Botox injections are intended to temporarily reduce the appearance of wrinkles by preventing the muscles from contracting so the skin does not crease in the normal way. It is a quick and painless treatment that has been very successful in treating the signs of aging. One Botox treatment does not last forever as it is only a temporary measure that will need regular repeating. It uses Botulinum Toxin Type A to block the nerves from sending messages to the muscles in order for them to contract. Although Botox treatment will need to be repeated to continue enjoying the benefits, the continued use of Botox weakens the muscles helping the effects of Botox to last longer
Botox, when injected into muscle tissue, affects the nerves that are connected to the muscle by obstructing the neural pathway into the muscle. This means than when the nerves are supposed to transmit the signal to activate the muscle fibres, they cannot. Consequently, the muscles will not contract when the nerves have been injected with Botox so when a smile occurs, the muscles that would normally operate, around the eyes for example, would remain relaxed and the usual deep wrinkling will not occur. Botox does not last for ever and is a temporary treatment.
The procedure used in Botox treatment is safe so long as the performing surgeon is experienced in carrying out such procedures. It is an art best left to the professionals and the risks associated with Botox is often more to do with the surgeon than the Botox. How long does Botox last will be around 4 months on average, after which further treatments will be necessary.
There are some side effects that can be experienced but they are relatively minor and rarely last for long. The symptoms that can be experienced include feeling sick, the temporary drooping of the eyelids, flu-like symptoms, experiencing headaches, redness at the injection sight, twitching eyes and facial pain.
Most people are suitable for Botox injections, which are non-surgical non-invasive treatments. Botox lasts for about 4 months. However, those people who are pregnant or planning pregnancy and women who are breastfeeding are not suitable for the Botox procedure. Also, there are certain antibiotics and quinidine that can react badly to Botox. There is also a small chance with any injection procedure that an infection can occur.
Those people suffering from neurological disorders should inform the surgeon and may render the treatment unsuitable.
