Botox Q & A

What is Botox?

Neuromodulators are wrinkle-relaxing injections of botulinum toxin, commercially known as Xeomin, Botox, Dysport, and Daxxify. They can reduce the appearance of facial creases and wrinkles by relaxing specific muscles.

Dr. Zand uses them to soften frown lines, forehead lines, and crow’s feet. She can also use neuromodulators to help with chronic migraines, temporomandibular joint dysfunction (TMJ), uncontrolled blinking, and excessive sweating in the palms or underarms.

How is a Botox treatment performed?

First, Dr. Zand asks you to make exaggerated facial movements so she can identify the areas that treatment would most improve. She takes extra measures to avoid the muscles necessary for natural expressions so that you won't look “frozen.”

Dr. Zand uses the tiniest needles possible, so the treatment is mostly painless, similar to acupuncture. No anesthetic is required, and the procedure only takes a few minutes. However, Dr. Zand also offers numbing cream in case you feel nervous.

You will notice a change about three days after treatment, and it takes about two weeks to see maximum results. Potential side effects include temporary bruising and a slight headache after treatment, but that’s rare.




How long does Botox last?

The effects of Xeomin, Botox, and Dysport last about four months. After repeated treatments, your muscles are trained to relax, and your wrinkles remain less severe. Thus, less medicine is needed to achieve the same result over time.

Is Botox right for me?

Botox does not help to fill in existing wrinkles that have already formed; instead, it prevents your muscles from continuing to make those lines. As a result, it’s unlikely that wrinkles caused by sun damage or gravity would achieve complete resolution with neuromodulators alone (luckily, Dr. Zand can combine it with fillers to correct deep-set wrinkles).

Neuromodulators are the best treatment available to soften the wrinkles on the forehead and around the eyes. The earlier you start — ideally mid-30s and early-40s — the easier it is to maintain beautiful and natural results.

If you feel nervous about injecting a “toxin” into your skin, take comfort in the fact that researchers haven't discovered any long-term side effects in the 25 years since doctors first started using Botox.

The most prominent “side effect” Dr. Zand sees is that her patients fall in love with the result and get hooked on Botox. “I wish I had started sooner,” is the typical reaction she hears from initially-nervous patients.

If you’re pregnant, breastfeeding, suffer from a neurological disorder, or are allergic to albumin, Dr. Zand doesn't recommend getting Botox.

Combining Botox with aesthetic filler treatments and a healthy lifestyle can have your skin feeling 10 years younger in no time. Call Dr. Zand or schedule an appointment online to discuss your cosmetic treatment options and age gracefully.

  • "I had a wonderful experience at Zand Dermatology for first-time Botox, specifically seeing Lexi. I was a little nervous about the procedure, but Lexi immediately put me at ease -- she asked lots of questions and ensured she understood why I was there/what I wanted, then very patiently walked me through various options and amounts and what I could expect with each. (Totally validating my feeling that this was the kind of experience you should come to a professional for.) The whole thing was completely painless and I am so so happy with the results."

    "I've been seeing cosmetic dermatologists for the past 30 years and Dr. Zand is the only person I trust to do my treatments. Her attention to detail is like no other and her outcomes are exquisite." 


    "The BEST Botox injections you will ever get! I've gone to many Med Spas for Botox and never saw results as good as I did from Dr. Zand and her team. They are meticulous with placement of injection and honest about the amount of units needed to provide the best results. Dr. Zand is exceedingly knowledgeable in not just Botox and fillers, but everything related to the overall health of your skin. Since this is my face we're talking about, I'm tired of wasting money on bad Botox injections and fillers at other places. I want it done right, so this is where I go."
