Is there any side effect for using RF in order to lift my breast?
No providing you choose your practitioner wisely...I would suggest a medical practitioner ( preferably a doctor) or at least somebody with genuine qualifications and experience in using RF.
That being said, i would encourage you to be very conservative in your expectation of how much RF is going to lift your breast. It may well be worth exploring all your options and having a proper assessment. be sure to ask your practitioner about their experience ( preferably with some before and after photos) in using RF to lift breasts.
I hope this helps.
