Botox injections are the best known of a group of medications that use various forms of botulinum toxin to temporarily paralyze muscle activity. This toxin is produced by the microbe that causes botulism, a type of food poisoning. Botox injections are noted primarily for the ability to reduce the appearance of some facial wrinkles. They are also used to treat such problems as repetitive neck spasms (cervical dystonia), excessive sweating (hyperhidrosis), overactive bladder and lazy eye. Botox injections may also help prevent chronic migraines in some people. Botox was the first drug to use botulinum toxin. Other products now include Dysport, Myobloc and Xeomin. Each is a little different, particularly when it comes to dosage units, so they aren’t interchangeable
Why it’s done
As you get older, the appearance and shape of your face is altered because of normal age-related changes. Your skin becomes less elastic and looser, and fat deposits decrease in some areas of your face and increase in others. Age-related changes in your face that may be reduced with a face-lift include the following:
- Sagging appearance of your cheeks
- Excess skin at your lower jawline (jowls)
- Deepening of the fold of skin from the side of your nose to the corner of your mouth
- Sagging skin and excess fat in the neck (if the procedure includes a neck lift)
A face-lift isn’t a treatment for superficial wrinkles, sun damage, creases around the nose and upper lip, or irregularities in skin color.
