Why Dermarollers and Needling Do NOTHING for Stretch Marks

Years ago I read a book, The Concise Guide to Dermal Needling Expanded Medical Edition In that book, the author explains why needling doesn't work for stretch marks. Among other things, the gap is too wide for the fibroblasts to "sew" the skin together. Yet, I was so desperate, that I gave it a try, anyway, especially because there are people online who say that after years of needling, their stretch marks disappeared. I started needling since 2009, stopped in 2013, read the book in 2014 and started again that year. I have needled every single part of my body where there are stretch marks. I have done the procedure in doctor offices, I have done it at home, I tried different needle length, I tried different types of dermarollers (dermastamp, single needle, electric dermapen, tattoo machine with a permanent make-up artist), I applied Retin A, vitamin C. You name it. No difference. Not even the slightest, tiniest improvement. I am a very objective and reasonable person, with an analytical mind, so, if I say that there was no improvement, you can trust me on that. Yet, to this day, there are thousands of reviews online saying that stretch marks disappeared or improved after needling. I think what happens is this: there is a placebo effect. Dermarolling and needling are very painful, so, people think that if it is so painful, it must work somehow; again, a placebo effect in that people are so hopeful that their stretch marks will disappear, that they end up believing they are disappearing; after needling, there is edema (swelling) and redness. These inflammatory reactions might give the illusion that the stretch marks are less prominent, but, once the redness disappears and the inflammation is over, the marks are there again; before and after pictures mean absolutely nothing. They are taken from different angles, different distances from the camera and, most importantly, different lighting. anybody who says that Bio Oil or some other stupid oil works to prevent or minimize stretch marks, should be arrested ???????????? I hate when people give false hopes. Sorry for the long letter. I hope the day will come where these marks will go away. I haven't gone to the beach in years because I am so embarrassed.
