Letybo: A Neurotoxin Option in Canada
Botulinum toxin type A is one of the most studied tools in aesthetic medicine. Letybo (letibotulinumtoxinA) is one of several formulations approved for use in Canada. This article explains what Letybo is, how this category of treatment works, what it is approved for, and the safety considerations involved—so you can have an informed conversation at your consultation.
What Letybo Is
Letybo is a botulinum toxin type A produced by Hugel, Inc., and available in Canada through Hugel Canada Inc. It was developed in South Korea, where it is widely used, and has an international track record across multiple markets. Health Canada approved Letybo on June 14, 2022, for the treatment of moderate to severe glabellar lines—the vertical frown lines between the eyebrows.
How It Works
Like all botulinum toxin type A products, Letybo works by temporarily reducing the release of acetylcholine at the neuromuscular junction. This relaxes the targeted muscle, which softens the dynamic wrinkles caused by repeated muscle movement. The effect is temporary and gradually wears off as normal muscle activity returns.
Botulinum toxin products differ in formulation and diffusion characteristics, which can influence how a clinician plans an injection. These are technical differences in how the products behave—not a measure of one being “better” than another. The appropriate choice depends on the individual, the treatment area, and clinical judgment.
What It Is Approved For
In Canada, Letybo is approved specifically for glabellar lines. As with other neuromodulators, clinicians may use botulinum toxin in other facial areas based on clinical judgment and the published literature; any such use is discussed with you in advance as part of informed consent.
Safety and What to Expect
As with any botulinum toxin treatment, the most common effects are temporary and localized—mild redness, swelling, or bruising at the injection sites, which typically resolve within a few days. Sessions are usually brief, and most people return to normal activities the same

As with any botulinum toxin treatment, the most common effects are temporary and localized—mild redness, swelling, or bruising at the injection sites, which typically resolve within a few days. Sessions are usually brief, and most people return to normal activities the same day. A medical assessment beforehand determines whether the treatment is appropriate for you and reviews your individual risks.
Where Letybo Fits
Several botulinum toxin type A products are approved in Canada, and they share the same basic mechanism. Choosing among them is a clinical decision made with you, based on your anatomy, your goals, the treatment area, and your previous experience with neuromodulators. There is no single product that is right for everyone—the choice is individualized.
