Botox (botulinum toxin type A) is one of the most researched drugs in medical history — in use for over 40 years. In aesthetic medicine, it blocks neuromuscular transmission, causing temporary muscle relaxation. Below, we answer the most frequent questions we hear from patients at J'ADORE INSTYTUT.

How does Botox work?

Botulinum toxin blocks the release of acetylcholine at the neuromuscular junction — the muscle stops contracting for several months, and the skin above it can smooth out.

Aesthetic indications — where is Botox used?

Botulinum toxin can be used in many areas of the face and body. In aesthetic medicine, it is most commonly used for:

  • Forehead lines
  • Glabellar lines — the "one" or "three" between the brows
  • Crow's feet at the corners of the eyes
  • Brow lift — subtle arch elevation
  • Bunny lines — wrinkles on the nose
  • Gummy smile
  • Lip flip
  • Corners of the mouth (marionette lines)
  • Venus rings — horizontal neck wrinkles
  • Bruxism — masseter muscle tension
  • Excessive sweating — underarms, hands, feet

When are results visible and how long do they last?

Botox results do not appear immediately — they require time for the toxin to act on the neuromuscular junction.

  • 24–48 h — first signs of action
  • 7–14 days — full results visible
  • 3–4 months — optimal effect level
  • 4–6 months — gradual return of muscle activity
  • After approx. 6 months — another session is necessary for many people

Preparations — Botox, Azzalure, Bocouture

In Poland, three main botulinum toxin type A preparations are available. All are prescription drugs registered for use in aesthetic medicine:

  • Botox (onabotulinumtoxinA) — Allergan/AbbVie, market standard
  • Azzalure (abobotulinumtoxinA) — Galderma, slightly different unit conversion
  • Bocouture (incobotulinumtoxinA) — Merz, purified toxin without complexing proteins

Who performs Botox at J'ADORE?

Botox for bruxism

Bruxism is the involuntary clenching or grinding of teeth, often unconscious — especially during sleep. Injecting botulinum toxin into the masseter muscle can bring relaxation and reduce headaches, neck pain and tooth wear.

Botox for excessive sweating (hyperhidrosis)

Botulinum toxin blocks sweat glands — not by destroying them, but by cutting off nerve stimulation. The treatment can significantly limit excessive sweating of the underarms, hands, feet or forehead.

  • Underarms — the effect often lasts for many months
  • Hands and feet — a treatment requiring higher doses, the effect is slightly shorter
  • Face (forehead) — smaller area, lower doses
