Botox vs filler
One relaxes muscle, the other adds volume. Lines made by movement belong to the first; hollows, folds and lost structure belong to the second. The commonest mistake in aesthetic medicine is treating one problem with the other's tool.
Botox vs filler: which suits whom?
Neuromodulators for dynamic lines, masseter bulk and some neck bands; hyaluronic acid filler for structural volume in small amounts; biostimulators when a slower, more diffuse volume effect is wanted. Both are prescription-only medical treatments in Singapore, decided at consultation.
| Neuromodulator ('Botox') | Dermal filler | |
|---|---|---|
| What it does | Relaxes targeted muscles | Adds or restores volume |
| Treats | Frown, forehead and crow's feet lines; masseter; neck bands | Cheeks, temples, chin, jawline, folds, lips |
| Onset | 3–14 days | Immediate |
| Duration | 3–4 months | 6–18 months by product and site |
| Reversible | Wears off | HA filler dissolvable |
| Main risk | Asymmetry, heaviness | Vascular occlusion, migration, overfilling |
| Our verdict | Established | Promising |
By the numbers
- systematic review
The world literature to 2018 recorded 146 new cases of filler-related vision loss, most after injection of the nose, glabella and forehead; HA was the commonest filler involved and few cases recovered vision.

Across 28 studies masseter thickness fell by roughly a quarter at three months regardless of the number of injection points, with high heterogeneity and bias.

Ten small studies (153 participants) reported improvements in sebum, pore size, erythema and texture but not hydration, and none reached the required sample size for a firm conclusion.

The reviews behind this comparison
- Preventive 'baby' neuromodulatorsWith the caveat that natural has a technical definition: movement preserved, proportions unchanged.Established
- 'Skin botox' and micro-toxA good adjunct in an oily-skin plan; a poor substitute for the laser work that actually changes texture.Promising
- Masseter slimming injectionsThe jaw is a muscle you use a thousand times a day; weaken it as much as the face needs and no more.Established
- Cheek and midface fillerMost faces that look 'done' were not filled badly on one day; they were filled reasonably on many days, and the filler stayed.Established
- Nasolabial fold fillerThe fold is where the face is falling, not where it is empty; fill the cause, then decide whether the line still needs anything.Established
- Filler dissolving and 'filler fatigue'Dissolving is not regret, it is a reset; what you do next, with energy rather than more gel, decides whether the fatigue comes back.Established
- Collagen stimulatorsThe decision deserves the slowest consultation in aesthetics.Caution
- Hyaluronic acid dermal fillersPlaced deep, in the right compartment, by someone who can dissolve it, HA filler is the most reversible structural tool in aesthetics. The problems come from the under-eye, from top-ups without reassessment, and from anyone who cannot name the artery they are avoiding.Established
