What is
K-Tox Letybo?

Looking for a gentle, effective way to smooth fine lines and wrinkles? Meet Letybo, also known as “K-Tox”, the newest injectable neurotoxin. Korea’s number 1 neurotoxin is now available at Chicago Aesthetics Surgery & Med Spa. K-Tox offers natural-looking results with minimal downtime, making it the perfect alternative to traditional botulinum injections.

K-Tox is a Korean-made neuromodulator similar to Botox, used to temporarily relax facial muscles that cause wrinkles and fine lines. The active ingredient in K-Tox is botulinum toxin type A, the same used in other popular injectables, but Letybo is uniquely formulated for precision, purity, and a smooth, soft finish.

Known for its lightweight feel and refined outcome, K-Tox is ideal for patients who want subtle, refreshed, and more youthful-looking skin.

Benefits Of
K-Tox

  • Smooths fine lines and wrinkles on the forehead, around the eyes (crow’s feet), and between the brows
  • Delivers a soft, natural expression — never frozen or overdone
  • Minimally invasive with no downtime
  • Fast-acting with visible results in just a few days
  • Great for first-time users or those who want a gentler wrinkle relaxer
  • #1 Korean beauty treatment now available in the U.S.

What Is The Difference Between K-Tox and Botox?

While K-Tox and Botox use the same active ingredient (botulinum toxin A), K-Tox (Letybo) is manufactured in Korea using a highly purified formula that many patients report feels lighter and more refined. It’s one of the top beauty treatments in Korea and is now FDA-approved for use in the U.S.

I had Lipo 360 and a Skinny BBL this summer, and I am so happy with my results. I was always extremely nervous about going under the knife, but I really wanted to do something that would help boost my self-confidence. Dr. T and his entire team were truly amazing throughout the whole process. I am naturally pretty skinny, so I was always worried about whether this procedure would work well for my body type, but I honestly wish I had done it sooner. I am currently about five weeks post-op, and I am already so pleased with how everything is turning out. My results continue to improve as I heal, and I’m excited to see the final outcome. I’m very grateful to Dr. T and his team for making me feel comfortable and confident throughout the experience.

Nurse Carol always does an outstanding job no matter the procedure. She literally has light hands and you barely feel a thing. She brightens my day whenever I have an appointment with her. Very kind, professional and very knowledgeable. I have never had anyone as thorough as her. She communicates with me before and after all appointments and reaches out to ensure I safely drive there sooner due to the weather conditions. ⭐⭐⭐⭐⭐ I cannot say enough wonderful things about Nurse Carol Donohue. After four years as her client, I can genuinely say that the trust, care, and relationship we have built over the years means so much to me. Carol has always been incredibly easy to communicate with and accommodating with my schedule. She consistently goes above and beyond for her clients—even coming in early before her shift to make sure she can see me when needed. That level of dedication and care does not go unnoticed. What I appreciate most about Carol is her integrity. She doesn’t simply recommend a cosmetic procedure because she can perform it. She takes the time to honestly tell me what would be beneficial, what may be unnecessary, and what she believes is best for me. My health, well-being, and safety have always come first, and that has given me an incredible amount of confidence and trust in her. Carol is knowledgeable, professional, friendly, and genuinely welcoming. She explains everything in detail, makes sure I understand every step of the process, and always makes me feel comfortable and cared for. She values her clients as people, not just appointments. Beyond her professionalism, Carol’s kindness has touched me personally. There have been days when I walked into her office feeling at my lowest, and simply being met with her warmth, compassion, and kindness helped me leave feeling a little more confident and a lot better than when I arrived. That is something I will never forget. Thank you, Nurse Carol Donohue, for four wonderful years of professionalism, honesty, compassion, and exceptional care. I am incredibly grateful for the client-and-nurse relationship we have built, and I look forward to many more years to come. I wholeheartedly recommend her to anyone looking for a provider who combines expertise with integrity and truly cares about the people she serves.

I’ve been getting Botox from Carol for several years now, and I couldn’t be happier with my experience! She is incredibly kind, knowledgeable, and professional, and she always takes the time to make sure I feel comfortable and confident throughout the process. I truly trust her expertise and appreciate how carefully she listens to what I want while providing honest, thoughtful recommendations. My results have always looked natural and beautiful, which is exactly what I’m looking for. I highly recommend her to anyone considering Botox or looking for someone skilled, trustworthy, and genuinely caring!

Wasn’t sure what I needed to fill up my cheeks after 85lbs weight loss so I decided to visit Carol Donohue for her expertise. We decided to go with sculptura treatment and she made it virtually pain free. I see improvement but most of it from the bac water injection. Glad I found her Will post update after 4 weeks
