Q: How often should you use a 0.5mm derma roller?
A: Once a week at most, and less often if skin feels sensitive afterwards. Longer needles need more recovery time between sessions than a 0.25mm.
Q: Do derma rollers actually work?
A: Used consistently and hygienically, many people see improvement in skin texture over weeks rather than days. Consistency matters far more than pressure.
Q: How do you clean a derma roller?
A: Rinse under hot water, then soak the head in surgical spirit for a few minutes and let it air dry in its case. Do this before and after every use, and never share one.
