Two injectables, two different jobs
Botulinum toxin (often called Botox) temporarily relaxes the muscles that create expression lines, such as frown lines, forehead creases and crow's feet. Dermal fillers, usually made of hyaluronic acid, add volume or structure where it has been lost or where more definition is wanted.
Because they work in different ways, the right choice depends on what is causing the line or hollow you want to treat.
A simple way to think about your concern
A doctor will examine your face at rest and in movement, but these patterns are a helpful starting point:
- Lines that appear or deepen when you frown, raise your brows or smile often relate to muscle movement
- Lines or folds that are visible even when your face is relaxed may relate to volume loss or skin changes
- Hollows under the eyes, flat cheeks or thin lips are usually volume concerns
- Many people have a mix of both, so treatments are sometimes combined
What to expect from each
Botulinum toxin takes effect gradually over the first couple of weeks and wears off over time, so maintenance treatments are planned. Fillers show a change straight away, may swell slightly at first, and are gradually broken down by the body.
Both are medical treatments. They should be given by a qualified practitioner after a consultation that covers your medical history, expectations and possible side effects.
Questions to ask at your consultation
- Is my concern caused by movement, volume loss or both?
- What product will be used, and how long is it expected to last for me?
- What side effects should I watch for, and who do I contact if they happen?
- How will you keep my result looking natural?
