Letybo is Hugel's brand of botulinum toxin type A, the top-selling toxin in South Korea and recently FDA-approved in the US for frown lines. It works like other type A neuromodulators — softening dynamic wrinkles with results in about a week, lasting 3–4 months.
Letybo is Hugel's brand of botulinum toxin type A, the best-selling neuromodulator in South Korea and one of the newest entrants to the US market following FDA approval. It treats frown lines with the familiar onset and 3–4 month duration of other type A toxins, and arrives backed by extensive international use, giving practices a fresh, well-studied option to offer.
For a practice, Letybo is a competitive new toxin that can expand the menu and appeal to patients interested in the latest options — useful for differentiation and for negotiating supply. As with every neuromodulator, the path to 'yes' is reassurance: a simulated, natural result on the patient's own photo converts curiosity into a booked appointment.

Yes. Letybo received FDA approval for the treatment of glabellar (frown) lines and is now available in the US, after being the best-selling toxin in South Korea for years.
Both are botulinum toxin type A with comparable onset and 3–4 month duration. Letybo is newer to the US but extensively used internationally.
