The first question we ask: is this line being created primarily by muscle movement?
When patients point to a line, we do not decide on Botox just because the line is visible. We first watch what happens when the face moves.
A forehead line that gets much stronger when someone raises their brows is different from a crease that is already deeply visible while the face is completely relaxed. The same is true between the brows and around the eyes.
We look at which muscles are creating the movement, how strongly they pull, how the brows sit at rest, whether there is already a static crease, and what the patient actually wants to preserve.
Sometimes Botox is the right tool. Sometimes it can soften the movement but cannot completely erase a line that has already become etched into the skin. And sometimes the concern is more about volume or skin quality than muscle movement. That is why we assess the cause before we talk about the unit count.
Clinical perspective approved by InjectCo's nurse injector team.
Chloe, RN is a Clinical Aesthetic Nurse Injector who treats patients at our FM 407 clinic. She is a Registered Nurse with a Bachelor of Science in Nursing from Chamberlain University. She also holds InjectCo's Advanced Aesthetic Injector Certification, earned through InjectCo's own Injector Training Academy, which is an internal training pathway rather than an independent board credential.
Cameron and Crystal are also nurse injectors here, and their full profiles are being added to our team page. Every injection is placed by a licensed nurse under a written protocol from our Medical Director, Dr. Josh Allen, D.O., and no injection is handed to unlicensed staff.
A dynamic line shows up when a muscle contracts and fades when the face relaxes. That is the kind of line Botox is designed to soften, because it works by reducing the movement behind it.
A line that stays visible at rest may have a static skin component, and it may not respond completely to neurotoxin alone. Static lines can reflect years of repeated movement, changes in skin quality and collagen, volume or structural change, or a mix of these. That does not automatically mean filler is the answer. It means the plan may need a different tool, more than one tool, or no treatment at all.
When volume is part of the picture, see dermal fillers in Argyle or full facial balancing in Argyle. Jawline fillers are a filler treatment, not a Botox one.
BOTOX Cosmetic contains onabotulinumtoxinA. It temporarily reduces the acetylcholine signal between targeted motor nerves and the muscles they control, so the treated muscle moves less. When repeated movement is creating a facial line, reducing that movement can soften how the line looks.
The prescribing information explains that the toxin interferes with acetylcholine release by cleaving SNAP-25, a protein the nerve ending needs to release that signal. Nothing is added under the skin and nothing is lifted, which is why Botox is a movement treatment rather than a volume treatment.
Botox is prescription-only and does not suit everyone, so read the risks and side effects before you book.
The BOTOX Cosmetic prescribing information lists a labeled dose for each approved area:
Your plan at InjectCo may use a different, individualized unit count depending on the area, your anatomy and your goal. That clinic estimate should not be confused with the product's FDA-labeled dosing, so ask your nurse how your plan compares with the labeled dose.
| Product | Active ingredient | FDA-approved for frown lines | Labeled frown-line dose | Onset in the label | Duration in the label |
|---|---|---|---|---|---|
| Botox | onabotulinumtoxinA | 2002 | 20 Units | Begins 1 to 2 days after injection, builds over the first week | About 3 to 4 months for frown lines |
| Dysport | abobotulinumtoxinA | 2009 | 50 Dysport Units | Not stated for frown lines | May last up to 4 months |
| Xeomin | incobotulinumtoxinA | 2011 | 20 Units | Median onset within 2 to 7 days | Typically up to 12 to 16 weeks, varies by patient |

Most side effects are temporary and tied to the injection or the treated area. They can include:
How often these happen depends on the area. In the label's frown-line studies, eyelid droop was reported in 3% of people treated. In the forehead-plus-frown-line studies, headache was reported in 9%, and eyelid droop, brow droop and skin tightness in 2% each. Those rates belong to those specific studies and are not universal rates for every area, dose or off-label use.
Boxed warning. Botulinum toxin products carry a boxed warning about the possible spread of toxin effect beyond the injection site. Symptoms such as difficulty swallowing, speaking or breathing need immediate medical attention. Full details are in the BOTOX Cosmetic prescribing information.
Contraindications on the FDA label. BOTOX Cosmetic should not be used if you have:
Warnings and precautions. People with certain neuromuscular disorders, such as myasthenia gravis, Lambert-Eaton syndrome or ALS, may be at increased risk of clinically significant effects from botulinum toxin. That is not an automatic no, but it calls for a careful medical review before any treatment decision.
Pregnancy and breastfeeding. Neither is listed as a contraindication, but the label reports no studies or adequate data in pregnant women and no data on breastfeeding. Tell your nurse if either applies, and elective cosmetic treatment is discussed with you individually before anything is planned.
Medicines. Mention any medicine that affects nerve-to-muscle signaling, such as aminoglycoside antibiotics or muscle relaxants, because the label says these can strengthen the toxin's effect. Blood thinners matter too, since they can make bruising more likely.
Botox works by reducing muscle activity. Using more product than the plan calls for can raise the chance of unwanted weakness or droop in nearby areas, the pattern described in the risks above. The goal is not the highest unit count. It is enough treatment to soften the intended movement while keeping the expression you want to keep.
That is also why we ask what you like about your face in motion, not just what you want gone.
Two results from one patient, each photographed with the same expression before and after treatment, so you are comparing movement with movement rather than a relaxed face with a tense one.

InjectCo MedSpa Argyle is at 2660 FM 407 E, Suite 100, inside the Cloud 9 Salon and Spa building beside Bartonville Town Center. Marty B's is in the same building complex, a handy marker the first time you visit.
Why the Bartonville address? The clinic carries the Argyle name because it serves Argyle, Lantana and the surrounding towns of southern Denton County, but the building itself sits in Bartonville, so maps and our listing show Bartonville, TX 76226.
Getting here. FM 407 is the road in from every direction. From Argyle Town Hall it is about 4.8 miles east. From I-35W or US-377, take FM 407 east for about 5.8 or 4.3 miles. Lantana Town Center and its Kroger Marketplace sit 1.3 miles south on FM 407, about three minutes away.
Botox is $12 per unit at InjectCo MedSpa Argyle. Your total depends on how many units your plan needs, which your nurse sets after assessing your movement, history and goals. The plan and expected price are reviewed with you before treatment. Our Botox cost guide for Texas explains how totals are worked out.
The clinic is branded for Argyle because it serves Argyle, Lantana and nearby towns, but its street address is 2660 FM 407 E, Suite 100, Bartonville, TX 76226, inside the Cloud 9 building. It is the same clinic either way.
Yes. InjectCo MedSpa was previously known as The Botox Bar, and this clinic's Google profile carried that name before it became InjectCo MedSpa Argyle. Older Google reviews for the clinic still mention The Botox Bar.
Lantana Town Center and its Kroger Marketplace are 1.3 miles south on FM 407, about three minutes away, and the Lantana Community Event Center is about 2.4 miles away. From Flower Mound Town Hall it is about 7.4 miles, roughly 18 minutes in weekday morning traffic. The drive-times section on this page lists 17 nearby towns.
Chloe, RN, a Clinical Aesthetic Nurse Injector with a Bachelor of Science in Nursing from Chamberlain University, treats patients at the Argyle clinic along with nurse injectors Cameron and Crystal, whose full profiles are being added to our team page. All three work under the oversight of our Medical Director, Josh Allen, D.O.
Your nurse watches the area at rest and in motion, checks how strongly the muscle pulls, reviews your treatment history and asks how much movement you want to keep. The unit count comes after that assessment, not before it.
No. The BOTOX Cosmetic label lists 20 Units for frown lines alone, 24 Units for crow's feet and 40 Units total for forehead lines treated with frown lines. A clinic range, including figures like 20 to 25 units, is a clinical estimate for a specific plan, not FDA-labeled dosing.
Four areas in adults: frown lines (the first cosmetic approval, in 2002), crow's feet, forehead lines and vertical neck bands (approved in 2024). Other areas are off-label.
Off-label use means the medication is FDA-approved, but the FDA has not approved that specific treatment area or use. Bunny lines, a lip flip and chin dimpling are examples. Your nurse names an off-label area before planning it, and you can decide from there. More on the Botox lip flip in Argyle.
No. Each product has its own unit scale. Dysport's label states that its units cannot be converted into those of any other botulinum toxin, and Botox units are product-specific in the same way. Your nurse quotes each product on its own terms.
Most side effects are temporary, and botulinum toxin products carry a boxed warning about possible spread of toxin effect beyond the injection site. Trouble swallowing, speaking or breathing needs immediate medical care. See the full risks section.
A contraindication is a situation where the label says the product should not be used, such as a known allergy to a botulinum toxin product or an infection at the injection site. A precaution flags a situation that needs extra review and may change the decision, such as certain neuromuscular disorders.
Call the clinic once it has had about two weeks to settle. Your nurse reviews your movement and symmetry before deciding whether an adjustment is appropriate. Extra units are not added automatically.
Use the Texas Board of Nursing license verification for nurses and the Texas Medical Board license lookup for physicians. Both are free public tools.
At $12 a unit, $400 covers about 33 units. Whether that matches your plan depends on the areas and your assessment, so treat it as a budget figure, not a dose. Our Botox dosage guide explains how unit counts vary by area.
For frown lines, the label puts the typical effect at about three to four months and notes that dosing more often than every three months has not been studied. Timing varies between people, and your previous treatment history and response can shape your next plan. Our guide to how long Botox lasts covers the full timeline.
Approved patients can begin treatment the same day and pay over time instead of all at once.
How it works: apply online with CareCredit or Cherry in a few minutes, get a decision on the spot, then bring your approval to your appointment. Our team can help you compare options during your consultation and apply on the day if you prefer.
Terms and rates are set by the financing provider. Your nurse will walk you through your total cost, including any financing fee, before anything is booked.
A Botox appointment squeezed into the first open slot, with no real look at how you move, is the one most likely to need a correction.
Product facts on this page come from FDA labeling on DailyMed:
Texas delegation rules. Texas treats the cosmetic injection of medications as the practice of medicine. The Texas Medical Board's rules in 22 Texas Administrative Code Chapter 169 (sections 169.25 to 169.28, effective January 9, 2025) allow a physician to delegate it only under that chapter's delegation, supervision and notice requirements. For how those rules apply to nurses, see can nurses do Botox independently.
