Facial using ultrasound or radiofrequency - do they work?

[Thinkinghappythoughts]

Was at beauty salon today and noticed that they had a range of facial treatments using ultrasound and radiofrequency fir anti aging. Basically has anyone has them? Any results?

I tried something called Promax radio frequency about 8 sessions, didn;t do a thing for me, my daughter had it too. not for her either, although they say you don;t notice it straight away
It is supposed to build collagen, like most things these days, but i feel its just another gimmick,

I had ultherapy o my neck which made no difference whatsoever after 6 months so the clinic added on 6 sessions of RF facials. Again it appeared to make no difference until some months later I realised my neck, jaw and jowl area were much firmer and tighter. It took a good ten months to have an effect.

I don;t think what i had was actual ultherapy, but a milder type, but anyway my neck is worse now than it was,but that is just natural ageing i think,but it didn;t make any difference
I wouldn;t waste my money on it unless they had before and after pics
