What is botulinum toxin?
Botulinum toxin type A is a purified neurotoxin produced by the bacterium Clostridium botulinum. In aesthetic medicine, it is used in extremely small, precisely measured doses to temporarily block the nerve signals that cause specific facial muscles to contract. Without the muscle contracting, the overlying skin relaxes and dynamic wrinkles — those formed by repeated muscle movement — smooth out.
The treatment does not numb the face or create an expressionless result when administered correctly. A skilled practitioner like Dr Bangalee treats only the targeted muscles while leaving surrounding muscles fully functional, preserving natural facial movement and expression.
What botulinum toxin treats
The most common treatment areas are the glabella (frown lines between the brows), forehead lines, and crow's feet at the corners of the eyes. These are all areas where repeated muscle contractions over years create permanent creases in the overlying skin. Other areas include bunny lines on the nose, lip lines, dimpled chin (mentalis), neck bands (platysma), and brow lifting.
Botulinum toxin treats dynamic wrinkles — those that appear or deepen during facial expression. It is less effective on static wrinkles (present even at rest without muscle contraction), which are better treated with dermal fillers, chemical peels, or resurfacing treatments. Often a combination of both botulinum toxin and fillers achieves the most comprehensive result.
What to expect — treatment and results
Treatment takes 15–30 minutes. A series of small injections are placed with a fine needle into the target muscles. Discomfort is minimal — most patients describe a brief pinching sensation. Most people return to their usual activities promptly, though this varies. Avoid rubbing the treated area for 4 hours and strenuous exercise for 24 hours post-treatment.
Results begin to appear within 3–5 days and reach full effect at 10–14 days. Duration varies by individual, treatment area, and units administered — typically 3–4 months. With consistent treatment, many patients find the results last progressively longer as the target muscles weaken slightly over time.
