We all notice it eventually. Those lines between our eyebrows or on our forehead that won't go away, even when we aren't frowning. These dynamic wrinkles happen because our facial muscles move the same way thousands of times a day. At Kucumber Skin Lounge, we brought in Letybo because it's a game-changer from South Korea. Known as K-Tox, this treatment helps smooth wrinkles and soften frown lines while letting you keep your natural look.
Letybo is the newest FDA-approved neurotoxin used to smooth out moderate to severe frown lines in adults. It works by blocking nerve signals to the targeted muscles that cause you to squint or scowl. When these muscles take a temporary relaxation break, the skin on top finally gets a chance to flatten out, which hides those glabellar lines and deep facial wrinkles.

Most people use it for treating moderate to severe frown lines, but Letybo is a great non-surgical solution for the whole upper face.
Choosing Letybo injections is a smart move if you want a clean, high-quality product that you can trust.
If you want a youthful appearance without surgery, you’re likely a great fit. We’ll sit down for a personalized consultation to check your medical history and make sure it's safe for you.
We can't treat anyone with Letybo if they have pre-existing cardiovascular disease or have had an allergic reaction to a botulinum toxin before. If you have muscle weakness, trouble breathing, or difficulty swallowing, this isn't for you. Also, if you are pregnant, it’s best to wait.
When you come in for a Letybo treatment, it’s a very quick procedure. Your specialist will look at how your facial muscles move, then use a tiny needle for the Letybo injections. You might see a little mild redness at the injection site, but that usually goes away in a few hours. You won't need any required downtime, so you can head straight back to work or out to lunch.
You don't have to go home and rest after your visit. Just try not to do heavy muscle activity (like a gym workout) or lie down flat for about four hours. This helps the potency units stay right where we put them. You’ll see the wrinkles start to fade in a few days, and the full effect peaks at two weeks. To keep things looking smooth, most patients come back every three or four months.
Since 2010, our founders, Nadya Kozlova and Shay Sim, have focused on real skin health rather than chasing every seasonal trend. We’re actually the only med spa in the Pacific Northwest that runs its own internal training academy, meaning our injectors are mastering the art of facial anatomy.
As one of the few places in the PNW to offer Letybo, we vet every treatment ourselves to make sure they actually deliver the refined, natural results we’re known for. For us, the Kucumber standard means 20 years of clinical experience go into every single injection to ensure your facial movement remains fluid and natural. We look at your whole face to make sure your results look balanced, rested, and exactly like you.
The cost of Letybo depends on the actual work your face needs. Someone with deep, severe glabellar lines and thick muscles will need more work than someone just looking for a tiny touch-up on early signs of aging.
Giving a price without looking at your skin and how your face moves is just a guessing game, and we don't play those. During your personalized consultation, we’ll measure your muscle activity and give you a real, firm number.

Yes, they are both fda approved and work similarly. Letybo is the newest version, and many people think it feels a bit "lighter" on their face.
Definitely. It got fda approval after clinical studies with thousands of people. It’s a very safe non-surgical solution.
Tell us if you use anticholinergic agents or anything else for your nerves, as those can sometimes make muscle weakness worse.
Not at Kucumber. We focus on realistic expectations and natural facial movement so you can still express yourself.
Most patients see visible improvements for about three to four months before needing a touch-up.
