Popular, Proven Multi-Tasker

Widely acclaimed and overwhelmingly popular, BOTOX has become a staple of aesthetic medicine in the San Francisco Bay Area and beyond. It—or other neuromodulators such as Dysport®—is often the first treatment people try, prior to considering surgery. BOTOX is, in fact, a great way to enter the facial cosmetic world, as the results can be beautiful and the risks are minimal. The associates at Mabrie Facial Institute ensure that the men and women who visit our office truly understand what BOTOX can and cannot do, so that they can make educated choices. People visit MFI from the peninsula (Mountain View, Palo Alto, San Mateo), as well as the East Bay and cities throughout California and the U.S. for BOTOX.

The way neuromodulators like BOTOX work is surprisingly simple. They are made with a purified protein that, when injected into a targeted facial muscle, blocks the nerve impulses to that muscle. As a result, the muscle relaxes and the skin lies smooth, reducing the appearance of wrinkles.

How Much Does BOTOX Cost in the San Francisco Bay Area?

The price of BOTOX Cosmetic can range from $360 for a single treatment area to $1,200. The price is dependent on the amount of product used, the number of treatment areas, and the Injector. Prices are subject to change, so please call or check our Procedure Pricing page for current pricing.

How Long Does BOTOX Last?

Results appear in several days and will last about 3 months. You can maintain and improve upon the longevity of your results with regularly scheduled maintenance treatments.

How Many Units of BOTOX Will I Need?

You could need as little as 1 unit or as much as hundreds of units; it all depends on the concern being treated, the number of treatment areas, and other factors. This is a very common question, and while we cannot, with precision, determine how much product each patient will need for specific treatment concerns, we can provide a general estimate. Please refer to the graphic for average units per treatment area.

Combining BOTOX With Dermal Fillers

Many people discover that dermal fillers are better suited for their needs. While BOTOX improves wrinkles caused by the contraction of facial muscles, dermal fillers can improve a wider variety of wrinkles and creases, such as nasolabial folds (parentheses), smile lines, and lip lines. In addition to wrinkle reduction, dermal fillers may also be used for facial contouring. They can sculpt features such as the nose, cheeks, and lips. They can also fill in the area beneath the eyes, reducing dark circles. At MFI, we combine BOTOX and fillers in our Non Surgical Facelift package, often called a “liquid facelift.”

We specialize exclusively in non surgical facial rejuvenation and contouring and bring a fresh new perspective to non surgical options. We can recommend an injectable treatment for your specific goals.


Our Full Face 360° package is perfectly designed to help you look your absolute best. From the top of your forehead to your chin and jawline, your Wow-worthy results will help you feel confidently ready for anything (from any angle).

BOTOX Treatments Offered at MFI

BOTOX for Forehead & Brow

BOTOX Cosmetic reduces the appearance of signs of aging on the upper face, including:

  • Frowning Wrinkles: These are the vertical frown lines between the eyebrows that can etch a permanent frowning expression on your face. Our Injectors use BOTOX and Dysport to relax the 3 strong muscles that cause these glabellar lines.
  • Low Eyebrows: Many people are unaware that BOTOX can be used to create a subtle yet noticeable brow lift without surgery. Our injectors specialize in this “chemical brow lift” that can open up the eye area for women and men whose brows have begun to sag.
  • Forehead Wrinkles: When you elevate your brows, the skin on your forehead folds like an accordion. This can etch deep horizontal lines across your forehead, making you look older. We treat forehead wrinkles with a conservative approach since misuse of BOTOX in these muscles can cause the eyebrows to sag.
  • Crow’s Feet: Most people are familiar with crow’s feet—those branch-like lines at the outer corners of the eye. They are caused by repeated smiling and squinting, and are a hallmark of an aging face. BOTOX injections are a popular and effective choice for smoothing out this area, and some women start treatment in their late 20s or early 30s.

Our BOTOX for Forehead & Brow package is designed to address these concerns and leave you looking refreshed and more youthful.

Face Slimming BOTOX for Masseter & Jaw

Our BOTOX for Masseter & Jaw procedure is becoming a very popular treatment. It helps people achieve a v-shaped or v-line face by reducing fullness in the lower face caused by enlarged (hypertrophic) masseter muscles and/or parotid glands. BOTOX can be injected into masseter muscles, parotid glands, or both, for jawline reduction and to create a slimmer, more defined lower face, either with or without dermal fillers.

BOTOX for Excessive Armpit (Axillary) Sweating

Another popular use for BOTOX is the treatment of excessive sweating, a condition called hyperhidrosis. Many people suffer from this uncomfortable and embarrassing condition, caused by overactive sweat glands in the underarms. BOTOX injections can temporarily disable the glands, so you can feel confident (and dry) without resorting to expensive topical products or surgery.

BOTOX Recovery Period

The beauty of BOTOX is that it’s truly a “lunchtime treatment.” The process is quick, and you can return to your typical daily activities right away. You may have some redness and swelling at the injection sites, but we’ll help you soothe these with a cold pack. You can apply concealer after about 30 minutes which should hide any redness.

BOTOX Cosmetic FAQs

Are BOTOX injections safe?

When performed by an experienced medical professional (like all of our MFI Injectors), BOTOX is extremely safe. BOTOX has been used therapeutically for more than 30 years, and was approved by the FDA for cosmetic use in 2002. In the United States alone, millions of BOTOX injections have been performed, with only a relative handful of adverse effects, most of which were related to underlying medical conditions.

Does getting BOTOX hurt?

While BOTOX injections aren’t entirely pain-free, our patients find them very tolerable. The needle we use is very fine, and injections are shallow. Most people describe the sensation as comparable to an insect bite.

At what age should I start getting BOTOX?

That is a very personal decision, but one we’re happy to discuss at MFI. Some men and women wait until they are bothered by lines and wrinkles that won’t go away. This is commonly anytime from your late 30s to your 50s. Other individuals take a preventative approach and choose to start treatment in their 20s or early 30s.

Can BOTOX prevent wrinkles?

Yes, BOTOX can postpone or prevent the formation of wrinkles if treatment is started early. Women and men in their 20s and 30s have embraced BOTOX for its ability to delay the formation of dynamic wrinkles (those formed by repeated facial expressions). By preventing the movements that fold and crease the skin repeatedly, BOTOX can prevent dynamic wrinkles from setting in. Due to the smaller quantities used, this is often referred to as “micro-BOTOX” or “baby BOTOX.”

Will anyone be able to tell I’ve had BOTOX?

Ideal BOTOX results are detectable, but not obvious. You should look relaxed and refreshed, as if you’ve had a restful vacation. At MFI, we specialize in BOTOX treatments that produce natural-looking results. We like to say that people will notice, but no one will know.

Will my face look worse than before treatment if I stop getting BOTOX injections?

In a word, No! BOTOX works by blocking nerve signals to muscles that would normally tell those muscles to contract. When those muscles are not contracting the skin above lies smooth! BOTOX is temporary, lasting an average of 3 months, at this point, the muscles will slowly regain their ability to contract. If you discontinue treatment those dynamic wrinkles may reappear over time but your face should not look worse than before you began treatment.
