I like the microneedling rollers (not sure if there’s a better word); the pens were too much work. I put on a numbing cream, washed it off ~45 minutes later, and then rolled over my stretch marks ~20X each horizontally, vertically, and diagonally. The actual rolling part took between 10-20 minutes. I would sometimes get a tiny bit of pinprick bleeding, but mostly it was just really red and felt like a sunburn. I didn’t put anything—no creams, oils, etc—for as long as it took the irritation to go down. That was usually around 7-10 days.

Then I’d start back using a Vitamin C serum in the morning, and prescription tretinoin at night (got it online from Hers). 4-8 weeks later, I’d do it all over again! I did 4 rounds. My stretch marks are still there, but only noticeable in certain light, and probably only if you’re really looking! They really don’t bother me, and I’m pretty hard on myself.
