Botox is a drug that come from a bactieral toxin called Botulin, and it it can be used for medical purposes to treat certain muscular conditions, as well as cosmetically to treat wrinkles.
Botox takes effect by temporarily paralyzing the muscles in which the Botox is injected, which helps to reduce the appearance of wrinkles.
The Botox in itself does not produce any painful sensations. The only discomfort during the process may come from the needle injection, but the use of a topical anesthetic can greatly reduce any pain that you may experience.
Results can be seen after the first treatment, with the wrinkles beginning to disappear starting two to four days after the injection. The maximum level of the Botox's effect takes place about ten to fourteen days after the injection.
The Botox injections can hold their effects for three to twelve months, depending on what condition is being treated. Once the effects of the previous injection begin to wear off, it is safe to have another injection, and there is no medical limit for how many injections one can have throughout their life. But the body's immune system will gradually build up antibodies for the Botulin toxin with every injection, which can eventually render the treatment ineffective after a certain point.
The wrinkles that had been reduced from the previous Botox treatments will return to their previous appearance after the effects of the Botox injections wear off, but discontinuing the treatment will not make your wrinkles worse than they were originally.
The most common side effects of having botox done are pain, swelling, or bruising near the site of injection. In rarer cases, you may experience flu-like sensations, headaches, or and upset stomach. If the Botox is injected around the eye region, you may notice some bluured or double vision, but these effects are temporarily and will disappear on their own.
You should avoid using Botox if you are pregnant and/or breastfeeding, or have special skin conditions such as lupus erythematosis that can be aggravated by the injections.
