Most counterfeits waste your money. A counterfeit car seat gambles with the one passenger who cannot choose, in the one crash nobody schedules. Fake and non compliant child seats have been found on marketplace and discount channels repeatedly, dressed in the colours and logos of brands parents trust, built without the testing, materials, or energy management that make the real thing boring in a collision.
This is not a category for bargain instincts. It is a category for provenance, and the checks below are the ones safety organisations and manufacturers themselves publish, in plain form.
A genuine water filter for a stated standard can be found in the certifier's own listing, under the exact model number, naming the standard it was tested to. Counterfeits copy the box art and the certification logos while appearing in no listing at all. Checking the model in the certifier's database takes two minutes and settles what packaging never can.
No single check authenticates a skincare product. Batch and lot codes in the brand's real format and placement, crisp printing, a properly constructed seal, and texture and scent matching a known genuine reference form a combined picture. Two or more mismatches across independent checks is where suspicion becomes a reportable case.
Brands print batch codes in consistent formats at consistent locations: crimped into a tube seam, etched on a jar base, printed under a label edge. A code in the wrong format, wrong place, or printed in a font the brand does not use is strong evidence because counterfeiters copy the visible design and routinely fumble the coding system they cannot see operating across the range. Photograph codes on both the suspect and a genuine reference side by side; the comparison is the evidence, not either photo alone.
Do not overclaim what a code lookup proves. Public code checkers estimate production dates from formats and databases of varying quality. A plausible date is consistent with genuine stock and with a copied code; an impossible date or a format that never existed is the informative result. Treat lookup tools as one signal in the stack.
In hand, weight and finish separate many fakes: thinner plastic, seams that catch a fingernail, lids that seat unevenly, labels applied a degree off true, text with the soft focus of a photograph of printing rather than printing itself. Spelling errors still occur but are the least reliable tell now; better counterfeits proofread. The reliable tells are manufacturing tolerances, because the fake is made in a different factory with different tooling, and tooling differences cannot be edited like text.
Seals deserve their own look. A genuine induction seal removes cleanly in one piece with printed text intact. Foil that shreds, adhesive residue patterns that differ from the genuine article, or a seal missing under a cap that should have one are findings worth photographing before the product is used, because use destroys exactly this evidence.
Texture, colour, and scent drift versus a genuine reference are real signals and also the point where caution takes over. Counterfeit skincare is not merely ineffective; uncontrolled manufacturing means contamination and undeclared ingredients are live possibilities, and skin is a poor laboratory. A suspect product that also smells off, separates, or irritates should be treated as a safety report, not a bargain to finish.
Report with the full evidence set: listing, codes, packaging comparisons, purchase records. Marketplaces and brand protection teams act on documented cases, and skincare counterfeits sit high in their priority order precisely because of the safety exposure. Your report protects the next buyer more than it refunds you, though documented cases usually achieve both.

No. Codes can be copied from genuine products. A code in the brand's correct format and placement is one supporting signal; an impossible format is strong negative evidence. Authentication rests on several independent checks agreeing.
Side by side comparison with a product bought from an authorised retailer: codes, print sharpness, seal, weight, texture. Differences that repeat across those independent features are far more telling than any single flaw.
It can be. Unregulated manufacturing risks contamination, wrong concentrations, and undeclared ingredients. Suspect products that irritate or smell wrong should be stopped and reported rather than used up.
To the marketplace with the listing and evidence, and to the brand's protection channel with the same file. Keep the product and packaging until both respond; the physical item is often requested as part of the case.
