Washington: Botox cosmetic injections reduce wrinkles even with less frequent doses after two years of starting treatment and also have a wrinkle preventing effect, research says.
"After two years of treatment at recommended intervals, patients can potentially cut the frequency, and thus, the cost of their Botox treatments by half," said Roger A. Dailey, professor of oculofacial plastic surgery in the Oregon Health & Science University (OHSU).
The Botox research effort also demonstrated that the injections have a wrinkle preventing effect.
Patients who begin receiving injections between their 30s and 50s are able to prevent wrinkles from forming and eliminate existing wrinkles, said Dailey, head of the Casey Aesthetic Facial Surgery Center.
Based on previous studies, doctors advised patients who wished to reduce wrinkles in the area between the eyebrows - that they needed to have Botox injections every three months to maintain the cosmetic wrinkle-smoothing benefits. Such frequent treatment, however, deterred some patients, Dailey said.
He studied 50 women aged 30 to 50, who received regular Botox injections for two years.
"We found that after the patient receives Botox injections every four months for two years, the frequency of the injections can be changed to every six months and still achieve good results," Dailey said.
"This demonstrates that patients have the ability to achieve good results with broader treatment schedules and ultimately at a lower overall treatment cost," he added.
Botox has been approved for cosmetic use for eight years. In 2008, more than five million patients in the US received cosmetic Botox treatments, according to Allergen, the manufacturer. About 313,000 of those patients were men, an OHSU release said.
The results of Dailey`s work were presented at a meeting of American Society of Aesthetic Plastic Surgeon last week in Washington D.C.
