Botox Anti-Wrinkle Injections

Botox anti-wrinkle injections at Esthé Laser Clinic are administered by qualified medical practitioners using pharmaceutical-grade botulinum toxin type A to temporarily relax the facial muscles responsible for dynamic wrinkle formation. Dynamic wrinkles — expression lines that form when muscles contract during smiling, frowning, or squinting — respond directly to this approach: by reducing the force of the underlying muscle contraction, the skin above smooths out. Treatment areas include horizontal forehead lines, vertical frown lines between the brows (glabella), and crow's feet at the outer corners of the eyes. The effect develops over 3–7 days and lasts 4–6 months, after which the muscle activity gradually returns to its baseline. Regular maintenance injections 2–3 times per year sustain the smoothing effect.

Botulinum toxin type A (the active ingredient in Botox and its licensed equivalents) is a neurotoxic protein produced by Clostridium botulinum that, when injected in very small quantities into a specific muscle, competitively blocks the presynaptic release of acetylcholine at the neuromuscular junction. Acetylcholine is the neurotransmitter that signals the muscle fibre to contract; without it, the targeted fibres cannot generate the contraction force that would otherwise indent the overlying skin. The result is a temporary, controlled weakening of the injected muscle — not paralysis at clinical treatment doses, but a visible reduction in contractile force that translates to a smoother skin surface over the treated area. At Esthé Laser Clinic in Prague's Na Příkopě, botulinum toxin injections are administered exclusively by qualified medical practitioners, in line with the Czech regulatory requirement that schedules these treatments as prescription-only medical procedures. This is a meaningful distinction from beauty salon or non-medical aesthetic clinic settings: the physician can assess suitability, manage contraindications, and treat complications. The three most commonly treated areas are the horizontal forehead lines (frontalis muscle), the vertical glabellar lines between the eyebrows (procerus and corrugator supercilii muscles), and the crow's feet at the outer canthi (orbicularis oculi muscle). Each area is treated with precisely calibrated doses at multiple injection points distributed across the target muscle. The frontalis injections are placed to relax the horizontal forehead lines while preserving the eyebrow elevation that prevents brow ptosis — one of the most common adverse effects of poorly placed forehead Botox. The glabella injections address the angry or concentrated expression created by the frown muscles, with doses adjusted to the patient's muscle bulk and expression depth. Crow's feet injections smooth the radiating lines at the outer eye corners that develop during squinting and smiling. The onset of effect takes 3–7 days; the full effect is visible at 14 days and is typically assessed at a 2-week review. Duration is 4–6 months, after which the neuromuscular junction gradually regenerates its ability to release acetylcholine and muscle activity returns to baseline. Most patients maintain the result with 2–3 treatment sessions per year, and there is evidence that regular treatment over 2–3 years leads to progressive reduction in the muscle's baseline contractile force, allowing some patients to extend the interval between sessions. Non-cosmetic indications that may be assessed during consultation include hyperhidrosis (excessive sweating, particularly of the axillae — the toxin blocks the cholinergic sweat gland innervation) and chronic migraine prophylaxis, which are clinical applications with strong evidence bases. Preparation: stop aspirin, ibuprofen, and anti-platelet medications 10 days before (bruising risk). Avoid alcohol 24 hours prior. Do not schedule Botox within 2 weeks of dental treatment (infection risk). Arrive with clean, makeup-free skin. Aftercare: do not massage, press on, or lie face-down for 4 hours after the injections. Avoid strenuous exercise, saunas, and alcohol for 24 hours. Avoid significant sun or heat exposure for 48 hours. Contraindications (absolute): pregnancy and breastfeeding, known allergy to botulinum toxin or its excipients (human albumin), active systemic neuromuscular disease (myasthenia gravis, Lambert-Eaton syndrome, amyotrophic lateral sclerosis), active infection at the injection sites. Relative contraindications: aminoglycoside antibiotic use (enhances toxin potency), blood clotting disorders.
