What 2026 activity shows
Lookup attempts span established global names, regional labels, fragrance houses, pharmacy skincare, and newer direct-to-consumer brands. Isolated attempts are not presented as trends.
The strongest signal is aggregate brand-level interest. It helps identify where package-location guidance, expiry context, and product-category advice deserve deeper coverage. It does not expose or reverse-engineer any batch-code format.
How old are the products people check?
Across all brands, the typical product checked on Lot Date from Jun 12, 2026 to Oct 10, 2026 was dated to about 25 months before it was checked. The middle half of checks fell between 12 and 43 months, and about 35% were dated more than three years before the check.
The table covers the brands that currently have a Lot Date check guide, listed alphabetically. Differences between brands partly reflect how precisely each brand’s codes can be dated, so it is not a ranking of how old each brand’s stock is.
| Brand | Typical estimated age when checked | Middle half of checks | Dated more than three years earlier |
|---|---|---|---|
| Amouage | 23 months | 13–43 months | 35% |
| Aveeno | 21 months | 9–50 months | 35% |
| CeraVe | 17 months | 8–35 months | 25% |
| Chanel | 21 months | 10–40 months | 30% |
| Christian Dior | 27 months | 13–49 months | 35% |
| Giorgio Armani | 24 months | 14–41 months | 30% |
| Jean Paul Gaultier | 18 months | 10–32 months | 20% |
| L'Oréal | 16 months | 7–38 months | 25% |
| Maison Francis Kurkdjian | 20 months | 9–38 months | 30% |
| Parfums de Marly | 16 months | 10–32 months | 20% |
| The Ordinary | 17 months | 10–31 months | 20% |
| Tom Ford | 31 months | 14–55 months | 45% |
| Versace | 13 months | 8–20 months | 15% |
| Yves Saint Laurent | 22 months | 12–38 months | 25% |
These are estimates from successful Lot Date readings on the website and apps with at least month-level precision, so unlike the activity sections they only include checks that produced a production date. Repeat checks of the same code by the same visitor count once, and no visitor counts more than 20 times per brand. Product barcodes entered by mistake, readings dated after the check and readings that would make a product more than 15 years old are left out. Ages are rounded to whole months and shares to the nearest 5%. They describe the products people chose to check, not shelf stock or sales.
Activity tiers
The report uses broad qualitative tiers so readers can compare recurring patterns without exposing site traffic or individual brand totals.
| Tier | How to read it | Brands |
|---|---|---|
| High activity | Brands appearing most consistently across the reporting period | 124 |
| Frequent activity | Brands with recurring aggregate lookup interest | 334 |
| Established activity | Brands with enough grouped activity to describe a broad pattern | 198 |
How the year-to-date view is compiled
The report uses anonymous web lookup attempts from January 1, 2026 through Oct 10, 2026. Brand names are normalized before aggregation, incomplete calendar days are excluded, and only broad country patterns supported by sufficient grouped activity are included.
Submitted batch codes, IP addresses, client identifiers, individual timestamps, exact totals, publication cutoffs, and decoding rules are not included in the report. The same aggregation method is applied to every brand and region.
The patterns describe lookup interest across the reporting period. They do not show whether a lookup produced a result and do not imply a recall, product defect, counterfeit issue, or change in manufacturing rules.
The production-age section is the exception: it uses successful website and app readings from Jun 12, 2026, as explained in that section.
