Microneedling With Regular Insulin Versus Microneedling Alone in Treatment of Atrophic Scars

Microneedling With Regular Insulin Versus Microneedling Alone in Treatment of Atrophic Scars

Recently, few studies have attempted to test the regenerative effects of human insulin application by microneedling on atrophic scars versus other topical preparations. However, the scars were limited etiologically to acne scars. In addition, a lack of inclusion of a control group instead of comparing topical preparations with insulin was also a limitation to these studies. A control group consisting of microneedling alone would have served as a better comparison in order to determine whether the effects of microneedling are augmented by topical protein-rich preparations.
