Patients can expect to see results in about 10 weeks. Your provider will determine how many treatments you need, but typically it is three treatments spaced three weeks apart. QWO clinical studies have included more than 1,800 women – the largest clinical studies ever conducted on cellulite. In two pivotal studies of 843 women, about half received treatment with QWO; the others received a placebo with the QWO treated buttocks showing statistically significant improvement. There were no serious side effects among the study participants, just bruising at the injection sites, which lasted several days. However, QWO may cause an allergic hypersensitivity reaction. A five-year study is currently underway to determine the longevity of the injectable’s results.
