decoded date
- On brow mascara and liquid products, inspect the tube base, neck and printed back label; keep the outer carton because its inkjet mark may be easier to read. For pencils, check the barrel near the cap and any carton flap; for powder compacts, inspect the underside label.
- Product words such as EX, Micro, Fake Liquid, Extra Volume and Extra Long distinguish formats. A short separate stamped or inkjet string is more likely to be the production mark than the large shade number beside the colour name.
Common lookup mistakes
- Photograph the Japanese and English product name together with the mark so Coloring Eyebrow is not confused with the lash mascara line.
- Compare tube and carton marks before entering a code; a barcode, shade number or cosmetic colour reference will not identify production timing.
