Botulinum toxin injections
Botulinum toxin injections reduce the movement of a target muscle temporarily by delivering a measured dose into it; the unit of measure is the unit.

This is the administration of a prescription medicine. The substance is botulinum toxin, the person administering it has to be a doctor, and the treatment begins with an examination. That is what separates it from a cosmetic treatment, and it is why you will see it called botulinum toxin rather than a brand name throughout this site — naming a prescription-only medicine in advertising is restricted in Türkiye and in the UK alike.
The unit of measure is the unit. Every area has its own dose range, and that range narrows or widens with how strong your muscles are. Nobody gets a standard dose for an area: a patient with strong, mobile expression muscles and a patient with weak ones need different amounts.
The effect is not permanent. It begins 3–7 days after treatment, settles fully at 10–14 days and lasts 4–6 months. That impermanence is not a shortcoming — it is what makes the dose adjustable each time.
No injectable treatment other than botulinum toxin is performed at this clinic. Dermal fillers, mesotherapy and similar procedures are outside our scope, and we will say so rather than refer you on the day.

Decision guides
- How many units?The dose is calculated in units and varies by area: 8–20 for the forehead, 10–25 for the frown lines (glabella), 6–12 per side for crow’s feet, 20–30 per side for the masseter, 4–8 for a gummy smile and 50 per side for underarm sweating. The exact dose is set by assessing the strength of the target muscle at examination.
- The first 14 daysFor the first 4 hours after treatment you do not lie down and do not massage the area; the effect starts on days 3–7, settles fully at days 10–14, and the dose is assessed at the day-14 review. In the expression areas the effect lasts 4–6 months.
Frequently asked questions
How many units will I need?
It depends on the area. Typical ranges are 8–20 units for the forehead, 10–25 for the frown lines (glabella), 6–12 per side for crow’s feet, 20–30 per side for the masseter, 4–8 for a gummy smile and 50 per side for underarm sweating. The exact dose is set after your muscle strength is assessed at examination.
How long does the effect last?
Usually 4–6 months in the expression areas and 6–9 months for masseter and sweating treatment. The first treatment often lasts slightly less; with regular repetition the interval can lengthen because the muscle weakens.
Will my face look frozen?
Not when the dose is calculated correctly. A frozen look is what happens when the target muscle receives more units than it needs, or when neighbouring muscles are affected unnecessarily. The aim is to reduce movement, not to end it.
What should I avoid afterwards?
Do not lie down or massage the area for the first four hours. Avoid exercise, saunas, steam rooms and alcohol for the first day. If you take blood thinners the chance of bruising is higher and you need to tell us before treatment, not after.
Can I fly home the same day?
Yes. There is no restriction on flying after botulinum toxin treatment, but stay upright for the first four hours, which usually means the flight itself is fine and the nap is not. The day-14 review is done by photograph and message once you are home.
