How long does BTX last?
Duration varies with the product, the dose and individual metabolism. The timing of any repeat is planned at review rather than to a fixed schedule.

Only with excessive doses. The aim is to relax the target muscle while preserving natural expression; a frozen look is a sign of overdosing, not of the treatment itself.
Read the full page →Is BTX safe long-term?
Botulinum toxin has been used clinically for more than 30 years. Appropriate long-term use has not been shown to cause lasting structural change, and the dose is reviewed at each visit.

Forehead lines are horizontal, made by the brow-raising frontalis; frown lines are the vertical 11s between the brows, made by the glabellar complex. They are assessed and dosed separately, because the same muscles position the brows.
Read the full page →What treats lines that are already etched in?
Dermal remodelling: fractional lasers, radiofrequency microneedling and collagen-biostimulating treatment rebuild the creased skin over a planned series, usually with muscle relaxation alongside. Deeply etched single lines occasionally take a small amount of filler.
Read the full page →What is jaw BTX?
Injection of botulinum toxin into the masseter at the angle of the jaw. The muscle contracts less and shrinks through disuse over the following weeks. It addresses muscle bulk only, not fat, skin laxity or bone.
Read the full page →Does masseter BTX help teeth grinding?
It reduces the force the masseter can generate, lowering the load on the teeth and jaw joint. It does not remove the cause of bruxism or replace a dentist's night guard, so dental review is part of the plan.
Read the full page →Can masseter BTX make my cheeks look sunken?
It can, in a thin face or with over-treatment, because the masseter supports the skin at the jaw angle. The whole lower face is examined before the dose is set, and the treatment is sometimes declined.
Read the full page →How does BTX treat a gummy smile?
Micro-doses are placed in the specific lip-elevator muscles that overpull, reducing the excess lift. The smile still rises naturally; the extra gum display is reduced.
Read the full page →Is botulinum toxin a prescription medicine in Singapore?
Yes. Type A toxin is prescription-only, products are registered with the Health Sciences Authority, and a registered medical practitioner injects it after a documented consultation. Units are product-specific and not interchangeable.
Read the full page →Why is forehead BTX dosed more cautiously than frown lines?
Because the frontalis is the only muscle that lifts the brows. Over-treating it drops the brow and creates a heavy, tired look, whereas the frown muscles pull the brows down and in. Forehead dosing therefore preserves some frontalis tone while softening the lines.
Read the full page →Can BTX make my eyelids feel heavy?
Yes, when the forehead was working to hold heavy or hooded lids open. Relax that frontalis fully and the brows settle and the hooding lands. Brow position and lid reserve are read first, and where the forehead is compensating, dosing is conservative or the plan is redirected to the lid.
Read the full page →Can BTX fix droopy or hooded eyelids?
No. BTX relaxes muscle, and a lid that droops because of its muscle or heavy skin is referred for oculoplastic or plastic surgery specialist assessment. Relaxing the forehead can make hooding more noticeable, which is why brow position is examined before any forehead treatment.
Read the full page →How soon does BTX start to work?
Not immediately. The treated muscle begins to contract less first, and any visible change follows: for a bulky masseter, slimming develops gradually over the following weeks as the muscle loses bulk. The response is reviewed once it has settled, which is also when early asymmetry is addressed.
Read the full page →Why is a review visit part of BTX treatment?
Because dosing starts conservatively and is planned from the muscle in front of the doctor, the response is checked at a follow-up timed individually. That is when early asymmetry can be corrected before any further dose is recommended, and when the timing of any repeat is decided.
Read the full page →What happens if BTX spreads to a neighbouring muscle?
It can cause a heavy brow or eyelid, an altered smile or tiredness when chewing, depending on the area. These effects are temporary, but they last as long as the toxin does and cannot be reversed on demand. A bothersome droop should be reported to the clinic the same day.
Read the full page →Can jaw BTX cause a lopsided smile?
Less commonly, yes. The muscles that lift the corner of the mouth lie just in front of the masseter's border, and toxin placed or spreading into them makes the smile uneven on that side. The masseter is mapped with the jaw clenched so those smile muscles are kept clear.
Read the full page →What is paradoxical bulging after masseter BTX?
A bulge at the jaw angle on clenching when part of the masseter was not treated. If the deep fibres are weakened but the superficial layer is not, the untreated fibres bunch and the angle looks bigger. It is a reason for review and is addressed by treating the layer that was missed.
Read the full page →How do I know if my wide jaw is muscle or bone?
Clench your back teeth and feel the angle of the jaw, just in front of and below the ear. Muscle bulges and firms under the fingers and softens on relaxing. Bone feels hard whether clenched or relaxed, and soft tissue that can be pinched points to fat or skin. Only muscle responds to BTX.
Read the full page →Will my jaw muscle grow back after BTX?
The block is reversible: the nerve rebuilds its signal, function returns, and the masseter can rebuild if the clenching or grinding habit continues. That is why the plan is individual and reviewed over time, and why dental review sits alongside treatment when bruxism is the reason.
Read the full page →Can BTX be used for excessive sweating?
Yes. The same molecule blocks the nerve-to-gland signal when injected into the skin over the sweat glands rather than into a muscle, and it carries strong evidence for underarm sweating. It sits on a treatment ladder after clinical-strength antiperspirants and iontophoresis.
Read the full page →Is BTX the first treatment for sweaty underarms?
No. Clinical-strength aluminium chloride antiperspirants applied at night are the first step, and iontophoresis has good data for palms and soles. BTX is the next rung. Sweating that is generalised, new in adulthood or occurs at night is investigated for an underlying cause first.

Injected into the platysma, it relaxes the vertical neck cords and softens horizontal neck lines, sometimes called the Nefertiti lift. Injected into the depressor anguli oris, it reduces the downward pull at the corners of the mouth that reads as a stern or sad expression.
Read the full page →Are Botox and Dysport the same thing?
No. Botox is a brand name for one botulinum toxin product, and several formulations are registered in Singapore. They differ in diffusion profile, onset and unit potency, and each is measured in its own units, so a dose quoted for one brand cannot be converted into another.
Read the full page →What should I tell the doctor before having BTX?
Any neuromuscular condition such as myasthenia gravis, medicines such as some antibiotics or muscle relaxants, blood-thinning medicines and supplements such as fish oil, pregnancy, breastfeeding or plans for pregnancy, and any previous BTX product and how you responded. Bring photographs of your expressions from earlier years.
Read the full page →Can I have BTX while breastfeeding?
It is generally avoided in pregnancy and breastfeeding because its safety in these groups has not been established and nothing about it is urgent. Treatment is deferred until the doctor judges it acceptable. A consultation can still be useful for planning the order of treatment afterwards.
Read the full page →Why does BTX sometimes seem to stop working?
Often the line has become static. BTX reduces movement, so a crease now visible at rest will not disappear however the muscle is dosed, and needs skin-directed treatment. A muscle can also rebuild if a clenching habit continues. Dose, placement and product are reviewed before more is given.
Read the full page →What should I avoid after BTX?
For the first day, avoid rubbing or massaging the treated areas, strenuous exercise, heat such as saunas and alcohol, and stay upright for a few hours if advised. For the first week, avoid facials, massage and pressure over the area unless the doctor agrees. Small bumps and bruises settle on their own.
Read the full page →Is BTX worth starting in my twenties to prevent wrinkles?
It is considered preventive once dynamic lines are visible in movement, which for expressive faces is often the late twenties. Before any line appears there is nothing for it to soften. Whether it is worthwhile depends on your expression pattern and brow position, assessed individually.
Read the full page →Can BTX treat lines under the eyes?
Only the dynamic kind. Under-eye lines come in three types: lines made by the orbicularis muscle, which respond to precisely dosed BTX; static lines etched into the collagen; and crepey texture from thin skin, which need skin-directed treatment. Dosing near the eye is kept conservative.
