Microneedling with lasers helps scars. I suggest you see an expert for treatment options and post photos. Dermaflage is very helpful as well. Best, Dr. Emer.
Microneedling is unsurpassed for most scars. If there still is redness to a scar I would start off by recommending treating the red first with a laser. Once that fades, if there are textural issues microneedling can be started on the scar. I usually recommend treating an entire subunit on the face, ie: entire nose, entire chin or wherever the scar is located so that the needling injury as it heals, blends the scar in better. For scars you need deep needling so make sure you have someone with the license to treat that deeply.
Microneedling is a great choice for treating surgical scars with minimal downtime. This will take several sessions and really depends on type of scarring. For darker skin types I prefer Microneedling over Fraxel to lower the risk of post-inflammatory hyperpigmentation. The Fraxel dual also works very well for surgical scars.
