@burcidi-- I do think that there are benefits of electric facial massager that other products can't really offer. Better blood circulation is definitely one of them and for cleansing massagers, those promote the making of new skin cells so the skin is clearer, firmer and brighter.
I've also heard doctors recommending a facial massager to their patients because it promotes lymph drainage. This apparently helps a lot for people suffering from sinus infections. It also helps strengthen the muscles in the face, treats swelling (water retention) and lifts the face.
