I have some scars from life. Acne, chickenpox as a kid, nothing major but enough you notice in a magnifying mirror. I had seen some micro needling reviews talking about if filling in some light depressions and scars. What could it hurt? It does an amazing job and does not break the bank at 30$. Totally worth the investment and you see some improvements with use 3 times a week for a month.
