Where is a Sesderma batch code?
Check container bases, dropper collars, tube crimps, ampoule trays and carton flaps for a LOT string near any printed expiry.
Check a Sesderma skincare batch mark
Spanish dermocosmetic brand Sesderma groups products into Azelac, Azelac RU, C-VIT, Acglicolic, Retises, Sensyses and other collections. Ingredient percentages, acid names, liposomal or Nanotech wording, SPF, ampoule counts and face-care claims identify formula and use; they are not manufacturing codes.
Sesderma FAQ
Is Azelac RU or C-VIT the lot code?
No. These are Sesderma collection names that identify the formula family.
What if Sesderma prints an expiry date?
Use the explicit printed expiry and keep it separate from the lot; do not replace it with an estimated date.
Separate collection, active strength and lot information
Before you rely on the decoded date
- Inspect the bottle, jar or ampoule carton base, dropper collar, tube crimp, ampoule tray and outer-carton flap. Spanish and multilingual packs may place an explicit CAD/EXP date beside a separate LOT string; use the printed date when present.
- Record the full collection and format. Azelac gel, cream, lotion and mask differ, while Acglicolic serum, nourishing cream and ampoules carry different acid strengths and directions.
Common lookup mistakes
- Do not enter 8%, 15%, C-VIT, RU, SPF or the ampoule count as the lot code.
- Follow acid, retinoid and sunscreen directions on the label; active-care tolerance and an explicit expiry take priority over a cosmetic date estimate.
