Once the bruising has resolved, I think it is ok to begin hydroquinone treatment. So 5 weeks should be a sufficient amount of time. Good luck!
Hydroquinone should not be used on the area you had Cellfina. The red/purple spots are most likely petechiae from the suction as well as the multiple needle puncture sites. This should resolve on its own within the next two weeks. Re-visit your healthcare professional if you have further questions or concerns. #cellulite #cellfina #bruising
