A complete guide to how neurotoxin treatments work, what to expect, and how to make an informed decision about your care.

The science
Understanding what happens beneath the surface helps you set realistic expectations and have a better conversation with your provider.
Botox, and its close relatives, are all derived from botulinum toxin type A — a purified protein produced by the bacterium Clostridium botulinum. In aesthetic medicine, it's used in tiny, highly controlled doses that are a fraction of what would be considered pharmacologically significant.
Facial wrinkles are grouped into two types. Static wrinkles are visible even at rest — caused by volume loss, sun damage, and skin aging. Dynamic wrinkles form from repeated muscle movement: squinting, frowning, raising your eyebrows. Neurotoxins target only dynamic wrinkles.
When injected into a specific muscle, the toxin blocks the release of acetylcholine — the neurotransmitter that tells muscles to contract. Without that signal, the muscle relaxes, and the skin above it smooths. The muscle itself is not damaged; the effect is temporary and fully reversible as the nerve endings regenerate over time.
Results begin to appear within 3 to 5 days as the neurotoxin binds to nerve terminals, with the full effect visible at the two-week mark. Most clients return for touch-up assessments at this point. Over several months, as nerve regeneration occurs, muscle movement gradually returns — at which point repeat treatment can maintain results.
Consistent treatment over time has a secondary benefit: because the muscles are used less frequently, the skin above them gets a break from repeated creasing, which can slow the deepening of lines over the long term.
The process
A typical Botox session at The Park MedSpa takes 20 to 30 minutes from start to finish. Here's exactly what that looks like.
Before any treatment, we talk through your aesthetic goals, review your medical history, and discuss any medications or conditions that may be relevant. No commitment is required at this stage — it's purely informational.
Your provider examines your facial anatomy at rest and in motion — watching how your muscles move, where lines appear, and assessing skin quality. This determines the precise injection sites and dosage per area. No two faces are treated identically.
Using an ultra-fine needle, your provider places small amounts of neuromodulator into the targeted muscles. Most clients describe the sensation as a brief pinch. Topical numbing cream is available if preferred. The treatment step typically takes 5 to 10 minutes.
Your provider walks you through aftercare instructions: what to avoid for the first 24 hours, what to expect over the following two weeks, and how to reach us with any questions. A follow-up is scheduled at the two-week mark.
Treatment areas
Neuromodulators work on any area where repeated muscle movement creates visible lines. Discuss specifics with your provider at your consultation.
Horizontal lines caused by raising the brows. Botox relaxes the frontalis muscle. Dosing here requires balance — overtreating can cause brow heaviness, which is why assessment of your natural brow position matters.
The vertical furrows between the brows formed by frowning. Relaxing the corrugator and procerus muscles creates a more open appearance without removing expression.
The fan-shaped lines at the outer corners of the eyes from squinting and smiling. Treated by relaxing the orbicularis oculi muscle. Results here tend to be particularly natural-looking.
By relaxing the depressor muscles that pull the brow downward, the elevator muscles gain a subtle advantage — lifting the brow position by 1 to 2mm without surgery.
A few units along the upper lip relax the orbicularis oris outward, giving the appearance of a slightly fuller lip. Also used for vertical lip lines caused by repeated pursing.
Injecting into the masseter muscles reduces their bulk over time. Used for jaw slimming, softening a square jawline, or reducing teeth grinding (bruxism). Results develop gradually over 4 to 6 weeks.
Visible vertical cords in the neck caused by the platysma muscle. Strategic placement relaxes them and can subtly lift the lower face — a technique known as the Nefertiti lift.
Botox blocks nerve signals that trigger sweat glands. Injected into underarms, palms, or feet, it can dramatically reduce excessive sweating. Results typically last 6 to 12 months.
Bunny lines appear across the nose bridge when scrunching. Chin dimpling is caused by the mentalis muscle. Both respond well to small, precise amounts of neurotoxin.
Am I a good candidate?
Neurotoxins are among the safest aesthetic treatments available, but there are meaningful differences in candidacy. A thorough consultation helps determine what's right for you.
Aftercare & recovery
Neurotoxin aftercare is minimal — but following a few guidelines in the first day helps ensure the treatment settles exactly where it was placed.
Frequently asked
When administered by a trained medical professional in appropriate doses, botulinum toxin has an extensive safety record spanning over 30 years of clinical use. Common side effects are mild and temporary: slight bruising or redness at injection sites, minor headache in the first 24 hours, or brief tenderness. Rare complications such as eyelid drooping or asymmetry are typically the result of placement error and can be corrected. All injections at The Park MedSpa are performed under the clinical oversight of Dr. Art Miller, MD.
Most clients describe the sensation as a brief pinch — comparable to a small insect bite — that lasts less than a second per injection point. The needles used are extremely fine. If you're particularly sensitive, topical numbing cream can be applied 20 to 30 minutes before treatment. Post-treatment soreness, if any, typically resolves within a few hours.
The "frozen" look results from excessive dosing, not from the treatment itself. At The Park MedSpa, our philosophy is to enhance — not erase. We use conservative, targeted amounts designed to soften dynamic lines while preserving the full range of facial expression. A skilled injector treats specific muscles without affecting surrounding ones, so you still smile, frown, and raise your eyebrows naturally.
These are two distinct types of injectables addressing different concerns. Neuromodulators (Botox, Dysport, Xeomin, Jeuveau) relax muscles to soften expression lines — they don't add volume. Dermal fillers restore or add volume by filling space beneath the skin. Many clients benefit from both. Your provider will recommend what fits your goals at your consultation.
There is no physical dependence. If you stop treatments, muscle movement returns gradually over 3 to 6 months and lines return to where they were — possibly less deep if you've been preventing them from forming. Some clients continue because they prefer their results; others use it seasonally. It's entirely your choice, with no medical consequence either way.
There's no universal right age. The appropriate time depends on when dynamic lines become noticeable to you, your level of facial movement, your skin type, and your personal goals. Some clients start in their late twenties for preventative purposes. Others first come in their 40s, 50s, or later, and see excellent results. A consultation is the best way to assess what makes sense for your face right now.
Yes — and it's common. Neurotoxins are often combined with dermal fillers for more comprehensive rejuvenation, with chemical peels like the VI Peel for improved skin texture, or with energy-based devices like Morpheus8 for skin tightening. The sequencing and spacing of treatments matters for safety and results, which is why a personalized plan from your provider is important.
