Microneedling DC is an outdated, inexact technology. Although chemical peels can still be useful, most people consider laser resurfacing the best. There are many types of lasers, including fractionated and CO2, erbium. While some claim to speed up healing, the most important thing is how deep and how much they penetrate. Lasers that penetrate deeper or have a lower penetration rate are not as effective at healing. There is less injury, and therefore a lower final result. Laser injury with a deeper penetration and greater density results in a more controlled effect and a significantly higher resolution of wrinkles.
