I visited the Maypure Gangnam branch and received a Botox treatment using Coretox. I think Maypure is the best because the Botox prices are reasonable. I got the temporalis muscle Botox because I had a problem clenching my teeth while sleeping, and since I have been seeing consistent results, I am getting it regularly. I usually get Coretox or Xeomin because I am worried about developing resistance; since Coretox is twice as cheap, I chose Coretox this time. After the Botox treatment, I can't feel the tension in my temples and temporalis muscles, so I no longer grind my teeth while sleeping, which is amazing. I used to suffer from headaches constantly, but those have completely disappeared. If you have severe migraines, give Botox a try. You will see the light.
