Warning - long post
I too have had great improvement with dermarolling and I am so pleased.
Most significant and important to me is improvement of vertical lip lines. I wish I could have taken good pictures but it is hard to see the detail - but I know the wrinkles are becoming shallower. I used the 1.5 mm roller first in April, then decided to use the single needle to the vertical lines themselves, along with 1.5 mm dermastamp to the entire surrounding areas, repeating at 6 week intervals, for a total of 3 treatments to date. My lines are quite deep at the lip border, then gradually become less deep as they go up toward the nose. The shallower upward extending lines are improving the most. The deeper lines are not as deep as they were, and don't appear to extend as far vertically, so they seem shorter now.
I have never smoked, these wrinkles are hereditary, my grandmother had them and my mother has them and they never smoked either.
I pricked the lines first going straight in with the needle, then repeated from an angle from each side. I tried to prick in one continuous line. It was tolerable after using Dr. Numb cream.
I single needled, rolled, and stamped the other wrinkles that I have, slight marionette lines and crows feet. They look a bit shallower and the skin looks plumper. I have also been using the dermastamp under my eyebrows as the skin is rather saggy there, and it seems a little better. I do avoid the periorbital area.
For good measure I roll my entire face with the 1.5 mm roller every 6 weeks along with the single needling and stamping as above. I watched Heather's video on youtube and follow her technique.
I have also been using the 1.5 mm roller on my arms, lower thighs, and inner calf areas, with great results! It helps that there is some subcutaneous fat in these areas. The crepey appearance is diminishing.
I am following the daily skin care routine as per Sarah's instructions, and I'm finding my skin tolerates the tretinoin 0.05% cream very well. I can use it a couple days in a row, using the homemade Vitamin C serum in between. I found also that my skin looks better if I use a .25 mm roller during the week instead of a .5 mm roller, not sure why. The .25 mm roller makes my skin look plumper, whereas the .5 mm roller makes my skin look "tired", if that makes sense.
Also, this past time I needled/stamped/rolled, my skin had no bruising or discoloration the next day, even though there was plenty of bleeding after needling. I even used tretinoin right after needling/rolling, as I had put a 2.5% Vitamin C serum on afterward and it didn't sting, so I figured why not try the tretinoin. I'm wondering if my skin is getting more healthy following Sarah's skin care routine. I was also careful to avoid taking my daily fish oil for 4-5 days prior to needling, which I had not done with the first 2 sessions, where I did have some bruising. Anyway, I'm pleased that my skin seems to be tolerating all treatment very well. Which surprises me a little, I am 53 years old and didn't expect to bounce back so quickly.
Thank you Sarah for your products and your guidance and expertise, you have really helped me. I'm so glad I found your site. I was getting really depressed about my lip lines and have been considering the laser resurfacing treatment but it is so expensive. I still may get some filler to the lips and/or above the lips to help with the fat/volume loss, but that is expensive too. I feel like I am making such good progress and plan to repeat my treatments every 6 weeks. Will continue needling/stamping/rolling while saving up for the other treatments.
