With RF Microneedling, what causes the collagen growth? Is it more the micro needling or RF?

Micro needling causes collagen response via the "injury" of the needles themselves, whereas RF micro needling uses both the mechanical response from the needles AND the radio frequency energy which creates an elevated response by heating the tissue beneath the top layers. (This "beneath the surface" action is what makes RF microneedling an ideal choice for skins with more pigment or more pigment potential.)

RF Microneedling devices have programmed settings to insure you don't have too much heat within the tissue. The simpler devices may only target one depth, while newer devices have the capability of multiple insertion depths - this to include more tissue heating.

The needles are the "avenue" for the radio frequency energy, so the more areas those needles visit, the more response you'll get. With some devices you'll only have one possible depth of penetration; others offer more options.

One of the aspects of microneedling that most people are unaware of (though the doctors know!) is what's called impedance. This is simply the resistance your skin offers and this resistance varies over the area being treated.

Our practice has opted for an RF microneedling device that detects levels of impedance, so the RF delivery is adjusted, making sure your skin receives consistent energy during the treatment. It's a novel concept and one that's employed to give the most predictable outcomes. The idea is to get the appropriate amount of energy - not too little nor too much.

The RF Microneedling would assist to repair your collagen and the Radio-frequency can assist in toning the texture of your skin as well. When collagen levels are high, the skin is soft, smooth, and firm. Collagen helps the skin cells renew and repair themselves. Collagen also helps keep the skin moist. A consultation is best to determine the depth of any acne scars as well. Medical grade skin products as an at-home regimen is also an essential part of your skin rejuvenation process/regimen.

Thank you for your question. RF microneedling provides precise coagulation, or heat, to the skin and tissue to promote collagen production and enhance results. Deeper needle depth does not necessarily correlate with better results. The combination of the two can help with acne scars, fine lines and wrinkles, and the overall texture of the skin. I would recommend scheduling a consultation with a board certified plastic surgeon to develop a personalized treatment plan. Best of luck!
