Wrinkle relaxers (neuromodulators)
Tiny injections of botulinum toxin type A that temporarily soften the muscle movements that fold the skin into lines: frown lines, forehead lines, crow's feet. Also used to slim a strong jaw muscle, lift a downturned mouth corner, and switch off underarm sweating.

How it works
The toxin blocks the signal between nerve and muscle at the injection point, so that muscle contracts less. The skin above stops creasing and existing lines soften over one to two weeks. The effect fades as new nerve endings grow, so it is repeated.
Four illustrative steps. Select a step to highlight it; the optional anatomy view explains the same mechanism.
A schematic setting on one anatomy—not a prediction of your result.
Recovery, in practical terms
Small bumps for 15 to 30 minutes. Avoid rubbing the area or lying flat for a few hours.
What it can feel like: Mild. Quick pinches.
What people discuss
Lines that appear when you make an expression, a wide lower face from jaw clenching, sweaty underarms.
Reasons to pause
Pregnant or breastfeeding, some neuromuscular conditions, an active infection at the site.
This list is not exhaustive. A clinician must assess your health, medications, skin and goals.
Risks worth understanding
- Bruising
- A temporary heavy brow or drooping eyelid if product spreads
- Asymmetry, usually correctable at follow-up
- Botulinum toxin products carry warnings about effects spreading beyond the injection site; swallowing or breathing difficulties need urgent medical attention
Ask your clinician
- Which product and how many units, and why that number?
- How do you avoid a heavy brow or eyelid droop?
- When is my follow-up?
Sources, approval context & editorial limits
FDA-approved botulinum toxin products carry a boxed warning. Approval is product- and indication-specific; many cosmetic uses are off-label.
Sources support regulatory and safety context; not every efficacy claim or range has been independently verified.
Educational information, not medical advice or a personal recommendation. Independent clinical review is pending. A qualified clinician must assess individual suitability. Timings, relative costs and visuals are illustrative, not guarantees.
