Kiss those wrinkles goodbye with Botox. A highly purified form of botulinum toxin A, Botox is injected in very small amounts into specific muscles and acts by blocking the transmission of nerve impulses to muscles to paralyze them. Many states stipulate that only medical doctors may administer Botox; some states allow registered nurses or physician’s assistants to deliver Botox with doctor supervision. In addition to using Botox for wrinkles, Botox has been proven to help with migraines and excessive sweating. Medical spas are generally a hybrid of a medical office and a day spa operated under a physician’s license and care. With treatments and products that are stronger, medical-grade or physician-strength, a medical spa is more about dramatic visible results and less about relaxing and pampering treatments, though many make an effort to combine the two, offering medical treatments in a spa-like environment. Be sure to ask questions of spa management before booking.
