Derma rollers have a number of uses, but the main ones are for improving pigmentation issues and improving the surface of the skin. Fine lines, acne scars, and hyperpigmentation are all said to be diminished with regular derma rolling.

Derma rolling is a minimally invasive procedure so as long as you use the right technique in conjunction with the right serum, you’re unlikely to experience side effects.
