FDA-approved neurotoxin for frown lines and dynamic wrinkles — natural, confident results with no downtime.
Letybo (botulinum toxin type A) is an FDA-approved injectable neuromodulator used to temporarily smooth moderate to severe glabellar lines — the vertical frown lines that form between the eyebrows from years of squinting and concentrating.
Developed in South Korea and used internationally for over a decade, Letybo received U.S. FDA approval in 2023 following Phase III clinical trials that demonstrated safety and efficacy on par with Botox. It works by inhibiting acetylcholine release at the neuromuscular junction, causing temporary, targeted muscle relaxation.
At Naya Wellness in Chatsworth, our board-certified providers use Letybo as part of a personalized aesthetic treatment plan — one that respects your natural expressions while smoothing visible signs of aging.
Letybo’s high-purity formulation offers consistent, predictable results — especially for patients new to neuromodulators or looking for an alternative to Botox and Dysport.
Approved for glabellar lines in adults following rigorous U.S. clinical trials in 2023.
Smooths lines without a frozen appearance — preserving authentic facial expression.
Visible improvement within 3–5 days, with full results at 10–14 days post-treatment.
Long-lasting results with regular maintenance appointments every 3–4 months.
Return to work and normal activities immediately after your 10–20 minute treatment.
High-purity formulation well-tolerated in clinical trials, including for patients with Botox sensitivity.
The entire process is quick and comfortable. Most patients describe the injections as a mild pinch. A topical numbing agent is available for added comfort.
