Peer reviewed studies on microneedling for aging, does it really work?

Question

My derm said that microneedling does nothing and there are no peer reviewed evidence based studies on it.

Below is a review article about microneedling, with a long list of references.  While a lot of the studies focus on acne scars, new advances and uses continue to develop.  I personally feel it has a great effect on fine lines and wrinkles, stimulating collagen, and a refreshed appearance.
Good luck,
Dr. Powell

Peer reviewed evidence is important in regard to credibility. However, even "peer reviewed" studies may have their own biases and, in fact, could be quite misleading. The conclusions do not always match the data provided so one must have some skills in order to determine whether or not a peer reviewed article is actually worthwhile. Regardless of the studies that are published in quality medical journals, one must also learn to decipher anecdotal stories about the procedure itself. I know people expect results with microneedling and the expected results may indeed interfere with a non-biased opinion about its effectiveness. The same holds true for doctors who offer microneedling. Based upon what I have seen with my own eyes, the procedure does seem to offer benefit for wrinkles and scarring. Your dermatologist is correct in telling you that there is little evidence, in regard to scientific studies, indicating that microneedling works. However, there is also no evidence to support the stance that it does not work.  You can't have it both ways! If there was a study proving microneedling does not work, I'm sure most doctors would cease using it, but that has not happened to date. I believe it will be shown, scientifically, that it does work, but that retrospective study has also not been done yet. As you can see, it is simply a matter of opinion at this point with some waiting to see if it is proven to work before offering it in their practice.
