It has been years and years that have passed until the FDA (the Food and Drug Administration of the United States) has given the green light to an injectable treatment for cellulite. It's called Qwo and it has the honor of being the first of its 'kind' to be approved by said association, thus becoming a source of attention and expectation by scientists and the public.

"It's a less invasive treatment option for women with good skin firmness, meaning no loose skin, who are also bothered by cellulite dimpling," says Shari Marchbein, M.D., clinical assistant professor of dermatology at the New York University School of Medicine, who has given an interview to Allure magazine.

Although this injectable treatment might lead you to think that its results are instant, they are not. Although some patients notice improvement after one or two sessions, it usually takes 12 injections (one vial) in 12 sessions that last 10 minutes or so and that are similar in pain to a Botox injection.

There is likely to be a side effect, but it is temporary. "All patients will have bruises," says plastic surgeon David Shafer. "The blood vessels around the area 'leak' a bit, causing internal bruising. It's nothing dangerous, but it can last for about two weeks."
