You'll need to be more aware of what not to use with your dermaroller. "You typically would not use any acid-based or retinol products immediately after microneedling unless directed to do so by a skin care specialist who knows your skin," says Ciraldo. "This is because the enhanced penetration of aggressive skin care products after microneedling can result in a severe irritation at the skin surface."

But, non acid-based products are fine to use — in fact, they'll penetrate your skin more deeply and be more effective if you apply them immediately after microneedling and the next few days after. Using a great serum is especially beneficial.

You should get instructions with the device, but, if not, Ciraldo advises using a cleaning solution that is 70 percent ethyl alcohol; hand sanitizer or rubbing alcohol should work just fine.

"The manufacturer may have guidelines for how often you should replace either the entire device or the needle cassette. They are usually fine for at least one year," she says.
