Letybo
INJECTABLES
Letybo is an FDA-approved botulinum toxin type A designed to temporarily improve the appearance of dynamic facial lines caused by repetitive muscle movement, such as frown lines, crow’s feet, and forehead wrinkles. Originally developed and widely used in South Korea, Letybo has earned recognition across Asia and Europe for its high purity, smooth diffusion, and natural-looking outcomes. Now available in the U.S., it represents a new generation of neuromodulators focused on precision, softness, and aesthetic balance.

Letybo, approved in the U.S. in 2023, has been widely used in Asia and Europe for years. It is known for its high purity and minimal accessory proteins, which may reduce the risk of resistance over time. Its smooth and even diffusion gives it a soft, natural finish, making it a great option for patients looking for a subtle, refreshed appearance.
One of the standout features of Letybo is its potentially faster onset. Many patients notice visible softening of lines within 2 to 3 days, slightly quicker than Botox, which typically begins to take effect around 3 to 5 days. Both products reach peak results around 7 to 14 days and typically last up to 3 to 4 months.

Letybo vs. Botox
Letybo and Botox are both FDA-approved botulinum toxin type A injectables designed to temporarily relax facial muscles and smooth dynamic wrinkles like frown lines, crow’s feet, and forehead lines. While they serve the same primary purpose, there are subtle differences that may make one a better fit depending on your goals.
