I'm not sure what you mean by high frequency wands, do you mean this? u Wand? [Edited link out]
If you are talking about the u-wand, I used it for a 30 day cycle twice a day and it completely cleared my face. I used to be in an oily, then too dry, then too oily again cycle constantly and had moderate to severe acne. I use it once a day, sometimes once every other day, and nothing has popped up in the last two weeks. It was seriously a game changer for me and the acne I had.
Is this what you were talking about?
Bump. I ask for high frequency every time I get a facial and highly recommend it. The wand works, not quite as well as the old school electrical node they used to carry in European spas but it gets the job done too. Ask your esthetician to use high frequency after a facial. It helps disinfect the area, especially after extractions.
