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.

Exceptional Talent, Timeless Results, and Unmatched Expertise! When it comes to aesthetics, excellence is everything, and I can confidently say that Carol is truly in a league of her own. Her expertise, artistry, and meticulous attention to detail are simply unparalleled. She has an extraordinary ability to enhance natural beauty while maintaining elegance, balance, and sophistication. Her results are consistently flawless, refreshed, and beautifully understated — the true definition of timeless beauty. What makes Carol exceptional is not only her remarkable skill but also her integrity, professionalism, and genuine dedication to her clients. She understands that the finest aesthetic work is never obvious; it is effortlessly beautiful. Two decades of loyalty speak for themselves. I trust her implicitly and would never consider putting my face in anyone else’s hands. She is the epitome of excellence in aesthetic medicine, and I cannot recommend her highly enough. An absolute five-star experience, every single time!

New update: I had a wonderful experience with Carol. She was professional, knowledgeable and paid attention to every detail to clearly explain my skin concerns. I’ll definitely be coming back! The moment I walked into the clinic I felt a happy, welcomed and professional setting. I had my Sofwave treatment with Alison Falada, Master Esthetician and Laser Specialist. She was nothing short of amazing! She was personable, knowledgeable, skilled and detailed throughout the entire experience. She took the time to thoroughly explain the entire process, addressed all of my my questions and concerns. Alison is an expert and provided great quality service! I love my results and can't wait to book my next appointment with her!
