Frequently Asked Questions

How can wrinkle relaxers help with Bruxism (teeth grinding)?

Sometimes masseteric hypertrophy is caused by Bruxism, which is the involuntary or habitual grinding of the teeth, typically during the night. This will cause the masseters to enlarge and if left untreated will cause TMJ dysfunction and orofacial pain. Wrinkle relaxer is injected directly into the masseter muscle. The muscle is weakened enough to stop involuntary grinding of the teeth and clenching of the jaw. This significantly relaxes the muscle and reduces the wear and tear on the teeth due to grinding. Voluntary movements, such as chewing and facial expressions, should not be affected at all. The procedure takes approximately 5 minutes and there is no down time following treatment.

How many units will I need?

The recommended dose will vary depending on individual muscle strength but approximately from 50 units per side.

When will I see results?

Following your treatment, results may become visible within 2-5 days, with full results taking up to 10-14 days to become apparent. The recommended dose will vary depending on individual muscle strength.

How long do the effects of wrinkle relaxers last?

The effects usually last between 3 to 5 months and gradually decrease over time. Regular treatments may improve the longevity of treatment effects.

What should I avoid after treatment?

+ Exercise or excessive sweating (saunas, steam rooms, etc) for 24-48 hours.

+ Wearing make-up for 24hours.

+ Direct UV exposure.

+ Lying down or sleeping for 4hours post-treatment.

+ Refrain from rubbing or massaging the treated area for 48 hours.

+ Tight or firm prolonged pressure of the treated area (for example avoid wearing a helmet that fits tightly on the treatment area).
