With my limited knowledge if chemistry, physics and biology... I think we need to know for certain if all metals have equal conductivity. What type of metal is used for fillings (sone sort of alloy, perhaps different metals) and teeth straighteners.
What would the negative effect be here, if this ellectro current reaches a filling or a teeth straightener?
Also, the device has different settings so maybe some levels are 'safe'.
I think Nu Face works on a similar principle. What are the precautions advised by the Nu Face manufacturer?
And how does Foreo Bear compare with Nu Face in terms of current intensity. For ex., is Foreo level 5 equal to Nu Face level 3? I don't actually know if Nu Face has levels but just as an idea.
I know Foreo has some contraindications related to heart but I can't remember what they were because when reading on this it didn't apply to me so I didn't bother to learn on this. I just told myself not to go below the neck with the device.
It will be interesting to see what the real feedback on these devices will be in 30-40 years time. A bunch of old women suffering from various health issues caused by regular exposure to micro currents? Or a bunch of old women with some magic superpowers? I'll be one of them obviously but I'm hoping to have maintained a nice sharp face outline without too much sagging. My Foreo will, of course, be joining me in the care home. Unless it will be replaced by some other new gizmo.
(Currently obsessed with getting a Lyma, but even with their 20% off I really can't justify buying it).
