Check Promedial Cosmetic Batch Code

Its official lineup spans lotion, milk, cream, oil, mist, cleansing, masks, UV care, base makeup, body care and refills.

Promedial marks across sensitive-skin care and refills
Before you rely on the decoded date
- Check a bottle or mist can at the base and back label, a cream jar underneath, a tube at its sealed crimp, a mask on the sachet edge and a refill around the heat-sealed seams. Compare the primary package with its carton.
- Bottle and refill volumes differ, and labels may state cosmetic or quasi-drug status. Volume, SPF/PA, shade, legal sales name and the final a/b suffix are product information rather than the manufacturing mark.
Common lookup mistakes
- Photograph the Japanese 販売名 line with the short production mark so similar Moisture and White Moisture products are not mixed.
- Do not transfer a bottle's date to a refill pouch; each package should be read independently.
