InjectCo is 100% nurse-led. Every Jawline Slimming Botox appointment is handled by a trained nurse with physician oversight, so you are working with someone who understands both the clinical side of the treatment and the Colleyville community they serve.








Masseter Botox at InjectCo MedSpa Colleyville is priced by the unit.
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.
Most Colleyville patients want a number before they walk in. The honest answer is that your total depends on how large and how strong your masseter muscles are, which your nurse assesses in person. The calculator gives you a realistic range to plan around.
Pick your treatment areas and get an instant unit and cost estimate. It takes about a minute and gives you a realistic number to bring to your Colleyville assessment.

Masseter Botox is often planned alongside upper-face Botox, and sometimes with jawline filler when the width comes from bone or lost volume rather than muscle. Your nurse assesses which of those is actually driving the shape before recommending anything, because treating the wrong one will not change the result you want.
Your appointment starts with an assessment of your masseter muscles and lower-face anatomy. This helps your injector confirm that muscle size or overactivity is contributing to the concern before recommending treatment.
Patients treating a wide lower face often ask about Botox in Colleyville for the upper face at the same visit.
Traptox in Colleyville treats the trapezius for shoulder and neck tension, often booked alongside masseter work.
If the width comes from bone or volume rather than muscle, jawline fillers in Colleyville may be the better answer.
Full facial balancing in Colleyville plans the lower face alongside cheeks and chin rather than in isolation.

Botulinum toxin may slim the lower face when jaw width comes from enlarged masseter muscles. The muscle gradually reduces in size after its activity is lowered. It will not change the underlying jawbone.
No. Masseter Botox treats muscle-related width rather than loose skin. Reducing muscle size can make existing laxity more visible in some facial structures, so your provider should assess the skin and jaw before treatment.
It may reduce masseter activity, biting force, and pain associated with bruxism. Results vary, and the treatment does not address every cause of grinding. A dentist may recommend additional evaluation or a protective dental appliance.
Clenching-related effects may appear before visible jaw slimming. Changes commonly develop over two to six weeks and may last four to six months. Individual timing depends on the product, dose, muscle strength, and metabolism.
Proper placement aims to avoid the nearby muscles involved in smiling. Unwanted smile changes can occur if the product affects an adjacent muscle. This is one reason facial anatomy and injection placement matter.
Botulinum toxin has known risks, including pain at the injection site, unwanted weakness, asymmetry, and effects beyond the treated area. Masseter use is off-label, and repeated treatment may reduce chewing performance. A licensed medical provider should review the potential benefits and risks before treatment.
Cost should be evaluated by unit count rather than the total alone. At $12 per unit, $400 covers about 33 units, which may be below the stated 40-to-60-unit range for treating both sides. Your provider should explain the number of units included before you compare prices.
Masseter Botox reduces activity in a large jaw muscle. Filler adds volume or structure beneath the skin. A wide lower face caused by muscle may respond to Botox, while concerns involving lost volume or chin projection may require filler.
Botulinum toxin treatments at InjectCo MedSpa Colleyville are performed by licensed registered nurses under physician supervision. Masseter treatment is an off-label use of botulinum toxin.
Known risks include pain at the injection site, bruising, unwanted muscle weakness, asymmetry, and effects spreading beyond the treated area. Tell your provider about all medications, any neuromuscular condition, and any previous reaction to a neurotoxin. Treatment is not performed during pregnancy or breastfeeding.
Results vary between individuals depending on muscle size, strength, product selected and dose. Effects typically develop over two to six weeks and commonly last four to six months. Maintenance treatment is usually required.
Individual results vary. This treatment may not be suitable for everyone. Consult your medical provider.
