If you’ve been keeping up with the neuromodulator options at Simply Radiant, you already know the lineup includes Botox, Dysport, Xeomin, Jeuveau, and Daxxify. Letybo is the newest addition to that world, and it’s worth understanding what it actually is before deciding whether it fits your treatment plan.

What Letybo Is
Letybo (letibotulinumtoxinA-wlbg) is a botulinum toxin type A injectable, manufactured by Hugel, a South Korean biopharmaceutical company. It received FDA approval in 2024 for the temporary improvement of moderate-to-severe glabellar lines, the vertical “11” lines that form between the eyebrows from frowning and squinting. Before its U.S. approval, Letybo had already built a substantial track record internationally, including a leading position in South Korea’s neurotoxin market and use across dozens of countries.
How It Works
Like every neuromodulator on the market, Letybo works by blocking the release of acetylcholine, the neurotransmitter responsible for triggering muscle contraction. When that signal is interrupted at the injection site, the targeted muscle temporarily relaxes, which softens the wrinkles caused by repeated movement in that area. This is the same underlying mechanism as Botox, Dysport, Xeomin, Jeuveau, and Daxxify; the products differ in their specific formulation and manufacturing process, not in the basic science behind how they work.
What Makes Letybo Different
Letybo is manufactured using a multi-step purification process to ensure consistent potency and structural stability. While it is a standard 900 kDa complexed toxin (retaining accessory proteins similar to Botox and Jeuveau), its controlled manufacturing standard gives it a predictable clinical profile. Clinically, Letybo’s onset and duration line up closely with other established neuromodulators, with visible results typically appearing within two to three days and lasting approximately three to four months.

What Letybo Is FDA-Approved to Treat
Currently, Letybo’s FDA approval covers glabellar lines specifically. Areas like the forehead, crow’s feet, and other commonly treated zones fall outside that approved indication for now, similar to how many neuromodulators start with a narrower approval before expanding to additional areas over time. If your goals include treatment areas beyond glabellar lines, your provider can walk you through which product, Letybo or another established neuromodulator, is the appropriate choice for that specific area.
What to Expect During and After Treatment
The treatment process for Letybo is fast and straightforward, typically taking only 10 to 15 minutes. Your provider uses a tiny needle to inject small amounts into targeted muscle points with minimal discomfort. There is virtually no downtime, so you can return to your normal routine immediately after leaving the clinic. Standard post-care recommendations include avoiding strenuous exercise, lying flat, or rubbing the treated area for at least four hours after your appointment to ensure optimal placement. Temporary side effects are typically mild and localized, such as slight redness, minor swelling, or light bruising at the injection site.
How Letybo Compares to Botox
While both Letybo and Botox use botulinum toxin type A to deliver smooth, refreshed skin, they have a few subtle differences that make each appealing:
- Onset & Duration: Both products generally last around 3 to 4 months. However, many patients notice Letybo’s full effects setting in slightly faster, often within 2 to 3 days compared to Botox’s typical 5 to 7 days
- Value: Because Letybo is newer to the U.S. market, it is often offered at a more competitive price point per unit than legacy brands like Botox. This provides a cost-effective option for maintaining regular treatment schedules without compromising quality
- Feel: Some patients report that Letybo leaves a lighter, softer finish that preserves natural facial movement while still softening deep frown lines
Who Might Consider Letybo
Letybo is worth a conversation for anyone who:
- Is looking for a temporary, non-surgical option for frown lines between the brows
- Wants to try a newer product with a substantial international track record
- Has experienced diminishing results from another neuromodulator over time and is curious whether a different formulation might respond differently
- Wants to explore a high-quality, budget-friendly alternative to traditional neuromodulators
