Botulinum Toxin — Expression Wrinkle Treatment

Botulinum toxin works by blocking the release of acetylcholine at the neuromuscular junction — the point where a motor nerve signals a muscle fibre to contract. A precisely measured dose injected into a specific facial muscle prevents that muscle from contracting with full force, allowing the overlying skin to smooth rather than crease with each expression. The treated muscle is not permanently affected; acetylcholine transmission slowly recovers over…

The wrinkle-relaxing applications at this practice include the frontalis muscle for horizontal forehead lines, the corrugator supercilii and procerus for vertical frown lines between the brows (glabellar lines), and the orbicularis oculi for crow's feet fanning outward from the outer corners of the eyes. Each injection point is planned based on how the patient's muscles move during expression — a dynamic assessment that guides placement so the natural…

MUDr. Brychtová's clinical training in neurology adds a specific layer of precision to botulinum toxin work. Neurologists map facial and trigeminal nerve anatomy in fine detail as part of their specialism; this knowledge is directly applicable to understanding where a toxin dose will and will not diffuse, and at what depth different muscle bellies can be reached with minimal overlap onto neighbouring structures. Patients who have previously experienced…
