Dermal rollers are the previous generation of needling devices. One of the many drawbacks of dermal rollers is the fixed needle or penetration depth (i.e. 0.5mm) which is not very conducive when treating an area like the face which requires different depths due to the varying thickness of skin tissue, depending on the area(s) being treated. Therefore, having a fixed needle depth or penetration level is a huge drawback when trying to customize a treatment for consistency. Micro-needling has an adjustable needle depth that allows your skincare provider to adjust penetration depth throughout the entire treatment. This will allow the medical provider to properly address the specific needs of thinner skin on your lower eyelids, crow’s feet, and forehead. Additionally, where the tissue is thicker in other areas, like the upper lip, cheeks (due to fat pads), neck and décolletage, the necessary adjustments can easily be treated with 1 needle tip instead of 5 or 6 needle rollers. The other dramatic difference is in the type of injury that occurs with micro-needling versus a dermal needling roller.
