I received lip corner Botox treatment using Coretox. I revisited because I had my first lip corner Botox treatment with Liztox 4 months ago and the results were good. When I received it previously, the Botox effect was strong for about 1-2 weeks, so my lip movements felt unnatural when speaking, but it gets better over time. I plan to get a re-treatment in about 5 months after checking my condition. Both the staff member who guided me and the doctor were kind, and I am very satisfied that I was able to receive the treatment quickly right away without a long wait. Although there are many dermatology clinics near my home where I can get various treatments, places that offer lip corner Botox are limited, so I looked up many reviews before visiting.
