Derma-rolling or micro-needling is an at-home treatment where you use a small rolling pin-looking thing that is covered with needles. And you basically puncture your face with hundreds or even thousands of very small holes on the surface of your skin. Sounds scary, but trust me when I say that derma-rolling might just get you that flawless and glowy complexion you’ve been searching for – it’s also super effective for getting rid of those pesky under-eye circles.
