【阅读理解】Beauty with Botox Botox injections are one of the most popular cosmetic treatments in the world. Celebrities like Madonna, Kylie Minogue and Liz Hurley are rumoured to be keeping the wrinkles at bay this way. Sir Cliff Richard admitted to having had the treatment and now it is an increasingly popular choice for ordinary women looking for a quick way to look younger. What is Botox? Botox is made from “botulinum toxin”, a poison produced by the bacterium clostridium botulinum. This bacterium causes botulism—a severe form of food poisoning. In small quantities, however, Botox merely interrupts nerve muscles in the face. Botox first began to be used in 1980 to treat many muscle disorders such as lazy eye, eye ticks and uncontrolled blinking. Cosmetic treatments were pioneered by dermatological surgeons in 1987. In small doses, Botox works by paralyzing the muscles of the face which are used in frowning and raising the eyebrows. When these muscles relax, the fine lines and wrinkles smooth out. Unfortunately, when it is overdone, Botox treatment can leave the face with a lack of expression. This is reputed to have caused a problem for some actors. Armpit attack Botox is reportedly a favorite with Oscar nominees who don’t want to work up a sweat on the red carpet. Some stars have injections in their armpits to paralyze the sweat glands there. This way they can receive their awards knowing they don’t have sweaty patches under their arms and hand back their couture outfits unstained. How long does it last? Injections take effect about three to seven days after treatment and the effect lasts three or four months. A treatment costs roughly £200. With repeated treatments, atrophy or thinning of the muscles occurs, which produces longer lasting results. Botox may be unsuitable for use around the mouth as the muscles there are important for facial expressions and eating. Side effects Soreness or mild bruising can occur around the injection site. In rare instances patients may experience a droopy eyebrow or eyelid. Headaches can also occur. Since it is still a relatively new treatment, any possible side effects of long-term use are still unknown. Botox should only be administered by experienced and well- trained doctors or nurses. A high dose could cause poisoning, or an exaggerated effect. Botox and Bollinger Botox parties are causing concern amongst practitioners. People are receiving treatments whilst sipping champagne. The American Academy of Dermatology has warned against this practice. Alcohol and Botox do not mix well. Not only can booze intensify bruising but it can also wash the toxin away from the target muscle.
