Botox in İstanbul: dosing, safety and how to avoid a frozen look
Medical team, Nuance Clinic
Botulinum toxin is the most-performed aesthetic treatment in the world and the most commonly over-dosed. This guide explains how a doctor assesses muscle strength, why units are not a price list, what happens between day 3 and day 14, and how to judge a clinic's safety standards before you sit in the chair.
Quick facts
- Dose should follow muscle strength, not a per-area price list.
- Full effect appears at day 10–14; a two-week review matters.
- Under-treating first and adding later is safer than over-treating.
- Toxin does not replace filler, skin boosters or resurfacing.
What it is
- Botulinum toxin type A temporarily blocks the nerve signal to selected muscles. Lines caused by repeated movement soften, and lines that have not yet formed are prevented.
- It does not fill volume, tighten loose skin or treat sun damage — those need filler, energy devices or skin treatments.
Who it suits
- Forehead lines, glabellar (frown) lines, crow's feet, bunny lines, gummy smile, chin dimpling and neck bands
- Patients seeking prevention in their late twenties and thirties
- Not suitable in pregnancy, breastfeeding, neuromuscular disease (e.g. myasthenia gravis) or known allergy
Products we use
- Original, licensed botulinum toxin brands including Botox (Allergan), Dysport and Xeomin
- Product is reconstituted fresh, in front of you where you wish, and never diluted beyond protocol
How the treatment is performed
- Dynamic assessment: we watch you frown, raise, smile and squint before deciding on injection points.
- Skin cleaned; injections with a very fine needle, typically 4–8 points per area.
- The whole session takes minutes; you can return to work immediately.
Safety
- Correct dosing and depth prevent eyelid or brow drop; this is anatomy, not luck.
- We deliberately under-treat first-time patients and add at review, because toxin cannot be removed once injected.
- Full medical history is taken — certain antibiotics and neuromuscular conditions matter.
Before your appointment
- Avoid alcohol for 24 hours.
- Tell us if you are on aminoglycoside antibiotics or have any neuromuscular disorder.
- Do not book within two weeks of a major event, so there is time to fine-tune.
Aftercare
- Stay upright for 4 hours; no lying face down.
- No rubbing or facial massage for 24 hours.
- No gym, sauna or hammam for 24 hours.
- Active facial expressions in the first hours may help uptake.
Results and longevity
- First changes at day 3, full effect at day 10–14.
- Effect lasts 3–5 months; regular treatment often extends the interval over time.
- Deep static lines etched into skin need filler, skin boosters or resurfacing in addition.
Possible side effects and risks
- Common: small bruises, brief headache, transient heaviness.
- Uncommon: brow or eyelid ptosis (temporary, weeks), asymmetry — usually correctable at review.
- Rare: allergic reaction, flu-like symptoms.
Follow-up
A two-week review is part of every toxin treatment, with adjustment where needed at no extra charge.
Questions about this treatment
Will I look frozen?
Not with individualised dosing. We aim to weaken the pull of specific muscles, not to eliminate movement — most patients keep full expression with softer lines.
Is Botox safe long term?
Botulinum toxin has decades of clinical use in medicine and aesthetics. Long-term regular use typically means needing less product over time.
How old should I be to start?
When dynamic lines start to stay visible at rest — for many people that is between 27 and 35. There is no fixed age.
Can I combine it with filler?
Yes, and it is usually the better plan: toxin handles movement, filler handles volume.
