Botox and Dysport are two of the most popular brands of botulinum toxin in cosmetic treatments. This powerful toxin acts as a muscle relaxant and is effective at smoothing wrinkles and facial expression lines that develop over time, especially when making facial expressions. When we laugh or show surprise, the facial muscles contract, moving the skin and forming creases that, over time, become more noticeable.
The action of Botox and Dysport works by inhibiting the release of acetylcholine at the neuromuscular junction, blocking muscle contraction. In other words, these toxins prevent the facial muscles from contracting, thus avoiding the formation of new wrinkles or the deepening of existing ones.
The most common areas for these toxins to be applied are the wrinkles on the forehead, specifically the lines formed by the contraction of the frontalis muscle. Botox treatment in this area eliminates horizontal expression lines, commonly known as “code of bars.” It is also highly effective for treating periorbital wrinkles, or “crow’s feet,” which are caused by the repeated action of the orbicularis oculi muscle. Additionally, the frown lines, which are often very noticeable, respond very well to botulinum toxin, making it one of the most requested areas by patients due to the difficulty of other treatments in addressing them effectively.
After application, Botox and Dysport smooth out expression lines by preventing the facial muscles from contracting. Results start to become visible in as little as three days, when the toxin begins blocking muscle contraction, with improvements noticeable after two days.
Thanks to Botox or Dysport treatment, expression lines disappear or significantly fade, depending on the depth of the wrinkles. Best of all, despite the visible results, patients retain their ability to express themselves naturally, without losing the freedom to show emotions. The face takes on a refreshed, youthful, and natural appearance.
