Botox, Dysport & Daxxify in Petaluma & Hercules

Understanding Neurotoxin Treatments

Botox, Dysport, and Daxxify are FDA-approved neurotoxin treatments that have dramatically changed how we treat unwanted frown lines and dynamic wrinkles. These injectable treatments work by temporarily relaxing facial muscles that cause skin wrinkles, the lines that form from repeated expressions like frowning, squinting, and smiling. At Dermatology Associates of the Bay Area, our board-certified dermatologists have over 20 years of experience with neurotoxin injections, combining medical precision with an artistic eye to deliver natural-looking results that help you look refreshed and relaxed.

How Neurotoxins Work

Neurotoxin treatments work by blocking nerve signals to targeted facial muscles, preventing them from contracting and forming wrinkles. The benefits include relaxing overactive muscles that cause expression lines, smoothing existing wrinkles by preventing repetitive muscle movement, preventing new wrinkles from forming or deepening over time, and providing natural-looking results when administered with the proper technique.

The effects are temporary, typically lasting 3-6 months, allowing for adjustments and refinements over time. This temporary nature also means results look natural. You’ll still be able to make expressions, but without the deep creases and lines.

The Treatment Experience

During your personalized consultation, our dermatologists assess your facial anatomy and muscle movement patterns, discuss your aesthetic goals and expectations, review your medical history, and create a customized treatment plan with appropriate dosing.

The injection process typically takes 15-30 minutes. We use ultra-fine needles with strategic injection points based on your unique facial anatomy. You can return to normal activities immediately after treatment.

Results develop gradually over time. Initial effects may become noticeable within 2-3 days, especially with Dysport. More pronounced results are visible at 5-7 days for Botox and Daxxify. Full results are achieved at two weeks across all neurotoxins, with gradual return of muscle movement occurring over 3-6 months, varying by product.

Neurotoxin Treatment

Frequently Asked Questions

What’s the difference between Botox, Dysport, and Daxxify?

While all three are neurotoxins that work similarly, they differ in onset time and duration. Dysport often works faster (2-3 days), Botox is the most extensively studied with proven results, and Daxxify lasts longer (up to 6 months). Our dermatologists will help you choose the best option for your needs.

How long do results last?

Botox and Dysport typically last 3-4 months, while Daxxify can last up to 6 months. Results vary by individual factors, including metabolism, muscle strength, and injection technique. Regular treatments help maintain smooth, youthful-looking skin.

Will I look frozen or unnatural?

When administered by experienced dermatologists using proper technique and conservative dosing, neurotoxin treatments should look natural. You’ll maintain facial expressions while smoothing unwanted wrinkles. The goal is to look refreshed and relaxed, not frozen.

What should I avoid before and after treatment?

Before treatment, avoid blood-thinning medications and supplements like aspirin, ibuprofen, and fish oil for one week. After treatment, avoid lying down for 4 hours, vigorous exercise for 24 hours, and facial massage for one week.

Can neurotoxins be combined with other treatments?

Absolutely! Neurotoxin treatments combine beautifully with dermal fillers, laser therapy, chemical peels, and other aesthetic procedures. Our dermatologists often create comprehensive treatment plans addressing multiple aging concerns simultaneously.

How often should I get treatments?

Most patients schedule treatments every 3-4 months for Botox and Dysport, or every 4-6 months for Daxxify. Regular treatments help prevent new wrinkles from forming and may extend the time between sessions.

Is there any downtime?

There’s essentially no downtime with neurotoxin treatments. You may experience minor redness or bruising. Most patients return to work and normal activities immediately.

Can men benefit from neurotoxin treatments?

Yes! Men increasingly seek neurotoxin treatments for a more refreshed, professional appearance. Our dermatologists adjust injection techniques and dosing to maintain masculine facial characteristics while smoothing wrinkles and preventing aging.
