This machine may help improve skin firmness and support facial contouring over time, but it does not replace fillers. Fillers are used to add volume, while this device is designed more for skin tightening, firming, and body/face contouring support. If your main concern is mild skin laxity, the RF facial head may help with consistent use. If you have significant volume loss, deep folds, or sagging, please consult a licensed aesthetic professional to decide whether fillers or another treatment would be more suitable.
