These include reduction in the appearance of fine lines, wrinkles, skin pigmentation, stretch marks as well as acne scars, amongst many other conditions.The effectiveness of micro-needling has be reiterated repeatedly through human testimony, though has also been substantially backed by science.
Here is a summary of a some studies that used micro-needling treatment via Dermaroller use.
A study by Schwarz and Helmut in 2011, found positive effects of micro-needling use with a dermaroller device in 10 patients with post-traumatic or acne scars. This study was carried out over a 6 week period using punch biopsies and histological samples to find quantitative measurements of collagen and elastin formation. it was found that 7 of the patients experienced a 1.1 to 2 fold increase in elastin formation and 1 patient experienced an astonishing 10 fold increase. Furthermore, an increase in dermal thickness and collagen formation was observed. Patients also stated that they were pleased with the results and acknowledged that they would undergo another Dermaroller treatment. The procedure was very well tolerated. There were no side effects reported and no patient had to interrupt his or her daily routine or leave work.
This study also eluded to the indication of micro-needling as a treatment of stretch marks. A paper by K Park et al. found that rolling significantly improved the early and late stages of stretch marks in Korean women. Overall, this paper only observed positive effects of micro-needling treatment in human patients.
