Is Stem Science a separate company from Episteme?
No. It is a product series within Episteme, a Rohto Pharmaceutical skincare brand.
Check Stem Science Cosmetic Batch Code
Stem Science is an advanced skincare series within Rohto Pharmaceutical’s Episteme brand, not a generic label for every product that mentions stem-cell research. The range spans cleansing cream, face wash, lotion, emulsion, lift and eye creams, oil and concentrated serums, CC products, and a separately regulated beauty drink.
Stem Science FAQ
Can the Stem Science drink use the skincare batch result?
No. The drink is an ingestible product and should be judged by its explicitly printed food date and storage directions.
Do Stem Science lotion and cream share one batch?
Not necessarily. They are separate formulas filled in independent production runs, even when sold as one routine.
Check an Episteme Stem Science batch code
Before you rely on the decoded date
- Inspect bottle and jar bases, tube crimps, pump labels, refill seals, and carton flaps for a compact printed or embossed lot. “Stem Science,” RX, CC, product size, JAN barcode, and a skincare step identify the formula or retail item rather than its manufacturing run.
- Topical cosmetics, face powder, sunscreen-style CC products, and ingestible beauty drinks are different product classes. Do not apply a cosmetic batch interpretation to a drink, or use one routine item’s mark to date the rest of a set.
Common lookup mistakes
- Record Episteme, the complete Stem Science product name, refill or full-size status, and both container and carton marks before discarding any packaging.
- Keep pumps, jars, and eye-product applicators clean and closed; for the drink, follow the printed food date and storage instructions instead of a cosmetic estimate.
