Botox — Muscle-Relaxing Expression Line Treatment

Botulinum toxin (Botox) injections at Kožní Keclíková use Allergan Botox — supplied through Neomed s.r.o. — to temporarily relax the muscles that cause expression lines in the upper face. The treatment is performed exclusively by physicians and is indicated primarily for the three classic areas: horizontal forehead lines, glabella (frown lines between the brows), and crow's feet around the lateral eye area. The clinic's approach favours precision over volume: the physician assesses the patient's natural facial movement first, determining the minimum effective dose for a natural rather than frozen appearance. Effect onset is within a few days, full result settles in about two weeks, and the relaxation effect lasts approximately three to four months.

Botulinum toxin type A (brand name Botox, manufactured by Allergan) works by blocking the release of acetylcholine at the neuromuscular junction. When a small, targeted dose is placed into the belly of a facial muscle, that muscle cannot contract with full force for the duration of the toxin's effect — typically three to four months at Kožní Keclíková's standard dosing. The overlying skin, deprived of the repeated folding force of the muscle beneath it, gradually smooths; existing lines soften and the pattern of new line formation is interrupted during the treatment period. At the Medincentrum clinic, Botox is supplied by Allergan via Neomed s.r.o. and is indicated specifically for expression lines in the upper face, where muscle-driven wrinkling is the primary mechanism. The three principal treatment zones are the frontalis (horizontal forehead lines), the procerus and corrugator complex (vertical glabella frown lines between the brows), and the orbicularis oculi (crow's feet at the outer eye corners). The physician is explicit that lower-face concerns — nasolabial folds, lip lines, chin dimpling, and marionette lines — respond better to fillers than to toxin and will typically redirect those enquiries accordingly, which reflects a treatment philosophy of matching modality to mechanism rather than applying one product universally. The injection session begins with the physician having the patient animate through the full range of upper-face expressions — raising the brows, frowning, squinting — to map the precise muscle insertions and the vectors of movement. Injection points are then marked at the optimal locations to weaken each muscle without affecting adjacent ones. Each point receives a micro-injection of a few units of reconstituted Botox using a very fine needle; topical anaesthetic is not routinely required. The entire session takes fifteen to twenty minutes. Onset of effect begins 48 to 72 hours post-injection and reaches its plateau at approximately two weeks. The physician may ask the patient to return at the two-week mark for a review and, if needed, a small touch-up dose. Duration of effect varies between three and four months in most adults, with the lower end seen in patients with large, active muscles (common in younger males with prominent frontalis). Regular patients often find that with repeated treatments over years, the duration extends slightly as the target muscles partially atrophy. Botox is not recommended during pregnancy or breastfeeding, at sites of active skin infection, or for patients with certain neuromuscular conditions. The physician reviews each patient's suitability at the consultation.
