Botulinum toxin (Botox) injections may be performed for cosmetic purposes, such as treatment of forehead lines and wrinkles, or for therapeutic purposes, such as treatment of jaw clenching, teeth grinding (bruxism), myofascial pain, jaw tension, or tension-related headaches. Although the treatment areas differ, the aftercare advice is largely the same.
What to Expect After Botox Treatment
Botulinum toxin does not work immediately. Most patients notice the first effects within 3-5 days, with the full effect developing over approximately 10-14 days.
Depending on the treatment area, you may notice:
- Softening of facial lines and wrinkles
- Reduced jaw clenching or grinding
- Reduced muscle tension
- Less jaw pain or facial fatigue
- Improvement in tension-type headaches
- Reduced tooth wear caused by excessive muscle activity
The effects are temporary and typically last 3-6 months, although this varies between individuals.
Immediately After Treatment
Small red marks at the injection sites are common and usually settle within a few hours.
Mild tenderness, swelling, or bruising may occur and generally resolves within a few days.
Most patients are able to return to work and normal daily activities immediately after treatment.
How to Reduce Bruising After Botox
Although bruising cannot always be prevented, the following measures may reduce the risk:
- Apply a cold compress gently to the treated area for short periods if advised by your clinician
- Avoid vigorous exercise on the day of treatment
- Avoid alcohol for 24 hours after treatment
- Avoid rubbing or massaging the treated areas
- Sleep with your head slightly elevated on the first night if facial swelling is present
Minor bruising usually settles spontaneously within 1-2 weeks and may be concealed with make-up after the injection sites have closed.
The First 4 Hours After Botox
For the first 4 hours after treatment:
- Remain upright
- Avoid lying flat
- Avoid prolonged bending forwards
These precautions are intended to minimise unwanted spread of the medication.
The First 24 Hours After Botox
For the first 24 hours, avoid:
- Rubbing or massaging the treated areas
- Facials or facial massage
- Excessive pressure on the injection sites
- Vigorous exercise
- Saunas, steam rooms, and hot yoga
- Excessive alcohol consumption
Normal washing, showering, and skincare routines may usually continue, provided the treated areas are handled gently.
Aftercare Following Cosmetic Botox
If you have undergone cosmetic Botox treatment to areas such as the forehead, frown lines, crow’s feet, bunny lines, or neck, you may notice a gradual reduction in muscle movement over the following 1-2 weeks.
During this period the area may feel slightly different, tighter, or heavier than usual. This is normal and usually settles as the treatment reaches its full effect.
It is important not to judge the final result too early. Most patients do not see the completed result until approximately 2 weeks after treatment.
Aftercare Following Masseter & Temporalis Botox
Masseter and temporalis Botox is commonly used for:
- Temporomandibular dysfunction (TMD)
- Teeth grinding (bruxism)-related symptoms
- Jaw clenching
- Myofascial pain
- Tension headaches
- Jaw muscle enlargement (masseter hypertrophy)
Improvement is usual gradual. As the treatment takes effect, you may notice:
- Reduced clenching force
- Less facial muscle fatigue
- Reduced jaw tension
- Improvement in facial pain and discomfort
Some patients notice mild fatigue when chewing tougher foods during the first few weeks. This is expected and usually improves as you adapt.
Botox Recovery Timeline
Days 1-3 – Minor redness, tenderness, swelling, or bruising may be present. Most patients see little or no treatment effect at this stage.
Days 3-7 – The early effect begins to develop and muscle activity gradually reduces.
Days 10-14 – The full treatment effect is typically established and the final result can usually be assessed accurately.
Months 3-6 – The effects gradually wear off and muscle activity slowly returns.
Possible Side Effects of Botox
Most side effects are mild and temporary.
- Common – Mild discomfort at the injection sites, redness, swelling, bruising, and temporary headache.
- Uncommon – Temporary asymmetry, a feeling of heaviness, or chewing fatigue following masseter treatment.
- Rare – Unintended weakness of nearby muscles, eyelid drooping, eyebrow asymmetry, smile asymmetry, or prolonged weakness beyond the expected duration of treatment.
Most unwanted effects improve naturally as the toxin wears off.
When to Contact Your Clinician
Please seek advice if you experience:
- Increasing redness, swelling, or pain after 48 hours
- Significant facial asymmetry
- Severe chewing difficulty
- Difficulty swallowing
- Difficulty speaking
- Symptoms that are worsening rather than improving
- Any unexpected or concerning change in facial function
Follow-Up
A review appointment is often recommended approximately 2 weeks after treatment, as this is the earliest point at which the final effect can be accurately assessed.
Occasionally, minor adjustments or additional treatment may be advised.
