Manufacture date and shelf life
Can I tell when my La Mer The Regenerating Serum was made from its batch code?
Yes, as an estimate. La Mer uses the Estée Lauder Companies format: for example, code A76 reads as July 2026. Results come from public reports, not from the brand.
How long does La Mer The Regenerating Serum last unopened?
La Mer does not publish an unopened shelf life we could verify (checked October 2026). Go by the date printed on the pack; Korean imports always carry one on the Korean label.
How long can I use it after opening?
Look for the open-jar symbol on the pack (for example 12M = 12 months after opening). Our period-after-opening calculator gives the exact date.

- Contains fragrance or essential oils (Fragrance). Skip it if fragrance irritates your skin.
- Fragrance allergens listed: Eucalyptus Globulus Leaf Oil, Limonene, Linalool, Hydroxycitronellal, Citronellol, Geraniol. In the EU these must be named when above 0.001% in leave-on or 0.01% in rinse-off products.
- Alcohol Denat. appears at #93, lower down the list, so the amount is likely small.
What most of it is made of
- WaterBase
- Algae ExtractPlant extract
- DimethiconeSilicone
- Hdi/Trimethylol Hexyllactone CrosspolymerThickener / texture
- Hydrogenated PolyisobuteneEmollient
1% line: from Phenoxyethanol (#102) onward, ingredients are probably at 1% or less. Phenoxyethanol is limited to 1% in the EU, and ingredients at 1% or less may be listed in any order. Products made only for other markets can use more.
