Azzalure and Alluzience are botulinum toxin type A prescription-only medicines associated with Galderma, but they are not interchangeable products. For UK aesthetic practitioners, one of the most obvious practical distinctions is presentation: Azzalure is supplied as a powder requiring reconstitution in accordance with its product information, whereas Alluzience is a ready-to-use liquid formulation.
Relfydess adds a third Galderma toxin presentation to the comparison. It is also supplied as a ready-to-use solution for injection, but it remains a distinct medicine with its own potency units, authorised product information, storage requirements and prescribing considerations.
