About three months ago I finished my third session of RF Microneedling. After each session I noticed prolonged but slight redness. I mentioned it at the beginning of each new session and emailed a few times about it. Each time I was told it is new skin forming and it will lesson. In a week it will be three months since my last treatment. My stretchmarks look worse. They seem wider and thinned. Beyond that, there is still a mild redness that makes them stand out even more. Is this normal?
