What to verify before booking

Ask for the exact product name, manufacturer, lot, total amount, injection sites and the name of the practitioner in writing. Products and injection protocols within the same broad category are not interchangeable.

These sources establish device or product identity and the scope of published research. They do not establish the Korean authorization scope of every model, an individual result, a fixed recovery time or superiority over another brand. The exact MFDS authorization document for each Rejuran product was not secured in this review.
