Letybo
Letybo® contains the active substance botulinum toxin type A. It works by blocking nerve impulses to the muscles in which it has been injected. It prevents muscles from contracting, leading to a temporary paralysis. Letybo® is used in adults less than 75 years of age to temporarily improve moderate to severe vertical lines between the eyebrows, when their presence has a significant psychological impact on them. Letybo® is a white lyophilized powder for solution for injection provided in a clear glass vial with a rubber stopper and aluminium tamper-proof seal.
