Microneedling: The Details Matter!

dermarollerMicroneedling and Dermaroller:

This was a great catch by Gin Amber.  RF microneedling can go too deep and actually get rid of subdermal fat.  You don’t want to do that to have a youthful looking face! Keep the needles to less than 1 mm in depth. Fraxel treatment also goes more than 1mm to 1.7 mm, so that can be counter productive in older skin! See  Transcript below.  (I’ve referred to microneedling using the dermaroller here.    Full disclosure is that I cannot find any studies on the dermaroller and its efficacy scientifically.  But it is still my “go to”, as an added boost for skin care. I just don’t trust lasers.  Perhaps they’re better than they used to be, but I’ve still heard about patients who had changes to their facial pigment, and thinner skin after.  So, in keeping with my philosophy of going with the body’s own systems using hormesis and doing no harm, I’m sticking with a dermaroller, science backed topicals, as well as oral supplements.  I, personally, have used up to a 1mm dermaroller, but the quality matters.  I’m currently using a GloPro .3 mm roller.  It’s smooth and great quality.

 

deep
radio frequency micro needling and what do I refer to as deep? Anything above 1 millimeter keep that number in mind because if you go in and you get say
Morpheus 8 treatment because why wouldy ou do it? Well, you’re trying to tighten up your skin and your jawline and your neck and uh it’s supposed to
stimulate collagen etc etc. So you go in and do it you’re probably doing it at depths greater than a millimeter. And when you do it at depths greater than male meth
one millimeter gets guess what’s there it’s your facial fat so what ends up happening is the skin of the face is almost at the deepest levels about a millimeter most places it’s even more uh thin than that so you put energy through radio frequency micro needles that bring energy and heat into the layers at uh depths greater than a millimeter so 2 3 4 millm sometimes even up to Where your needles are landing, where that energy is landing is subcutaneous fat. Subcutaneous fat means fat under the skin. When heat and fat mix, fat melts. When fat melts, guess what you end up with is skin that is no longer as supple skin that has actually lost its supporting fat layer underneath it, which gives it its structure and integrity over the fascia, and the skin actually looks older. So people have said this for years now and I swear when I first heard it I thought they were you know just kind of like I don’t know saying saying some stuff that I didn’t believe but then I saw it over and over again. I heard it over. Now it’s it’s a it’s a common truth. Everyone who’s you know been doing this long enough and has seen this long enough recognizes that there is thermal damage. There is loss of subcutaneous fat and as a result the faces actually look older after they’re doing this doing a treatment that was supposed to make their their face look younger.
