Can RF replace dermal fillers? While radiofrequency treatments are excellent for tightening sagging skin, they don’t restore volume like fillers. RF works best in areas with mild to moderate laxity, such as the jawline and under the eyes. For patients looking for a natural lift without needles, RF is an effective option. However, in cases of deep volume loss, especially in cheeks or nasolabial folds, fillers remain unmatched. Many experts now recommend a combined approach—using RF to tighten and fillers to volumize—for long-lasting, youthful results.
