Botulinum Toxin — Expression Wrinkle Treatment

Physician-administered botulinum toxin injections to relax the facial muscles responsible for forehead lines, frown lines between the brows and crow's feet around the eyes. MUDr. Vladimíra Brychtová's neurological background — giving her exact anatomical knowledge of facial muscles and nerve pathways — makes her placement of botulinum toxin particularly precise, reducing the risk of unwanted muscle diffusion or brow ptosis. The clinic uses established brands including Botox, Vistabel and Dysport. The same treatment is available for hyperhidrosis (excessive sweating). Results develop over five to fourteen days and typically last three to five months.

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 three to five months, at which point the treatment can be repeated. 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 look of the face is preserved rather than frozen. 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 complications such as eyebrow drop or asymmetric smile at other clinics often seek practitioners with deeper anatomical grounding. For hyperhidrosis — excessive sweating of the underarms, palms or forehead — botulinum toxin is injected intradermally at multiple points across the sweating zone, blocking the acetylcholine signal to the eccrine sweat glands rather than to a muscle. The effect is highly reliable, typically reducing sweating by 80 to 90 per cent within two weeks and lasting six to twelve months before the treatment needs repeating. Before each session MUDr. Brychtová reviews contraindications including pregnancy, breastfeeding, neuromuscular junction disorders (myasthenia gravis, Eaton-Lambert syndrome) and any medications that interfere with neuromuscular transmission. The injection session itself takes fifteen to twenty minutes; no anaesthetic is needed for most patients. Patients are advised to stay upright, avoid rubbing the treated area and refrain from strenuous exercise for the four hours following the session.
