Cheek filler treatments are generally safe procedures when administered by an experienced professional. Dermal fillers used in the cheeks are low-risk and generally only produce mild side effects (such as bruising or redness) that resolve within a few days post-treatment.
A topical numbing cream is applied before your injection which minimizes any discomfort during the procedure. Some patients experience a mild stinging or pinch, but this is not considered painful. Cheek fillers require little to no downtime, which means you should be able to resume your normal activities after your procedure.
