Understanding BOTOX & Dysport: FDA-Approved Neuromodulators
Both BOTOX and Dysport are FDA-approved injectable treatments derived from botulinum toxin type A, a purified protein that temporarily relaxes targeted facial muscles responsible for dynamic wrinkles. According to the American Society of Plastic Surgeons, BOTOX remains the most popular non-surgical cosmetic procedure in the United States, with almost 10 million treatments performed

time.
The result is a smoother, more youthful appearance while maintaining natural facial expressions and movement.

Key Differences Between BOTOX and Dysport
While both treatments utilize botulinum toxin type A, they differ in their molecular structure and diffusion patterns:
BOTOX: More concentrated formulation with precise targeting capabilities
Dysport: Broader diffusion pattern, ideal for treating larger areas like the forehead
Onset: Dysport may show results 2-3 days earlier than BOTOX
Duration: Both typically last 3-4 months, though individual results may vary
Treatment Areas and Applications
Primary Treatment Areas
Forehead Lines: Horizontal lines across the forehead caused by raising the eyebrows are effectively smoothed with strategic neuromodulator placement.
Frown Lines: The vertical lines between the eyebrows, also known as glabellar lines, respond exceptionally well to both BOTOX and Dysport treatments.
Crow’s Feet: Fine lines radiating from the outer corners of the eyes are softened while preserving natural smile expressions.
Additional & Advanced Treatment Areas
In addition to classic wrinkle treatment, BOTOX and Dysport may be used in several advanced applications when performed by experienced injectors with a deep understanding of facial anatomy:
Brow Lift Effect: Strategic injection patterns can create a subtle lifting effect, helping alleviate heavy brows and lids and providing a more rested

opening the eye area without surgery.
Bunny Lines: Fine lines that appear on the nose when smiling can be addressed with precise neuromodulator placement.
LLSAN for Gummy Smile: A few units in this muscle can reduce gum show by lowering the upper lip. This can also be combined with a lip flip.
Lip Lines: Vertical upper lip lines (also known as “smokers’ lines” or “barcode lines”) around the mouth benefit from careful treatment that maintains natural lip movement.
Lip Flip for Gummy Smile: A few units placed above the upper lip can relax muscle pull, reducing gum show and enhancing balance in the smile.
DAO (Corners of the Mouth): Treating the depressor anguli oris (DAO) muscles can reduce downward pull at the corners of the mouth, creating a more relaxed, balanced expression.
Masseter (Jawline Slimming): Neuromodulator treatment of the masseter muscles may help soften a square jawline and can also be beneficial for patients who clench or grind their teeth.

Combination Treatments
Neuromodulators work synergistically with other non-surgical cosmetic treatments to provide comprehensive facial rejuvenation:
Dermal Fillers
While BOTOX and Dysport address dynamic wrinkles, dermal fillers like Restylane and Juvederm restore volume and smooth static lines.
Laser Treatments
Combining neuromodulators with laser resurfacing like Clear + Brilliant® addresses both muscle-related wrinkles and concerns related to skin texture.
Microneedling
Microneedling treatments complement neuromodulators by stimulating collagen production and improving skin texture, helping enhance overall skin quality while wrinkle relaxers address facial muscle activity.
Facial Rejuvenation Procedures
For patients seeking more comprehensive results, neuromodulators can complement surgical procedures such as facelifts, eyelid lifts, or brow lifts.

Frequently Asked Questions About BOTOX
BOTOX and Dysport are wrinkle relaxers that work by temporarily reducing muscle activity, softening facial wrinkles, creases, and facial lines. Both treatments use a purified neurotoxin (botulinum toxin type A) that blocks nerve signals to targeted muscles, preventing repetitive movements that cause lines to form. Over time, this not only smooths existing wrinkles but may also help preserve collagen by reducing stress on the skin, keeping it looking smoother and more youthful.
Dr. Karen Horton’s Plastic Surgery office, conveniently located at 2100 Webster Street, Suite 520 in San Francisco, offers both BOTOX and Dysport treatments performed by Board-Certified Nurse Practitioners. Their expertise and artistic approach ensures natural-looking results that enhance your unique facial features while maintaining your ability to express emotions naturally.
Most patients benefit from treatments every 3 to 4 months to maintain optimal results. However, some individuals may find their results last longer with regular treatments, as the muscles gradually become trained to contract less forcefully. During your consultation, your provider will determine the best treatment plan for your specific needs.
While pricing can vary, both treatments are typically priced per unit, with Dysport generally requiring more units due to its different concentration. During your consultation, we will discuss the most cost-effective approach for your specific treatment goals.
Your first visit will include a comprehensive consultation, during which your Nurse Practitioner will evaluate your facial anatomy and discuss your goals. The actual treatment takes 15-30 minutes, with most patients experiencing only mild discomfort. You’ll receive detailed aftercare instructions and can typically return to normal activities immediately.
