BOTOX® San Francisco


A pioneer in the use of  BOTOX® Cosmetic for cosmetic applications, San Francisco Botox® Cosmetic specialist Corey S. Maas, M.D., F.A.C.S. offers several facial injectable procedures at The Maas Clinic. With a board certification from the American Board of Facial Plastic and Reconstructive Surgery (ABFPRS), Dr. Maas is a leading innovator in minimally invasive techniques for facial rejuvenation.
BOTOX® Cosmetic – Medicinal and Cosmetic

Botox (“Botulinum A Toxin”), derived from the C. Botulinum bacteria, is a medicinal protein. For decades, BOTOX® Cosmetic has been considered a safe, effective treatment for conditions such as:

  • Eyelid spasms
  • Facial muscle imbalance
  • Neck muscle spasms

In recent years, BOTOX® Cosmetic has proven to be a successful cosmetic treatment as well. Dr. Maas, a San Francisco cosmetic surgery expert, helped to develop the techniques which are currently used to achieve optimal results from the cosmetic application of BOTOX® Cosmetic.

When BOTOX® Cosmetic is injected at the site of visible aging signs, the seemingly indelible creases between the brows, forehead, and eyes become smoothed and relaxed, creating a more rejuvenated facial appearance. For some of our patients in San Francisco, facelift surgery may be temporarily postponed due to the efficiency of BOTOX® Cosmetic and other cosmetic injectables.
