A 0.5mm derma roller should be used once a week to start. You can increase the frequency if your skin responds well, but don’t use it more often than three times a week. 1.0mm derma rollers should be used no more than once every 10 to 14 days, and 1.5mm rollers should only be used once every 3 to 4 weeks.
