Botulinum toxin type A is a purified protein injected in very small doses to relax specific facial muscles. It softens dynamic wrinkles — lines that appear when you frown, raise your brows or smile — and prevents them from deepening. Effects appear in 3–7 days and typically last 3–4 months.

How the appointment runs
- 1
Muscle mapping
You are asked to frown, smile and raise your brows so the pattern of each muscle can be marked.

Dosing
Units are chosen per point. First sessions stay conservative to keep expression natural.
- 3
Injection
A very fine needle places small amounts at each point. Most patients describe it as brief pinches.

Two-week review
Symmetry and movement are checked. Small top-ups are made if needed.
Aftercare

- Skip strenuous exercise, sauna and alcohol for 24 hours
- Make-up can be applied the next morning
Risks and side effects
Temporary redness, small bruises and mild headache are common. Less often, an eyelid or brow can droop for a few weeks if the product spreads; careful placement and dosing reduce this risk. Treatment is not given during pregnancy or breastfeeding, or with certain neuromuscular conditions.
Questions about this treatment
Will I lose my facial expressions?
Not with correct dosing. The aim is softer movement, not a frozen forehead. A conservative first session shows how your muscles respond.
What happens if I stop?
The muscles gradually return to their previous activity. Wrinkles do not become worse than before treatment.
Is it the same as filler?
No. Botulinum toxin relaxes muscles; fillers restore volume or structure. They are often combined but do different jobs.
