Yes. A reputable medical spa or medical practice that performs injectable treatments should routinely document the lot number (and typically the expiration date) of every injectable product used in your treatment.
This is considered a best practice for patient safety because it allows the practice to:
- Trace exactly which product was used if there's ever a manufacturing issue or recall.
- Investigate unexpected reactions.
- Verify authenticity and inventory.
- Comply with manufacturer recommendations and professional standards.
For treatments such as:
- Botox
- Dysport
- Xeomin
- Jeuveau
- Hyaluronic acid fillers (such as products from the Juvéderm or Restylane lines)
the chart commonly includes:
- Product name
- Lot or batch number
- Expiration date
- Amount injected
- Injection sites
- Date of treatment
- Name of the treating clinician
Many offices use the peel-off barcode stickers that come on the manufacturer's packaging, placing one in the patient's chart and another in their inventory log.
If a practice doesn't record lot numbers, that isn't automatically proof of wrongdoing, but it would be below what many experienced aesthetic practices consider standard documentation. It also makes it much harder to identify affected patients if a product recall or safety concern arises.
If you're a patient, you can ask the office:
- "Can you tell me the lot number and expiration date of the product that was used during my treatment?"
- "Is that information documented in my medical record, and can I have a copy?"
Most well-run practices should be able to provide that information from your chart.
