Refresh your expression with Letybo®, the next-generation wrinkle relaxer clinically proven to soften frown lines while preserving natural movement.
What Is Letybo®?
Letybo® (letibotulinumtoxinA-wlbg) is an FDA-approved neuromodulator designed to temporarily smooth moderate to severe glabellar lines—the vertical “11s” between the brows. Functionally comparable to BOTOX® Cosmetic, Letybo® works by inhibiting the release of acetylcholine at the neuromuscular junction, relaxing the corrugator and procerus muscles that cause frown lines.
What sets Letybo® apart is its international pedigree. It has been the leading neurotoxin in South Korea for the past nine years—a country recognized for its leadership in aesthetic innovation and advanced skincare science. Clinical studies have demonstrated a remarkably low rate of eyelid ptosis (0.5%), underscoring its proven safety and precision. The result: smooth, natural-looking rejuvenation that preserves your authentic expression.
