What Botox® Treats
As one of the most popular and widely requested procedures in the United States, BOTOX® is a non-surgical solution that rejuvenates the face, restoring a more youthful and smooth appearance. BOTOX® is designed to treat the common signs of aging that appear on the face, including:
- Masseter hypertrophy
- Crow’s feet
- Frown lines
- Fine lines
- Unwanted lines and wrinkles can be caused by smiling, frowning, squinting or even chewing!

What to Expect from Your Botox® Treatment?
BOTOX® or Botulinum Toxin is a purified substance that is designed to block muscle nerve signals, weakening the underlying muscles of the face. Results from BOTOX® are not permanent and wrinkle-causing muscles will eventually begin to contract again. Additional procedures will be necessary to block nerve signals to the muscles. Results typically last 6-9 months, depending on the individual anatomy of the patient.
Skin Quality Between Treatments
After years of treating facial aging, I continue to see how strongly skin quality influences how beautifully results hold between appointments.
That clinical observation is one reason I developed physician-formulated skincare designed to support skin with the same discipline I bring to treatment.
