What does it treat?
Selected lines caused by facial muscle movement.
Common treatment areas include frown lines, forehead lines and crow’s feet. Approved areas vary by product.

Injectables • Botulinum toxin
Botulinum toxin injections temporarily relax selected facial muscles to soften expression lines, without surgery or adding volume beneath the skin.
What does it treat?
Selected lines caused by facial muscle movement.
Common treatment areas include frown lines, forehead lines and crow’s feet. Approved areas vary by product.
When will I see a change?
Changes develop over several days, rather than immediately.
The full effect may take about two weeks or longer, depending on the product and treatment.
Is there downtime?
Many people return to routine daily activities the same day.
Temporary bumps, redness or bruising can occur. Follow your treating team’s guidance about exercise and pressure on treated areas.
01 · Overview
Botulinum toxin blocks nerve signals to selected muscles for a limited time. Using small injections, a qualified clinician can reduce the muscle activity that creates certain expression lines. [1]
This treatment is different from dermal filler, which adds volume. It does not remove loose skin or reliably correct skin laxity. Lines visible even when your face is resting may soften less than lines that appear mainly with movement. [2]
Several botulinum toxin products are available. Their approved uses, dosing and timing differ, and their units are not interchangeable. Suitability depends on a surgeon consultation that considers your facial movement, health history and priorities. [1]
Treatment can be planned to preserve some movement, but the amount depends on your anatomy, dose and injection placement. Explain which expressions you want to keep and which lines bother you most.
It is not a skin-tightening treatment. Selective muscle relaxation may change the balance of facial movement, but it does not remove excess skin or replace a lifting procedure.
02 · Concerns & Goals
You may notice lines when you frown, smile or raise your eyebrows. Your consultation can help separate muscle-related lines from skin texture changes or looseness.
Lines between the eyebrows may become more noticeable when you concentrate or frown. Treatment targets the muscles contributing to that movement.
Horizontal lines appear as you raise your eyebrows. Planning needs to account for brow position and whether you use these muscles to help keep your eyes open.
Lines at the outer corners of the eyes often become more visible when you smile. Treatment should consider your smile and the surrounding muscles.
Creases present at rest, sun damage and skin looseness may need a different approach. Injections may address only the movement-related part of the concern.
03 · Options
A consultation should focus on the movement you want to change, not just a product name. These planning approaches may overlap.

Targets selected muscles between the eyebrows.
Softens horizontal forehead lines.
Addresses movement-related lines beside the eyes.
Plans more than one area together.
Ask which product is proposed, whether its planned use is FDA-approved or off-label, and why it fits your anatomy. Off-label use requires a clear discussion of the rationale, alternatives and risks. [1] [2].
No. Products differ in formulation, approved uses and dosing. A unit of one product should not be treated as equivalent to a unit of another, so unit prices alone are not a reliable comparison.
Your clinician may reassess after the effect has developed. Additional treatment is not always appropriate, and an early adjustment can make it harder to judge the final effect.
04 · Results
The effect builds rather than appearing at the appointment.
Movement and lines generally return as the effect fades.
Softer lines do not mean all creases or skin looseness will disappear.
Onset, duration and degree of change vary by product and person. Your clinician should explain the expected course for the specific treatment proposed. [1]
05 · Recovery
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery is usually brief, but your instructions should match the product, injection sites and health history. Returning to work does not mean every treatment effect has settled.
Step 1 · At the appointment
Your clinician reviews facial movement, cleans the skin and gives small injections. Brief stinging, redness or small raised spots may occur.
Step 2 · First day or two
Tenderness or bruising may be noticeable. Follow your team’s instructions about touching the area, positioning and exercise. Ask your surgical team whether compresses are appropriate and exactly how to use them.
Step 3 · Following days to about two weeks or longer
Muscle movement gradually decreases. Attend the recommended review rather than assuming an early uneven effect is the final result.
Step 4 · Over subsequent months
Movement gradually returns. Discuss whether to repeat treatment, change the plan or stop; ongoing treatment is a choice, not a requirement.
Use your treating team’s instructions rather than a general online timetable. Contact them if symptoms are worsening or unexpected.

Some asymmetry may be present before treatment or become noticeable as the effect develops. Contact your clinician for guidance and review. Do not massage the area in an attempt to correct it.
Avoid assuming an immediate, settled result. Ask your clinician how much time to allow for the chosen product, possible bruising and reassessment, especially if this is your first treatment.
06 · Safety
Brief stinging, small bumps, redness, tenderness or bruising can occur at injection sites. A headache is also possible. Symptoms should generally improve rather than worsen.
Injection sites may bruise, swell or feel sore. Infection is possible, though uncommon.
Unintended muscle relaxation can cause a lowered eyelid, heavy brow or change in brow position.
Asymmetry, an altered smile or more movement reduction than intended may occur and can last until the effect wears off.
Dryness, excessive tearing, blurred vision or double vision can occur and need clinical advice.
A serious allergic reaction is rare but requires urgent care, particularly with breathing difficulty or swelling of the face or throat.
Rarely, toxin effects can spread and cause generalized weakness or trouble speaking, swallowing or breathing. These symptoms require emergency assessment.
Discuss these risks and your individual health history with your surgeon. [1]
07 · Costs
Compare written estimates for the same planned scope: the product, treatment areas, proposed dose and follow-up arrangements. Different products’ units are not interchangeable.
Surgeon
For this nonsurgical treatment, this means the clinician’s assessment, treatment planning and injection care.
Ask your surgeonAsk whether consultation and treatment are billed separately and whether pricing is by area, unit or visit.
Facility
Treatment is generally office-based and often does not require anesthesia.
Ask your surgeonAsk whether any numbing option or facility charge is separate.
Supplies
The injectable product, treatment supplies and any included review visits.
Ask your surgeonConfirm the product, planned dose, review timing and whether additional injections carry a separate charge.
TRC
Any separately offered scheduling, education or care-coordination services.
Ask TRCAsk which services are optional, who provides them and whether they have a separate fee.
Your written estimate should explain the services included, any separate charges, and payment terms.
08 · Questions
No. Botulinum toxin reduces selected muscle activity. Dermal filler adds volume. They address different concerns and have different risks.
They do not reliably tighten loose skin. Your surgeon can assess whether movement, volume loss or excess skin is the main cause of your concern.
The effect gradually wears off and muscle movement returns. You do not need to continue treatment, and normal facial aging continues either way.
Choose a qualified, licensed medical clinician experienced in facial anatomy and botulinum toxin injections. Ask about product sourcing, emergency arrangements and follow-up, and avoid self-injection or products bought online.
