Check Fasio Cosmetic Batch Code

Products sold under FASIO span mascara, eyeliner, eyebrow product, base makeup, lip color, and setting product. That variety matters because the useful lot can move between a base, seam, label, crimp, or outer package.

Fasio FAQ

Which FASIO number is the manufacturing lot?

Start with tube and pencil bases, compact backs, bottle bottoms, and Japanese cartons and keep the compact manufacturing string. Leave out shade numbers and waterproof claims, even when those numbers are more prominent.

Where should I look when a FASIO lot is not obvious?

No. mascara, eyeliner, eyebrow product, base makeup, lip color, and setting product use different containers, so inspect the immediate package and retain any outer carton until the check is complete.

Is a recent FASIO date enough to judge mascara, eyeliner, lip color, or base makeup?

For the product in hand, no. Use it with printed expiry or PAO, packaging integrity, purchase source, storage history, and the formula's current condition.

FASIO makeup batch code and opening-date check

Before you rely on the decoded date

  • The most useful search areas are tube and pencil bases, compact backs, bottle bottoms, and Japanese cartons. Photograph any compact lot there, but exclude shade numbers and waterproof claims before entering it.
  • Powder, liquid complexion products, eye makeup, and lip color age differently after opening. Use the printed PAO and applicator hygiene alongside the production estimate.

Common lookup mistakes

  • With FASIO, preserve the Japanese mascara, eyeliner, brow, base, lip, or setting-product label around the code. Slim makeup cartons are easier to identify before they are flattened.
  • A plausible date does not override odor change, oil separation, hardening, drying, applicator contamination, or eye irritation; those signs call for a conservative product decision.

What to check next for Fasio
