I purchased one of the original face gadgets, before they came out with the two-prong eye attachment. You have to use it every day, it's tedious and time consuming. I ended up returning it. I saw no difference before/after on my face but I was much younger then, lol. I also read, at the time, that it's not recommended using it on your neck in the thyroid area. You can use aloe vera gel, the gel they sell gets expensive. You have to be really dedicated to use it every day and, believe me, the novelty wears off after a week or so and it just gets tedious and annoying.
I purchased a red light gadget, hand-held, not full face, when they were all the rage 10 years ago or more. I had acne breakouts until my mid-fifties and the red light gadget did help with acne breakouts. Wrinkles? Meh, no difference. Again, like the Nuface, you have to be dedicated to use a red light gadget every day and it's also tedious and time consuming.
Are we tired of “winning” yet?
