Anti-Wrinkle Injections (Botulinum Toxin)

Botulinum toxin works by blocking acetylcholine release at the neuromuscular junction, temporarily preventing the small facial muscles that create expression lines from contracting fully. The result is a softening of dynamic wrinkles — lines that appear with facial movement — while at-rest skin texture and static wrinkles are minimally affected. At Klinika preventivní dermatologie the injections are performed by a dermatovenereologist, whose anatomical…

The consultation that precedes the injection session is as important as the procedure itself. The physician observes your facial movement to map which muscles are driving which lines, assesses the depth of the lines at rest versus during expression, and plans the injection map and dosing accordingly. The goal is not immobility but calibrated softening: enough relaxation to smooth the expression lines without obliterating natural movement or producing an…

Injections are placed with very fine needles; a topical anaesthetic is not usually needed for the brief, superficial passes used in botulinum-toxin treatment, though EMLA can be applied on request for sensitive patients. The procedure takes around fifteen to twenty minutes. Minor puncture marks and occasional small bruises may appear at injection sites and resolve within a day or two; ice applied briefly after each injection minimises this. The effect…
