European Wrinkle Smoother
The treatment, an injectable gel called Restylane, has long been
used in Europe and is the third injectable wrinkle treatment to win FDA
approval, the Associated Press reports.
The other two are Botox and Collagen. Botox temporarily paralyzes
muscles beneath the skin to smooth frown lines between the eyes.
Collagen is used to fill other wrinkles, including those Restylane can
treat. Both wrinkle fillers last about six months.
Restylane is made with hyaluronic acid, a substance normally found in the skin that helps keep it plump.
In studies, 138 patients had wrinkles on one side of the nose
injected with Restylane and the other side with collagen. Both sides
appeared comparable. Most of the patients studied were Caucasian.
Restylane manufacturer Q-Med AB of Sweden has agreed to do more
research on whether the treatment will cause any pigment alternations
if used by non-Caucasians, although FDA said widespread use in other
countries hasn't raised concern.
